[Q] TF101 Screen won't turn on

Hi everyone, this is my first post here. Thanks in advance for any help that you folks can provide.
I've had the TF101 for about six months now, and it's been fine. I was using it yesterday on the train and all was good, but when I got home and took it out of my bag it didn't seem to start up. I thought it might have been a battery issue, so I let it charge overnight. Tried starting it up this morning and I got the same results. So I started looking in to other issues.
The tablet is definitely starting, adb will recognize it in its list of devices, and if I plug it in to my tv or desktop monitor w/ HDMI, I can see and interact w/ the Transformer UI (of course this is kind of painful since I have to do some guessing about where to put my fingers).
I had rooted it using rebound821's scripts and directions here, so tried an unroot to see if that was the problem. I ended up with the same results.
Does anyone here have any insights as to what the problem may be? I'm hoping to avoid sending it back to ASUS, so I'm fine w/ opening it up to look for loose cables.

So I thought that brightness might be the problem. Maybe it was set to 0 and I just wasn't seeing anything on my screen. Sadly, that doesn't seem to be the case.
I tried setting brightness at the path below to to 0, 50, 100.
/sys/devices/platform/pwm-backlight/backlight/pwm-backlight/brightness
Still no luck.
Has anyone encountered anything remotely similar to this (even if similar is just a dead screen)?

There have been others with dead screens reporting what you are, at least I have read a few reports, I think they just had to get them RMA'd, I don't recall anyone 'fixing' a dead screen, especially if you still have adb and touch working then the screen itself and backlight seem to have broken completely- some have reported the backlight dying and thinking the screen was broken, but it was just the backlight (I guess in bright light they could see pixels working, but couldn't make out what was on the screen without the backlight). I still think they had to get it repaired either by Asus or by someone who was capable of doing internal repairs with replacement parts..sorry for your luck

Looks like I'll have to send it back. I took it into the brightest light I could find and couldn't see anything at all. Guess it's the screen and maybe the backlight too. I'm pretty disappointed this happened, the only thing I can think of is that the bag I had it in was hanging from the chair in front of me on the train and it was swaying a little, and that shouldn't be enough to dislodge a connection. Either that or just some freak hardware failure. Still, I guess it's not that common of an occurrence. Thanks for the reply, I'll slink off and try to get in touch w/ Asus now.

I have experience same
My TF101 broke in the same way, screen blank. Conected to tv I`ve got image digital touch work. I shut down my TF101 normaly and screen never go back to live again. Tablet was in a protective bag (when I trave by car), just no reason for not working ( no problem at screen, previously, screen perfect - no dead pixels)

Did you guys get this resolved? I had the EXACT same thing happen yesterday. Was working just fine. Put it in its sleeve, into a protective case, into a briefcase, got home and dead.
HDMI works. I tried to call Asus but they say i'm out of warranty.
Thanks in advance.

Must be something wrong with the connections that it decays over time. I've had mine since October last year and its been fine except for today when I brought it home it wouldn't work.
I was able to fix it though. I held it vertically with the bottom edge down and tapped it firmly on my desk a couple of times. The screen came back on. There is a strong possibility that this will happen again and my tap fix won't work, but it's working at the moment

I had exactly the same problem discussed in this thread. I was also able to bring the screen of my TF101G to life by tapping it firmly on my desk with the bottom edge. It works for now. But it is certainly disconcerting to know that some connection in this rather expensive gadget are loose and all this can happen again. I guess I will not carry my transformer around any more - just leave it at home...

Same problem here had my unlocked bootloader tf101 for awhile now, one of the first ones out... had a great life gave it to my girl when i got the transformer prime and the screen just went out yesterday, still goes in apx mode and still recognized by computer, screen just straight up died, think it's too late for a manufacture warranty, maybe ill look but think it's gonna be no dice... sucks obviously something in the design to make this happen to so many of them...

My TF101 appears to have a dead screen. I am rooted and running Revolver Custom Rom. When connected to my pc, I am able to recognize my device. My screen will not turn on so I cannot use recovery to go back to stock. I am set up to use ADB, however, I am not very knowledgable with ADB. I am convinced I have a bad screen and I am still under warranty. Is there a way to return the TF101 back to stock using ADB? If anyone can point me in the right direction, I can probably figure it out. Otherwise, I may just try and replace my screen and see how that works out. Thanks for the help.

