My GTab went white today sometime between my 1.75 yo daughter watching sesame street youtube videos and me wanting to check mail. As far as I can tell there was no major trauma (drops, kicks, stabs, etc.) and I haven't flashed anything in weeks. (VeganTab is great eh?.)
Configuration:
VeganTab 5.1.1 + Security Patch
Symptoms:
White Screen under all circumstances, power up, eventually goes gray after about two minutes. No response from buttons other than power.
Removed Micro SD card.
White screen on Power & Vol+ , I don't get the recover screen here
Power & Vol- White screen then black (like normal nvflash mode) so I followed directions for nvflash restore using the bekit image plus clockwork.img instead of part9.img - not my first time using nvflash, it looked like everything went fine., except I'm back to a white screen.
I opened the case and pulled the battery, no dice.
I pushed the button (dunno what that does) the back light flashed, but that was it.
I've run out of ideas, so at this point i'm thinking it must be a hardware issue. I didn't find any similar threads on xda.
Anyone seen this before?
Thanks!
Kyle
I can get a screen image via HDMI out on the base station, so it's got to be hardware. After getting past an e-mail error message with an external kb, I was able to prove that the touch screen does in fact work. Impossible to use w/o a cursor tho.
Any ideas would be appreciated, otherwise I'll have to call Viewsonic Tech Support on Monday.
Thanks,
Kyle

Had the same issue while playing angry birds. I am pretty sure that it is hardware related so I returned my gpad.
Meh, I was afraid of that. I'm past the return date on mine- got it in November I think. I just ordered a B101AW06 off the bay, I figure I'd spend half that on shipping the gTab back...

The other day, I hit the power button on my touch pro, and the screen didn't come on. I did a soft reset, and it started working again. Now today, the same thing is happening, but a soft reset isn't helping.
The screen's back light comes on, the LEDs on the buttons come on, and the phone seems to be working fine. I hear all the sounds, including the HTC sound while it is booting, and the new message sound, but the screen stays black. It still recognizes touches, it just doesn't show an image. I want to do a hard reset, and will if I can get it to come one one more time, but its been about a month since I backed up my contact list. Lesson learnt there. I'm afraid it might be a hardware problem since I don't see anything while its booting either.
Anyone know if this is a known hardware issue with the touch pro? The phone is less then 3 months old, and I've been real careful with it. I haven't dropped it from more then 2 feet, and even that was onto carpet. Its the Verizon version if that makes a difference, and I'm running one of the NFSFAN roms. Its not the newest one, but rather the one posted on October 19th. I doubt its the rom, though, as I've been using it for around 2 months with no issues.
EDIT: Ok, I went into the bootloader to see if it was hardware of software. I figured if it was hardware, the screen would be black, and if it was software, it would be the rainbow. Sure enough, the screen stayed black. Hit the reset button, and the screen actually came on! Go figure. Went to do a backup, and the screen literally crapped out on me while I was watching it. Definitely a hardware problem.
similar with Touch HD... kinda
I've been having a similar problem with my Touch HD. The problem is very intermittent though and is sometimes hard to reproduce. The screen and phone will be working fine then once in a while when I push the power button to lock the phone, I'll unlock it and the screen stays black. I know that the phone is still on and even unlocked because pushing the buttons at the bottom makes the phone vibrate. The only consistency in reproducing the problem happens after I do something major on the phone such as making a phone call, browsing the internet, sometimes charging the phone. Other than that, I can sit here and push the power button all day and it'll come on and off with no problems. When the screen does go black I've taken the battery out repeatedly as well as repeatedly rebooted the phone until it comes back on. I've tried doing hard and soft resets to no avail. I've tried deactivating "turn off backlight if device is not used for" and "turn off device if not used for" without any resolve. After this I've even left the screen on (disabled backlight off) to see if it flickers or shows any sign of being faulty and it seems to be fine. I'm currently on Dutty's HD WM 6.5 Leo R5 WWE rom, but this has happened with two other roms (NRG, LIA). Other info include:
OS: 5.2.23016
Manila: 2.519192828.0
Radio: 1.14.25.24
Protocol: 52.64.25.34H
I guess the only consistent software has been my radio. Please help! Any advice would be awesome. I've tried google search and xda search without much help. Thanks
So I've had the G-Tab for a month now (stock 1.1) and decided to change the rom to Vegan-Tab and followed these steps.
1. Installed CWM fine no problems.
2.Repartitioned, again fine no problems.
3. Tried installing Vegan-Tab appeared to work fine until after re-boot the tab got stuck on the three birds.
4. Realised I should have run NVFlash before installing new Rom so ran NVflash, again appeared fine until re-boot. This time I was not able to turn the Tab on (Power Button not working)
So now the only way I can turn on the device is to run NVflash (tried with and without CWM) and leave it on all day.Power button works fine for entering sleep mode or for turning Off but just will not turn the Tab on. Any time I try to install a new Rom I get through all phases until the re-boot, then nothing. Guessing I am maybe stuck in APX but how do I fix?
Yes... you're in an APX loop. Try the following...
1) Do an nvflash to start it up and immediately do a datawipe. If the resultant restart doesn't fix it...
2) Goodintentions has a GTablet for Dummies website with known good nvflash images. Follow his instructions carefully.
3) If none of that has worked... Sometimes the only way out of these loops is to force the tablet to reload a stock bootloader. The following procedure will do that:
http://forum.xda-developers.com/showpost.php?p=13474033&postcount=114
This guy has already tried all those tricks. I was the one who sent him here. Anyone else know how he could fix his gtab? I ran out of ideas.
If that's the case I'd be interested in seeing it. Ive never seen one that failed all of the above... Perhaps a hardware problem?
Logs would help...
Any error messages during nvflash?
Any other odd behavior?
Be happy to help if you can supply more info.
Hey, yo, try my new code detox in the home page. Can't believe I forgot about that.
http://viewsonic-gtablet-for-dummies.webs.com/
Thx for your input guys, especially goodintentions. Ended up contacting Viewsonic and sending unit back. If they repair/replace it great, if not and I get it back I will try your detox. Either way next time I will follow your directions to the letter and won't get carried away this time. I will also be sending a donation/beer money your way! You guys are great for us dummies.

