[Q] Having screen flicker issue (Video), possible internal short? - Eee Pad Transformer Q&A, Help & Troubleshooting

TF101
Stock Android 3.2.1
Im getting this wierd screen thing going on. Anyone seen this or possibly have a solution?
When I tap the screen it comes back on... If I keep taping it, it eventually stays on, untill I put it in the dock or remove it from the dock, or tap the screen again.

Screen was recently replaced, I know now that If I apply a small amount of pressure on the top left of the tablet the screen stays on, when I let go it goes back to what the video shows above.

Possibility
I knocked my tf off a bedside table and could not get the screen to come on half the time. First, plugging it in or docking it seemed to help.
Finally, it wouldn't come on at all though I could see the backlight was lit. Not exactly what you are experiencing, but one thing I would check is to see if it looks okay through HDMI out.
I ended up opening the case (not hard, search Google for teardown instructions) and tightening a black video cable near the battery that had come loose. It's been fine ever since. I found info about it on slatedroid.

and I guess I haven't posted here forever. My sig is like 4 years old.

had the same problem
I might help you because i had nearly the same issue. My TF worked fine and from one hour to the next the screen flicker appeared. I decided to check it without sending it for RMA. i opened it very carefull and found the internal LVDS micro connector being loose alltough it was fixed with tape in production line. But 0.5mm out of the correct position was enough to start to flicker and show inverted colours. I dont recommend to open the device if you dont know how you should do it or have no experience in electronics...in this case, better return it for RMA...good luck!

[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.

Weird fault with Note 10.1. Help!

Hi guys, newbie here, and im in desperate need of your help!
So I decided to buy an Note 10.1 and yesterday I received it. Straight away (after turning on) I noticed this rather irritating noise (like a notification sound but not one that is the ringtones options on the tablet) that the tablet made when I held it with one hand well, at first I thought it was a motion gesture since whenever I hold it with one hand (the right hand) it switches to the previous app if your in an app, or previous Web page when surfing the net. So I searched the options 100 times, and nothing to toggle off.
Anyway it bugged me more and more and I couldn't figure it out, then by chance i just pushed slightly on the back of the tablet and the notification noise goes off. Push again, it happens again. I decided that it could be a loose connection being made and remade every time I decompress the right side back panel (I can play it like a piano). So I took the back panel off (a pain in the ****) and noticed a ribbon cable that runs directly where I push the back panel (the S pen sensor cable). It was plugged in correctly, but wasn't taped to the battery like the 2 fatter ribbon cables.
So, I taped it down thinking that me pushing the back panel was moving it and creating a loose connection. I thought I had solved it. Booted it back up, no sound!!!!! Reinstalled the back panel, booted again and BOOM, the sound returns.......
Gutted.
Not sure what to do next, it definitely sounds as if something is disconnecting and reconnecting like a USB on a PC, im getting the sound but no notification or error. I have no idea why this would make an app switch to the previous app or webpage when on net.
Any help would be much appreciated.
Well, it seems I have solved the issue. Since this is a new account, I can't post youtube videos. So I'll leave those out for the time being.
Firstly, heres a video showing the fault. As you can see, I've narrowed it down to the docking station/charger connector.
The ribbon cable was seemingly depressed causing it to disconnect briefly before reconnecting when released. Probably the down side of having a flimsy plastic case.
Solve the issue I removed the ribbon cable and taped a small amount of foam right at the mouth of the connector, making the whole connection sturdier and harder to depress with the cover on, which can be seen here.
Hopefully this helps anyone who finds themselves with a similar issue.

Yep, if the problem isn't fixed there's no way it'll get fixed under warranty now...
If the device is less than a week old, in Oz, the shop is supposed to replace the device immediately. This doesn't mean they won't try the old "It'll take 2 weeks to fix" and "It has to be sent back for repairs" schtick....

[Q] White screen of death?

