Att Fuze black screen need help please! Not a bad flash issue.

Hi all,
I am at my wits end on this problem if anyone can offer any adivice it would be greatly appreciated. So let me give a recap of what has occured thus far. The water damage tag for some reason turn pink thus i am unable to get warranty exchange. I am pretty certain that the phone has never been expose to any water of anything of that sort, but i do live in houston, tx so might be humidity or what not that cause the tag to turn. Anyways.
1. This all started after i flashed RRE 5.2 RC3. Initially after a successful flash everything seem normal and fine. Then next morning i woke up to a frozen screen with many verticial lines running up and down the screen was almost unreadable. Initially i thought it was a bad flash or just random lock up. I did a hard reset and tried to enter the bootloader. Black screen, it does seem like the backlight is coming up but nothing on the screen. I can hear the phone power on and boot successfully into windows. Activesync connects i can browse the contents of the phone.
2. After flashing to stock att rom and stock htc roms same symptoms. So at this point i am thinking crap bad LCD screen. so I ordered both the digitizer and lcd screen for good measure. I replaced them hoping that a bad LCD was all. replaced both screens and i powered on the phone. same problem. black screen. The phone still powers on and boots into windows. Activesync still connects and i cna still reflash the phone.
3. I work extensively and do both desktop pc and notebook repair. I am not new to dealing with small electronic repairs. but at this juncture i am unable to identify the cause of hte malfunction. i am hoping maybe some of the gurus here might be able to shine some light on the subject.
Thanks in advance for any help.

I would have followed the same approach; your description makes it sound like it might be some kind of backlighting issue at first read. I'm inclined to think it might be a cold connection (bad connector) on the main board.
Silly question, what happens if you power up the phone with the keyboard exposed?
*EDIT* Not sure if you have been here yet: http://www.mikechannon.net/
Cheers,

i just tried to power up the phone with keyboard exposed. Powers up the same as with the keyboard hidden. Still boots up fine but black screen. I already have the service manuel dowloaded. i have checked around with several repair places both local and on the web. Seems like no one has any parts for the att fuze/touch pro gsm except for the lcd and digitizer and a speaker.
its quite possible that it is a main board but as the same time it might be something as simple as a ribbon cable. i have contacted htc about doing a possible repair and they want wayyyy too much for just a main board repair almost $400 USD.
Anyone have a bricked/ non working touch pro they would like to sell ? =P

Could be a bad ribbon cable ... and firmly pressing around the front/back of the unit shows no change?

pressing the phone front and back show no changes to display. in a very dark room I can see that there is light emitting from the display but its just the screen is not displaying anything visable. this occured both before and after i changed out the screens. I'll do another visual inspection of all the boards to see if there is any bad resistors burnt out circuits etc.. but i didn't notice anything mentionable during my first 2 inspections. Maybe 3rd time is the charm.
Thanks for all the feedback thus far Hilaireg it is quite appreciated. All this venting has at least made me feel 1000% better than after i replaced my lcd and still same problem at least i don't feel like a complete idiot!

Sorry I couldn't be of much help ... you've done all the steps a seasoned hardware person would do.
Do post back to let other folks know if you get it back up and running.
Cheers,

you have a pm fkoong.

I have possibly the same problem. Phone got wet, dried it out for 2 days (in a container of rice). Phone worked but had "water marks" on screen that disappeared after two days and everything was fine for about 2 weeks. Then one day (happened to be humid misting rain eve in Charleston) the screen is blank (hint of backlight only). A soft reset and it seems OK for about 1hr, then blank again. The hard resest screen displayed OK (readbale text etc), but didnt work. But as I write this, I retry to document it results correctly and the NATF ROM is reloading and the screen works! We will see how long!!
Well.. not that long, the end of the ROM load and it went blank again, seems like a video driver problem. The Press VoluP to boot does show some red artifact.
Trying hard reset again (No SIM no uSD)
The NATF v4.4 loads and gives me the Tap screen, Align Screen, stylus, loads customization, opera, tf3d, then loads a bunch of files under ...... and then the screen goes blank again, seem like what happened last time, so Ill try loading a fresh ROM copy... later

[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.

Phone screen won't come on!

I'm not sure if it's lag or what, but my phone screen won't come on. I think it's a ribbon that was disconnected or something though. For about a few hours if I were to press power to see the lock screen, all I saw where a bunch of rainbow static. Then I powered my phone on and off because nothing would work and now it's jut black! Does anyone know what's wrong? I can't boot into clockwork so I don't think it's a rom problem. Does anyone know the problem or have any idea to fix? Anyone I should ask specifically?

maybe water? even having my phone in the bathroom while i take a shower cause me that

It's not water, I never bring my phone close to place with water :/

can you boot into the screen where there are 3 droids with the skateboards? (i not sure whats the name)

I think I can boot and my phone still works, because it still rings when someone calls and it still vibrates when someone text it, but I just can't pick up or reply (because the screen won't come on). I should be able to boot into that thing, but I can't anything :/

well bro sorry i cant help you :/ maybe it could be the screen,the ribons or somethings loose. did it fell?