Will VS replace the unit even though you flashed a ROM to it. I was wondering if I should send mine in. I NVFlashed it and now I get nothing. no screen, no recovery mode, no APX mode. It is not recognized by Windows when plugged in nothing but that little red glowing light when I plug in the power jack.
If you can't turn it on, then they can't turn it on.
I'm guessing what you have is a hardware issue. Just a coincidence that it happened as you flashed in something else.
After updating to 3.2, I noticed that the touch screen has a ton of bugs. I used this program to check the inputs (I can't post links now due to forum restrictions):
Multitouch visible test
Basically if I scroll from far left to far right (Asus logo on the top left of my view), there is always a cutoff somewhere on the screen.
I never or hardly ever notice this problem when I'm in 3.1.
Any ideas on how to fix the problem? Or is it just 3.2 that has this and I should go back to 3.1?
Help is totally appreciated. Thanks!
Update:
Sent in the TF to Asus (to Ontario Canada) on August 9, 2011
Received it back from Asus on August 29, 2011 via UPS
Problem: they only reloaded the OS and did NOT test the touch screen so I have the exact SAME problem... Requesting RMA again
Can you grab a video of the issue?
Plonk it on youtube and then stick the url on here.
Cheers
Video is at youtube:

Basically a portion of the screen does not respond to touch, and the classic turning screen on and off does not fully solve this problem.
had this problem before 3.2.
my screen have only small places..quarter of inch, random places.
noticed this only after rooting. and with some kernels more than others.
have you rooted?
No root. All stock since I am too lazy to do anything other than install apps, view video and manga.