Has anyone encountered the following issues with their SHIELD?
Mine was working just fine after updating to 4.3 and rooting with CWM. I performed multiple reboots in this configuration, played games, etc. - everything was fine.
I had a pretty busy weekend so didn't touch the SHIELD at all for a few days. When I got back:
When I opened it up, I saw the screen backlight turn on but nothing displayed on the screen. The SHIELD button was glowing green.
I long-pressed the SHIELD button to turn off the device. When I turn it back on, I get a white screen that is dark around the edges (mostly vignetting around the corners). The brightness of the screen here and degree of vignetting seem to change every time I try and turn on the device.
If I enter fastboot mode via the key combo, the same thing happens - white vignetted screen. The device DOES appear to enumerate as a fastboot device on my PC in this configuration.
At one point I figured it might be due to a low battery, so plugged it into the charger. 30 minutes later, when I opened the lid, I actually came up to a launcher screen with 65% battery.
However, after closing the lid and reopening it again - black screen again, with the "white vignette of death" coming back if I reboot.
Has anyone else seen similar behavior? Searching results in no one complaining about a white screen like this, at least not on this device.
Screen of Death
This just happened to me today. Did you find a fix for this problem?

So ive already gotten two shields and they both got the same effect. my guess is the ribbon cable when you open and close the screen, is wearing off? because when i open my shield in a certain way, it works... when i open it at around 100 degrees or open correctly then tilt it forward, the screen tears and slowly shows the white screen. I do admit that i open and close the screen more than i should, but i do it carefully. Ill look over at the ifixit site to see how the cable is connected to the board.
This is what has me worried about buying a shield, the ribbon cable, did you confirmed this was the problem?

I am a tech by trade and bought one of ebay for 40 bucks cuz it would not power up so the guy claimed. After getting it I found the issue was actually the display was not coming on and once it did. Then went out in a few moments. Connect it to HDMI and the unit runs all day of you want to be cabled. ]
So I tore it down and found that the issue is the flex cable. The problem is that the flex cable is part of the LCD and you cannot just replace the cable. Also since the unit is so new there are no sources as of yet to by the LCD from.
So if you have this issue I suggest just holding out till a source of LCD's at hopefully a reasonable price become available.
So it's soldered to the screen and not replacable right?

That is correct.. The flex cable is actually an integral part of the display and even has much of the driver circuitry placed right on it at the LCD. In the business we call it a flex circuit since it is a flexible circuit board and not just a cable.
I pretty much know what you mean.
On my old Archos Gamepad I ripped the flex that connected the left side of the controler to the logic board by accident.
It was a pain in the ass to fix it by soldering seperate wires, I guess it's impossible to do this with the display connection in the Shield.

Might be possible if you used 32 gauge magnet wire. It is enamel coated so it won't short, but it to will break over time.

How are you supposed to flash a factory image when the screen won't let you see what you are doing? When you are in the bootloader screen the HDMI drivers are not loaded yet so not even hooking it to an external monitor will work. You might want to fully read and understand the problem next time before offering advice.:good:
fastboot tells you if you were sucessful or not.
just for relocking the bootloader you have to do some button combinations, you can look up some tutorial videos to see what you have to press.

Even still, it is not a software problem that causes this. I know because if I move my display to a certain angle it will start to work sometimes. A software issue would not cause this. I also have taken my apart since I am a tech and can actually see the traces in the flex cable that have broken..
Any device with a folding display is a bad idea and a failure waiting to happen. Flex cables have a limited number of flex cycles that is even usually published. So the idea of using them in a device that may get heavy use is just dumb.

I agree, they used flex in the Nintendo DS and 3Ds as well, but they don't break that fast.
I find it still better if they have used recular cables like what they use for Laptops.