Seems like either broken ribbon that connects the screen to the "motherboard', or dead screen itself. That's exactly how 1 of my phones died (it was too complicated to disassemble and fix it myself)
But once I had similar problem with my TP2, the screen first become unresponsive to any touch, and then it went just black after restart (and every next restart). However all keys did work.
Hard reset somewhat helped, the screen actually came back, but it was still stuck on setting up Windows Mobile (if you know WinMo: the part where you calibrate touchscreen), apparently "touch" part of the screen didn't work.
I thought it is ribbon or screen assembly, but since all the keys worked I flashed another ROM and what do you know: all problems went away. It worked fine for as long as I had it. I never figured out what caused it/was the problem.

Yea I think that's the problem here. I think I'm just going to borrow a friends mt4gs to use and navigate recovery and do a back up and just buy a new one and restore. Thanks for all the help guys

G2X Doesn't Power On + Additional Problems

Hi,
I had a G2X which had its LCD screen and the touchscreen digitizer broken about 8 months ago. At that time, the phone would turn on, I could see some colors and through the broken LCD screen I could see that the phone would also go to recovery (I was trying to wipe data if I wanted to sell it for parts).
Now, I tried to turn it on (after charging battery) nothing happened. I could feel the phone and the battery get hot but no screen flickering or anything.
I decided if there is something I can do or try before I just toss it out.
So obviously, I don't have a screen to see whats going on and the only indicators that phone responds is the LCD backlight coming on.
I tried to recover via : One Click ClockworkMod (http://forum.xda-developers.com/showthread.php?t=1056847). Computer indicated everything went smooth. However screen wouldn't still show any signs of life.
I followed up by searching the forum. Found this: http://forum.xda-developers.com/showthread.php?t=2015830, and proceeded to do what was prescribed here: http://forum.xda-developers.com/showthread.php?t=1590523
No life in the phone once again.
I finally tried : http://forum.xda-developers.com/showthread.php?t=1248644 (Computer indicates it was a success, the broken LCD screen was on while the "magic" was happening, followed by 2 flashes (each lasting about 2 seconds) and then nothing. )
I tried to turn it on with battery in: nothing happens.
However when I take the battery out and plug in the USB into the computer, Press Vol- and Power simultaneously: the screen comes on for about 5 seconds then turns off, followed by a single flash of the home and menu keys.
I'm not sure if its a software issue or a hardware issue. I would like an expert opinion from people here in the forum. Should I purchase a replacement screen and a digitizer? to try and see what happens next? or should I just stop tinkering with things I dont fully understand and get rid of the device?
Thanks for any advice or comments

Well if it were me, your going to have to open it up anyways, so pull up a disassemble tutorial video on YouTube, open it up and give everything an inspection for any physical damage.
I'd use a magnifying glass and look for any signs of hairline cracks in the motherboard.
It really does soumd like the screen finally died and that the motherboard is functioning.

Screen randomly turns off but phone still on, backlight often stays on

Hey guys, i'll try to explain the situation as best i can below, hopefully someone can work out what is wrong.
My phone is about 16 months old. About 2 months ago i dropped it twice within the space of a couple weeks. There were a few cracks along the screen, however it wasn't very noticeable and i wasn't going to bother having it fixed. The problem started a couple of weeks ago when i went to grab it out of my pocket, however i found out the screen was black and it wouldn't turn on. I don't really know how to describe it but it was acting very strange...
- The screen would have white/gray bars all over it then turn off, then it would do the same with very thin vertical lines that were white/gray/other colours...
- When i get the screen on, it generally turns off again within 30 seconds, however it can stay on for a few minutes.
- If the screen is on and i press the lock button, it almost certainly won't come back on.
- Restarting the phone or holding the power and volume button nearly always gets the screen to come back on. It often then restarts but turns off again shortly after.
- The phone is otherwise still working when the screen goes off; the notification light stays on and i hear messages etc coming through
- The backlight often stays lit, revealing a gray screen opposed from total black. Sometimes it does not stay lit however.
- When the screen came on it was often unresponsive to touch
I had the screen replaced yesterday by a phone repair shop and the phone is still not right. I have factory reset the phone and also wiped the partition cache. Other than that it is still not working. IT seems to be working better... The screen always seems responsive to touch when it is on, and it doesn't seem to be turning off as often. It generally starts up and works fine when i start up by holding the power button and down volume button together... However even still it sometimes just flashes up with a few thick white/gray and black lines on the screen..
Does anyone know what can be causing this and how i can resolve it? If you need any more information please let me know and i will try provide it. I could try get some pictures of what the screen is doing when i finish work. Thanks guys, i appreciate any input.
EDIT: I managed to get a pic of what i mean by the thin vertical lines all over the screen. This just appeared when i tried to restart the phone after it the screen had once again stopped working. The imgur link is gIFMGD6

Anyone have any ideas?

Hey, did you ever figure this problem out? My phone just started doing the same thing. Can't find much info about it.

Yeah, i had the screen fixed hoping it would fix it, however that didn't work. Turns out it was the motherboard, don't know what was wrong with it in particular other than it was simply going faulty. Had someone replace the motherboard on it for $50 and have had zero problems since! Hope that helps you.

Thanks for the response. I tried replacing the screen too with no luck. Unfortunately the same place that replaced the screen said it would cost $400 to replace the motherboard!!! The phone cost less than that so it looks like I'm gonna buy a new one.