My backlight died on Tuesday. Similar situation of working in the morning, headed into work with it in my bag, no brutal knocks or anything but one jolt just must of finished it off after a year and 2 weeks abuse (yes 2 weeks out of warrenty).
Going to attempt to take it apart this afternoon and play with the ribbon cable as reseating it has solved quite a few peoples problems.

Woo! It worked! Very happy chappy.

Screen goes derp
I don't know if I have the same problem or not.
Backstory: I own a Transformer TF101 that I got for my birthday from my girlfriend. It was meant for travel and bs'ing around at home. Took it into work and quickly realized that I could use this for work. That went over so well that the rest of the office became intrigued. Once these came on sale on groupon, the office manager went all in on 10. These are all refurbished transformers with docks.
They have all been handed out and I now have a transformer for home and work. Kind of nice...but I do a lot of site observation so using my personal transformer was a risk that I had to take all on my own (survived a 5' fall off of a parapet wall already).
The problem: From the first 5 minutes that I had the thing, the transformer screen went blank. I opened up google play to download a few apps that I could use for work. Scrolling down I saw some choppyness which I considered the processor/memory having issues loading everything on the screen. Before I knew it - boom blank screen. Rebooted and the loading screen stays on for 2 seconds before the screen goes blank. I can tell it's working because it plays a sound at start up. I can also tell the screen is lit up (it's like it's showing a grey screen because it can't show true black colors). If I hit the power button again it goes completely black. I hit the power button again and the screen flashes to the lock screen and immediately goes blank again. I could do this over and over and over again.
Anybody having the same problem? It's refurbished....I'm guessing apparently I got the dud.

I ran into pretty much the same problem. One morning, the tablet screen would just not turn on. Sometimes, it came on and immediately shutdown, but it is still on the "On" mode. Hit the power button again will bring it to the off mode. Toggle it one more time, sometimes, will turn on the screen a off again. I was able to get it back to work with a factory restore. However, it has the following problems.
1) As soon as I adjust the brightness, the screen will go off again. And there is nothing I can do to bring it back except another factory restore.
2) The screen will flicker (and sometimes produces some clicking sound) when charging with the screen on.

Looks like my TF101 is having same issue, screen gone off suddenly (hdmi shows up in TV fine)...I am going give a try on reseating the cable hoping it resolves the issue.
leonpr, is there some tips/things I have to make sure before attempting this. I found a guide here and another youtube video on this issue as a reference...
Thanks..

Screen won't turn on unless factory reset "fix"
My girlfriend has an ASUS TF101. If the brightness goes up to 60%, the screen is blanked (no backlight either) and the only way to get it to turn back on again is to hard reset. This coincidentally happened at the same time as an update from ASUS. After lots of Googling it does not appear to be related. I was hoping it was and installed several custom ROMS which all experienced the same issue.
As a temporary work around, until I get the guts & the money to be able to replace her tablet if I break it, I found and installed AutomateIt. I set a trigger so that when the screen is turned off, the brightness is set to 50%.
Why trigger when the screen is off instead of when the screen hits above 59%? If you have this same problem, hold the brightness and go all the way until the screen blanks and then still holding your finger on the screen, move it all the way to the left and you will notice that the screen did not come back on. Press the power button once to turn it off and then again to turn it on and you will see the screen at the lowest brightness setting.
So, with the trigger in place, if you accidentally (or one of your rotten kids intentionally:angel raises the brightness above the threshold, simply press the power once to turn off the screen and then press it again to turn the screen on.
Just a note, I ended up installing AutomateIt Pro, Available for $1.60 from the Play Market. The free version works fine, but my girlfriend has been struggling with this issue for a couple of months and after so many hard resets, the little app is more than worth the money.

Have you tried Power + Volume Down for 15 seconds, and then leaving it alone for one minute? It will cold boot. Try that and it may work. Just saying; Hope it will help

Sorry for the necro-bump but here's the actual solution.
Problem: The video cable inside the Transformer comes loose and just needs to be pushed back in.
I can't post a link since I don't have 10 posts yet so just search youtube for the following key words:

Just fixed my blank display problem on a TF101 which is well out of warranty. Here is the link. I found the connector loose after dropping my TF101.
Thanks!
Fix lasted for a few days, now backlight dead, tried all cables again. No joy . I hate intermittent faults so ordered a Samsung Galaxy TabPRO 10.1.