What you are saying is the EXACT same thing that happened to my SHIELD. I can tell its a hardware problem because when I tilted my screen it would work, and sometimes it wouldn't. Now my SHIELD's display does not even show any signs of picture. HDMI still works, however. Like one of the previous posts said, there is not a screen available for purchase, so my next step is NVIDIA customer support. Maybe if they would sell these screens, I wouldn't even have to have a warranty claim. sigh.
White screen of death?
yes mine too same as
i tried connecting my via HDMI from power cable to large HDMI to plug it works fine on my galaxy tab
thought id be clever try it on nvidia shield never worked sould of bought mini HDMI so now White screen of death
i cant get into recovery or anything i had this on charge for 12 hrs yesterday still no green button on charge only orange .. i too cant find anything on internet to help with this White screen of death situation

This. I'm having a similar issue. My wife's SHIELD has an unresponsive touch screen. So I tried to flash the factory image (It was never rooted to begin with) and I got the white screen issue when in the bootloader screen. I have to keep restarting it to get the screen to show up as normal when the device boots to the home screen. But the bootloader screen is still blank and white. I was able to watch a video and mimick the steps to flash the factory image but that did not fix the issue. It's definitely a hardware issue. I live in Cincinnati OH, anywhere I can go to have this fixed? I have a portable myself and i know this is going to happen to mine soon.

[Q] Snowy Screen (LCD/Touch working)

Hi guys
First of all: SORRY FOR MY BAD ENGLISH...
As you can see in the title, my Nexus 5 (16 GB) is showing a snowy screen all the time. When i turn it on, the display lights up and the phone probably boots. After the while the display is dimming and then turns off (probably lockscreen...). I managed to slide my finger from a corner to the middle, so that i can say the touchscreen is working.
First I thought the screen was defect, so I ordered a new LCD screen. After replacing the old by the new screen I had to see, thats its not the LCD/touch/display what is defect.
So does anybody had the same problem or can tell me what this might be. I'm not even sure if it's the hardware or maybe the software of the phone. But due to the "process I described in the beginning" when I turn it on, I suggest it's the hardware.
If have no idea what happened to the phone and why it isn't working. (I bought it on the internet as a defect device)
I would be very thankful for any answers.
IMAGE: the "NEXUS 5" on the image is a screen protector!!!
When you bought it did they say what kind of damage it had? Like was it water damage? If its water damage then I'd take it apart and clean the board. The board can be corroded due to water dame and/or possibly the ribbon connectors that attach to the screen.

no,... I asked, but got no answer. When connecting the new screen I could see the inside, for me (I have no experiences with that) I looked quite good
I also checked all the connections.

I'd probably take it back apart and clean it with a soft toothbrush and some rubbing alcohol. REMOVE the battery before you clean it or you will be sorry. Then thoroughly dry it with a blow dryer (make sure it isn't set on hot. Warm or cool is fine).
To me it sounds more like a hardware defect rather than a software defect.

Also did you try getting it into BOOTLOADER Mode? The only software defect I can think of is the person flashing a custom ROM/Kernel and they messed with the voltage setting. A low voltage setting can cause the screen to be snowy/fuzzy looking.

hmmm... I took it apart, and blow it up. Maybe I'll be doing the alcohol things in a while.
I already tried getting into bootloader (pressing power + Vol down). But now I tried again:
When I keep pressing the two buttons, the screen is slowly blinking: "snow" --> black --> "snow"... three times, then it comes a short "snow" and then its black and stops.
I don't know what normally happend when you hold the buttons at the Nexus 5. Will there appear something three times and then turn off again when you keep holding???
btw: already thank you for your advices (but if it's the hardware, I'm afraid some chip/processor/...??? will be defect)

[Q] Digitizer is cracked, unsure if I need to replace the LCD as well.

The person who had this device, gave it to me, telling me I could have it but that it had display issues. The display would intermittently cut out. He tried showing me how he would get it to come back on was by, flexing the device... He showed me a couple of times and I thought, to myself, I may be able to fix this. Then on one of the times, he must have flexed it too much because it cracked top to bottom. While it was working, I noticed it did display the desktop fully, leading me to believe that the LCD ribbon may have become unplugged. I was unable to find any information on replacing the LCD for the TF300T on YouTube, so where is it?
Also, the previous owner opened the device and lost the power button, so he would use a toothpick to turn it on. Is there a cheaper option than $11 USD on Ebay?