Quality vid there, top notch.
Have you tried a hard reboot?
And a restore to factory default settings?
For some reason that sounds sarcastic there... but the video was taken by a Desire HD so it's not that good quality. It conveys the point (I hope).
Haven't tried hard reboot or factory default settings because that would mean I have to reinstall stuff and re-setup things like gmail.
Lol dude, i wasnt being sarcastic, for some reason i was expecting some half-assed effort.
Hard reset shouldnt wipe your data.
Hard Reset:
Unplug the power cord and shut the unit off and Press and Hold the power button and the "Down" volume button together for 6-10 seconds and let them both go. After a few seconds you should see a couple of shapes in the middle of the screen called "Wipe Data" and "Android". Wait a few more seconds until the term "Cold Boot" appears in the list near the top of the screens and just press and release the "Down" volume button again and let it reboot. If you own the dock be sure and do this with the dock connected.
Sorry man, I guess my sarcasm detector is pretty off today.
I tried the hard reset and the same problem persists. I will have to see how this can be fixed though (I see that many people have similar problems though).
Thanks for your help =)
might be worth giving asus a tinkle and see what they say.
TL: DR: Screen sometimes is totally black, but otherwise the screen seems to work fine. Sometimes the phone acts completely normal. Sometimes the phone acts completely normal, but the screen is tinted green, but only after it's booted up. I can access download screen with no issue, most of the time I can get into recovery with out a problem, but not always.
I'm brand new to the GS3, but I purchased it last week on ebay (described as fully functional) since my other phone has been giving me troubles. I received it last Thursday (5/15/14), and it seemed to work fine. I have not been able to activate it yet since I did not have 4G sim card, so I've just been playing with it around the house to make sure it works until I get my 4G card from Verizon in the mail.
So Saturday comes along, and I notice that the screen is all black, but makes the usual sounds when you touch the screen. I pull the battery, and boot it back up. The Samsung logo would come up, but none of the boot animation. Nothing after the Samsung logo. It seems that if I push the power button, the phone seems to be functional, but nothing comes up on the screen. Sometimes if I push the power button a bunch of times, I can get the screen to come on. The screen looked normal, and everything worked fine, until I hit the power button. Back to the black screen. I booted into recovery, cleared the cache and did a factory wipe, and it seemed to be completely normal for a while.
I've noticed that sometimes phone acts completely normal (proper colors, screen turns off and on as it should), sometimes it works normally but the screen is tinted green (power button turns off and on the screen as it should), and sometimes, the screen is totally black, but the touch functions work normally.
Since the screen always works at boot (I can see the Samsung logo clearly and with no color distortion, but sometimes the rest of the boot animation is gone, even though I hear the boot music), and there is also no color distortion in recovery or download mode, am I likely looking at a software issue?
It is not rooted, and completely stock on 4.1.2. EDIT:Baseband is VRBMF1.
I have tried to make my problem as clear as possible, but I will clarify anything if necessary.
Thanks.
I downgraded to VRBMB1 with ODIN, and I still seem to be having the same issue (screen goes black, won't come back on), although the green tint problem hasn't happened yet. As long as I leave the screen on, it works fine. I'm thinking that this might be a problem with the power button, although I don't understand why it would allow me into download mode with no issues, but trouble doing much of anything else. I'm probably going to be sending it back for a refund, but if anyone has any suggestions, I'm more than willing to listen. Thanks.
Situation: Samsung Galaxy J7 Crown. Never messed with. USB Debugging not enabled No special permissions (no ADB). I am able to access the Android Recovery screen. Obviously wipe cache partition didn't help, nor Lacking storage booting. Other than the Recovery and download screen: I get the Power/Restart icons when booted normally. Reset works, but power doesn't turn the phone off. No phone calls, Yes notifications. Camera from lock screen comes on (triple click on home button) and touch screen works.
I've tried to trace out the lock pattern in the hopes its still working outside this specific situation. No indication that it is.
All i want is a few sentimental pictures. Although after an entire day of frustration, finding out that the only thing that works is the camera is kinda funny and ironic.
Ive looked on XDA forums, but I'm having no luck w/ exact situation, although I'm sure someone has been in the same situation or similar enough.
Spent all day looking at options (Odin?) and nothing looks like it would work out for me.
Knowing the camera works, makes me hopeful that a mirror would work? No reaction to lock screen pattern makes me think not.
Additional (maybe irrelevant) info. Shows up on home WiFi while Find My Mobile said it was offline (makes sense with Notifications/no calls)
Any advice? Just point me in the right direction if there is one.
If not i hope you appreciate the Irony here. Thanks
(I used to be not so bad tech support, but haven't been keeping up as of late, and today was a painful reminder. Take pity on me.)
Black Screen Except Camera - Galaxy J7 Crown
Hey there anick22! I was so glad to see a search result with something referencing the camera working, on an otherwise completely black screen! I was super bummed to see that noone had replied to your plea for help with this insane problem!! I hope you found a solution by now!!
My 2 month old Galaxy J7 Crown suddenly went black on me one day, and it didn't happen as a result of a drop, or spill, or any other damage. I don't recall having put any new or different apps on it, recently, either.
The triple click of the Home button does open the camera, and the screen lights right up, perfectly. It takes it's usual beautiful pics, and I'm able to use all of the camera functions. I'm even able to view any photos I took during that particular session, buy not any prior pics, because I'm unable to unlock the phone.
"Hey Google!!" also reacts, and will display the result of any question that I may ask it, but I'm unable to go into the answers, without the ability to unlock my phone.
I have been able to get the phone into safe mode, while attempting to power it off, by pressing the power button, and then tapping on "power off" (although this hasn't worked every time I've tried). While in safe mode, "safe mode" is displayed in the bottom left hand corner, but nothing else appears on the screen.
Upon powering up the phone, all of the normal things happen. It shows "Samsung" and goes on to the blue screen to show the "Trac Fone" logo, but once the phone is booted up, the screen is black!!
PLEASE tell me that you were able to find a solution to this!!! I went and purchased a new Moto G7, (since I had a Droid Turbo 2 in the past, and it was amazing!!), and I'm beyond ready to get back to my J7 Crown!! PLEASE HELP!!
Thanks so much!!!
By the way, I'm a newbie here, as If you couldn't tell!!