[Q] No tablet display but HDMI works.

Hi,
Yesterday (08/02/2013) I updated my tf700t, everything seemed to be fine after it rebooted, I was playing a game, the battery was low, and it turned off abruptly. I assumed it automatically shutdown because of the battery, so I put it in the dock and plugged in the charger. Several hours later I tried turning it on and nothing. I held down the power button for 8 seconds felt the double vibration, but no display. I tried various combinations of docked/undocked, power cord plugged in, holding the power button for 30-60 sec. etc. but nothing.
Out of curiosity I connected the HDMI to my computer monitor and sure enough, it was there, I could unlock it and everything seems to be functioning fine, just no display. The digitizer seems to work fine, although guessing where things are at is pretty tough.
I think I tried the cold boot, volume up/down (I tried both) plus power, and it didn't make a difference.
In order to do the update I had to flush the DMC Client and CMClient data and cache, I had been getting errors from DMC Client crashing.
Also I'm not certain this is update related, as the tablet had been acting wierd, which is why I did the update. I would press the power button to turn the screen on and nothing would happen, so I'd hold it down longer and the tablet would reboot and finally the screen would come on, or it would come on a few seconds after I pressed the button. I was getting a lot of reboots etc... I thought the update might resolve this.
I'm not sure if the problem is hardware, firmware, or software related.
I'm wondering if when I flushed the DMC and CM Client cache, maybe I deleted the drivers for the display or something?
My options seem to be:
1.) Factory reset by feeling around the digitizer while connected to HDMI
2.) Factory reset via the pinhole
3.) Install new (old) firmware via usb/computer. (the device is recognized by Windows 7 so I think this is doable.)
4.) Send it off to Asus. (would this be free?)
So my questions are:
1.) is there something else I should try?
2.) what order should I do the above in?
*Note: I'd like to save my data somehow.
*Edit: I forgot to mention I was on 4.2.1, no root or anything. Also I bought this in July of '12 so I'm pretty sure it is out of warranty. Any idea how much it might cost to send it off? Perhaps I could replace the LCD myself? I replaced the digitizer/screen on an ipod touch, although I'm sure this LCD is much more expensive and much harder to replace. This is turning into a nightmare. So much for trying to keep my data, now I hoping to keep this from becomming a paperweight.
Thanks.

A bloke at work had this issue. He let it rundown and left it for 3 days. It worked fine again after that.

If you don't even see the boot logo, it cannot be software related.

Thanks for the replies.
I'll try letting it run down. Would putting it in the freeser be helpful/safe?
I guess on the software/firmware it depends on the definition. To me drivers are software, firmware is anything written in VHDL. I suppose what I'm really wondering is if it is software/firmware vs. hardware, i.e. is the LCD or some other component dead or is the display just not getting written to, initialized or whatever.

I wouldn't put the tablet into the freezer.
Does the backlight come on? If not, it's definitely a hardware problem. If the bootloader boots fine but doesn't show anything, that also looks like a hardware problem.

I'm not sure about the backlight, I think maybe it does, it is kind of hard to tell. I'll try checking in a dark room tonight. Since the screen is just black I suppose I'm looking for a brighter shade of blackness?
The bootloader is definitely booting fine. That is what I meant in my original post, the HDMI out works, I can see everything there, I can even swipe and tap the digitizer and do stuff, it is just difficult to guess where things are at. Do I need to go back and clarify this in my original post?
Do you think this definitely means it is a hardware problem? I figure I'll try letting the battery run all the way down and let it sit a few days and recharge it as sbdags suggested, in the meantime perhaps I should contact Asus, but I'm not lookinf forward to that.

I don't know what is the cause but like I said I saw this with my very own eyes - the same as yours. Double buzz on boot not screen but HDMI worked. Somehow completely draining the battery fixed it ...... So hardware / software? Who knows? If it was hardware why did draining the battery fix it? The device has been absolutely perfect for 3 months since and has never done it again.....

Thanks sbdags, I will definitely try this. I'm not sure if I should hurry and contact Asus though, I bought this thing around July 22 2012 I think so it is barely more than a year old, not sure if they would cut me some slack on the warranty or not.
Do you think I need to let it sit three days or just make sure the battery is good and run down before charging again? Also I've seen some suggestions for charging from a computer vs. wall as it charges slower, do you think that would be better?
I'm getting into panic mode and want to make sure I don't do anything rash that limits my options.

All he did was leave it for 3 days. Our assumption was that the battery had completely drained in that time....... A charge later (he was actually just about to box it to send to Asus) and it surprisingly started as if nothing had happened.

Having the same problem
I am having almost the same problem, except that the tablet screen works when the wall charger is plugged in. THe HDMI display and the digitizer work fine. It is just the tablet's screen dispaly when the charger is unplugged.

So I didn't have any luck letting it run all the way down.
I contacted customer support, the warranty is only 1 year, but fortunately for this there is an extra 3 months, so I just managed to squeak by, although I'm keeping my fingers crossed.

same problem as you both
i have d same problem well until last week the screen displays when conne ted to wall charger now its all blank but iy works via hdmi, digitizer works fine but all blank, this tf201, does anyone know if i change d whole display it will work?
i already bought the tf701
any suggestions is welcomed and did you get youra to work?

I have not seen people mentioning VHDL and verilog for a while, hahaha... It sounds like you are a low level or physical layer programmer. Any way, a firmware is in general a low level program that communicating with the hardware and the software or high level program ( level 7).. If you will, a firmware is a management levels (level 2 and 3). A VHDL is a level 1 which generates a 0's and 1's or mapping the transistors in the FPGA chip for example.... Oh well, it is just my definition...

If you can get the output from the HDMI port, it is more likely you have a hardware problems. I think that the problems are your display related hardware. If you really want to troubleshoot your issues, you can look on the mother board to locate all the electrolytic caps and check to see any abnormal signs of those capacitors. Those caps are the one that will blew up first before any others parts go....Good luck...:fingers-crossed:

[Q] Nexus 5 screen showing colorful static

Has anyone come across this before? I was watching a video on MX Player not too long ago, and it seems to have resulted in a permanent colourful static for the phone.
I can't really tell if it's doing anything, but when I go through the motions of resetting it or booting into bootloader, the screen does not change at all.
Interestingly the volume buttons are still working, and if I press the area of the screen where I think the buttons are (e.g., the back/home/programs buttons) I get the right vibrations. Which leads me to believe my screen is broken, and that it's a hardware fault. I'm hoping pretty hard this isn't the case, as my phone is only two months old and it was a replacement for a 6 month old Nexus 4 which had stopped charging.
Anyone come across this before? I'm hoping there's a kind of solution somewhere out there... To make matters worse I bought this phone via a parallel importer AND I'm currently overseas and won't be back till the end of January.
Sigh. Photo of screen is as attached - please forgive the terrible quality as I had to use my laptop webcam.
Thanks in advance, everyone!

Only time I've seen something like this was when my integrated graphics card on my desktop overheated, everything still worked, but colorful static everywhere. I'd let it cool down for a while, chances are it was pretty hot when it did that, and see if high temps might make it happen again.

I just had the same thing happen. Phone had been in my pocket and I had just taken it out to check the time maybe 10 minutes before it happened. The only difference with mine was I bumped into a table and hit the phone in my pocket. It does have a case on it and there is no sign of damage at all such as a cracked screen or anything. The static only lasts for a few seconds and thats right after I force it to reboot. After that it just goes to an all black screen. My LED indicator light is still flashing at me telling me I have an email though so I'm not sure what the deal is.

Were you able to resolve this issue? I too just experienced this issue as well and my phone is currently unusable. Thanks!

Do a full wipe as in wiping the entire phone and making it as if you just got it out of the box. if it persist RMA

Hi, I broke my screen (really bad smash) and had have this static on my new screen. The new screen was apparently fully tested. When using the slim port i can display on my TV and the digitizer works fine, its just this same colour static on the handset. I am now waiting for a replacement USB flex (it was a bit bent in the break) and i expect the new USB flex will fix it. If not then its a bad screen.
Will post the results when i get the parts

Fixed!
Hi,
My new USB flex arrived today. I installed it and found my screen is working perfectly.
The first pic is the same colour static that the op had.. Second one is the USB flex board / ribbon. Ebay for 20 Euro. Please remember that USA users are LG D820 and Europe/rest of works LG D821. I think its important for this part as the aerials connect here ans they are different in USA.
Good luck everyone

Static screen and freezing
Hi All,
Need help here with my 6 month old Nexus 5. It has been pretty good with no issues but since last evening, it started behaving weird. The chronological events are as follows
1. While browsing on Chrome some websites were not scrolling intermittently. This was only in the browser.
2. After about 10 mins of the above behavior the entire phone froze and didn't release itself. I had to force reboot by holding the power button down for about 10 secs. When the screen came on, it was the static screen
3. I again pressed the power button a couple of times but no use. Held it again for 10 secs, then phone rebooted and everything was fine.
4. Continued to use the phone and everything was normal until this afternoon, when the phone again froze while browsing a website
5. Since then the phone screen shows the static and if I press the power button once, the screen switches off and press again the screen comes on with the display showing properly. I can now only perform one touch which is registered and the screen freezes. If I switch off and on again the next screen / action is shown which is the action I did in the previous touch. Every time it registers one touch and I have to switch off and on again to see the next screen. Sometimes the phone just shows static and I have to wait a few seconds (30 sec) before using it again.
6. If I make a call to my phone, I hear one ring and then it is busy tone like I've cancelled the call. However the phone does not show the incoming call.
My phone has been intact and is well protected with screen guards and case. There is no physical misuse / abuse of the phone. I managed to shut down the phone and enter recovery. Here as well it only registered one touch, though the phone was processing and moving the next step. I somehow managed to initiate a factory reset through the settings, but no use.
Now in about 2-3 hrs the phone has become completely useless. I'm uncertain what the problem is, all my touch inputs are registered and processed. The screen just doesn't refresh to the next and requires a power off/on. I picked up this phone in the US and now in India. So I can't RMA the phone and I don't have warranty for this in India.
Any suggestion will be greatly appreciated.

I'm getting the same issue. Tried soft and hard reset. Opened her up and seated all cables. The issue is still persisting. Is replacing the USB flex the way to go?

Hey I have a nexus 5 32GB and the screen started to do weird things and now it isn't working at all. Its the same in recovery mode also do I think that it's not a software problem.
I think there is an issue with the motherboard. Please help me out.

Hey I have a nexus 5 32GB and the screen started to do weird things and now it isn't working at all. Its the same in recovery mode also do I think that it's not a software problem.
I think there is an issue with the motherboard. Please help me out.
Thanks in advance.

Anyone seen this colored screen?. I have been getting this past 2 weeks when phone is charging and screen is about to turn off. I am on stock not rooted.

Looks like the daydream function. You can turn it off in Settings>Display>Daydream

Same thing, Screen now black. Won't turn on...
Hey everyone, I know that this is kind of late to the thread, but I have what I believe is the same problem as everybody else here. I had my Nexus 5 in my pocket for maybe five minutes, and in between the times that I put it in my pocket and took it out again to reply to a text, the screen went all colorful and static on me (Red tint, almost as if I had twilight on, but I didn't). I tapped the back, and the colors went back to normal, but the digitizer wasn't responding to touch. Then, It went black. No color, the speakers weren't working, neither was the backlight on the display. I took it apart, and figured its either the USB flex cable (which looked frayed), or the mainboard. If its the USB flex cable, then I know I can repair it. If it's the mainboard... well, as a sixteen year-old who has no current source of income, I'm out of a $400 phone.
Pictures attatched. Thanks!

I'm getting the same issue. Tried soft and hard reset. Opened her up and seated all cables. The issue is still persisting. Is replacing the USB flex the way to go?

I took the phone the LG service center and the technician seemed to know this issue and immediately said that the USB flex cable needs to be changed. The entire fix took about 5 mins and the phone is working fine since then.
Sorry for the delayed response.

I hate to necro up this thread but I'm having similar problems to the op with my nexus 5. About two weeks ago I saw my screen get grainy just like the op and many others mentioned and then the screen went completely black. The screen still "turns on" but it's just black with the backlight on. I can hear notifications and other things and I'm hoping that all I need to replace is just the flex cable. If it's a problem with the logic board then I'm screwed basically.
Anyway that's my story. Bought the flex cable and it'll be here by tuesday so I'll find out then if I'm lucky or not. Fingers crossed.

Hey man, did you ever try this out and get it to work? I have the same problem and was thinking of trying this out but wanted confirmation first.
Thanks!

Just wanted to post here to say that this thread just saved me a lot of money!
Had the same issue (static showing on the screen). Local phone repair shop told me it needed a new screen, without even looking at it(!), and it would be £120 + labour. Told them I would think about it, and came home and did some more research, found this thread. Ordered a replacement USB flex cable from eBay, and fit it by following a YouTube tutorial, and now the phone is back working fine. brilliant!
Thanks xda!

I had a problem where my screen looked like an old CRT TV with particles flashing all over on anything with a static dark background. Any ideas

[Q] Arrrggh - The unit powers on but the screen $&[email protected]#! won't turn on .

Phone was at about 70 % plugged in at the time.
I went to check on something and the screen wouldn't turn on. It vibrates when I hold down the power buttons.
Initially I thought it was corrupted somehow so I flashed it using adb, fastboot command. I think I've flashed it properly . I even did it again for the heck of it using wugfresh. I can see it on the PC as Nexus 5.
Now I realize that it's probably the screen. It was dropped in water a few months ago but it's been okay since I replaced the battery. I pull the battery and plugged it in, there was no white battery charging indicator.
Any suggestions ?
Thanks.

Disassemble phone to check morherboard and screen for corrosion. Try to clean the connection points if possible. Depending on the problem you may have to buy a new screen or motherboard or both.

Can you see the internal storage through your computer and manipulate files and whatnot?
One thing you can try that isn't intrusive is to try a Slimport adapter and seeing if you can get the screen to show on a TV/monitor. If you can, that pretty much confirms it's the screen, and you can proceed to do what the above post suggests.

I took it apart and noticed a tiny bit of corrosion through the magnifying glass and cleaned as best as I could.

I can see the internal storage. There's nothing on it because I did a stock re-install but I can see all the folders.
The Slimport adapter is a good idea to confirm if it's a screen issue. I'll look into it to see if it works just by plugging it in . If so, I'll grab one off e-flea.

MTCD screen is displayed mirrored

I am facing a very strange bug since yesterday on my MTCD KGL.
The screen is mirrored, but the touch panel is not. So everything looks like seeing it through a mirror, but the touch panel is still in the correct orientation.
So e.g. a "Cancel" button is displayed as "lecnaC" and is on the right, but I still have to touch on the left to push it.
Even the boot logo and the recovery are mirrored.
WTF???
Do you have an idea what is going on with my unit?

Damn, this thing is not really usable anymore.
Just another "cheap" China product for the bin.
I should have better lit some cigars with the three 100€s...

So out of nothing it mirrord en before not?
Then it's software problem so fixable... flash MCU, flash image.
Everything comes form China nowadays, besides you know the risk if you want to buy cheap unit...

Yeah, did that already. Didn't help. That's why I'm like wtf...
Meanwhile I found out, that when I'm playing with the hardware power button, pressing it until reboot, that's flashing three times, then randomly pressing it short or long, I can change the mirroring from "flip over short side" to "flip over long side". But that's even worse. Did not manage to get it to correct orientation.
I know sometimes you win, but this time I seem to lose heavily.
Thanks pal.

This happened to mine and i couldn't understand what happened...tried every setting and a factory reset with no luck. And then one day it fixed itself. HOWEVER i did read on another forum a display cable comes loose inside and causes this. Just need to open it up and re secure the display cable...

This happened to my mtcb joying unit. I asked the manufacturer and they said it's like the graphics chip.

Normally these use a long ribbon cable to connect the internal boards together and then another to connect the display board to the LCD.
On my last unit the LCD cable was pinched by the metal case, causing random display issues.
Taking it apart and readjusting the cable so it was not pinched solved the problems.
Most manufacturers put the ribbon right at the bottom of the case, so any pressure on the bottom of the LCD can cause issues.

Hi there. Did you solved the problem? I have the same issue. What is the fix for this problem?

Sorry bro,
I have no solution.
It disappeared after a few week.
Sorry.
