Hello everybody,
I was playing a game on my device, the EM ONE, and I had to leave the game running for a while - it's the Bejeweled 2 game. After a few minutes the device went into suspend mode, switching the screen off.
When I tried to start it again, the screen remained dark at first, then, after 5-7 seconds it started lighting up slowly, like individual pixels were lighting up little by little until they were all lit (like stars appearing in the sky).
However, the screen only lights up to white and nothing else. I tried resetting, switching on/off, eventually I attempted a hard reset. Still the same thing happened - the display would gradually light, and then just stay in white...
time to call the warrenty depo
Yeah, wish I could. Japanese devices don't get support outside Japan.
Anyway, by the looks of it, I am pretty sure it's to do with the nVidia GoForce 5500 chip. I know little about PPC hardware so I don't even know if this chip can be fixed somehow, or the only "cure" is replacing it - in which case it gets all too expensive and pointless.
No idea how, but as I powered the device today to take pictures of it to post in a forum, it powered on perfectly normally.
Played with it for an hour, then shut it down. Trying to power back on in a while resulted in the same blank screen I described above.
While in this state, I launched the TCPMP (with one of the hardware buttons) and it started playing - I could only hear the sound....
EDIT: I found out that if I put the device in the fridge for 20 or so minutes, the display will light up normally and will work until I suspend the device. After that, if it's heated up, that is, more than 10 minutes have passed, it will again show the white blank screen.

I had a weird instance happen on one of my pros a little bit ago. I hope I'll be able to explain this well enough for someone to recognize it (i'm pretty tired).
I was charging my pro... i disconnected it from the usb, then went to turn the display off via power button and my screen turned black. Not off, but black. Even in this black mode, you could see fuzzy lines so it was obviously acting strangely (picture an old tv on an input channel not being used. Youd be able to tell the tv was still on...). The phone still functioned, i just couldn't turn the display off at all no matter how many times i pressed power on/off (I'd only get the strange fuzzy black screen). A soft reset fixed this right away... I just think it's weird that it would still acknowledge my power button presses by turning to that black screen... why couldn't it just turn off if it was acknowledging what i wanted?
Has anybody ever had this happen on any of their phones, present or past? I'm thinking this is just an isolated incident, but i'd like to know how rare of an occurance it actually is...
i'd hate to think i'm the only one that this has happened to.
I've had this same problem -- and so is a coworker of mine who has the same phone... we're running Juggalo's 0.06B ROM.
AT&T Fuze screen issue - bottom menu-area of screen is flickering almost constantly
(Forgive me for the length of this post. I am just trying to provide as much information as possible! If anyone has encountered this same or similar issue, your help is greatly appreciated).
I need help! (professional and otherwise) ...with my AT&T Fuze (rebranded Touch Pro).
I am developing a game for Windows Mobile called Scrobble (http://forum.xda-developers.com/showthread.php?p=3206316&posted=1), and I left it running overnight.
My screen is set to turn off after 1 minute, and my device set to sleep after 5 minutes when plugged in to external power.
I had the Fuze plugged into wall outlet power to recharge. I left it lying, like I always do, face down on a black soft-leather CD case (so the glowing charging light doesn't bother me).
I left it alone for the 7.5 or so hours I was asleep. When I woke up in the morning and picked it up, the screen was on. It usually is not on, and I don't think I pressed the button to activate the screen.
When I looked at the screen, the Scrobble program was still running, and the bottom menu portion of the screen was flickering. Scrobble has two menu buttons at the bottom -- "Turn" and "Game" -- with a SIP keyboard icon in between them (same as nearly all WM apps).
In any other program, or the Today screen, the menu portion of the screen flickers (the brightness constantly and rapidly fluctuates consistently... like a fluorescent light that is on its last leg).
I did a full power off and power on, and during the "world phone" screen and the the AT&T 3G "power up" animation, the flicker was -not- there. But as soon the Windows Mobile loading/splash screen appeared, the flicker returned, in the exact same spot.
And I can see the ghost "Turn -- [SIP] -- Game" menu in the flicker. But I don't think it's burnt into the display, because it's not there during the first two loading/splash screens.
Currently I have the battery completely removed from the device and will leave it out for a while. If that doesn't work I will do a hard reset.
Any help would be greatly appreciated!! (This device is about 2 months old -- does HTC provide any support for it directly?).
Fixed
Phew! My screen flicker issue is no more.
I'm not sure if it's because I took the battery out and let it sit and think about what it had done for ~22 hours, or if it's because it just went away after a while (with the battery out for 22hrs). But either way, my Fuze is back to normal!
So if anyone leaves theirs on overnight and wakes up in the morning to a flickering ghost of a menu at the bottom, my suggestion is to fully reboot it, then take the battery out and leave it out overnight!
(It's kind of nice going a full day without any phone calls!!).
good for you.. you dont need a new phone giving you damage issues already... glad to hear that its gone
Thanks you for this post. I am going through the same thing with my ATT Fuze. This time it is Tomtom that I left running overnight with the screen turning on and off. I can add that the flicker and ghost is there the second the phone powers on. I have already hard reset and took the battery out for a few mins, but the flickering still there. Now I will take the battery out for several hours and hopefully it will be normal again.
I had a similar issue this week. I was using the phone all day, getting emails and phone calls, no problems. I get home and go to charge my phone and it doesn't appear to be charging. I flip on the screen and the whole screen is flickering on and off like it's not getting enough power. I charged the device over night, hard reset, pulled battery for 24 hours and still it won't go away. I just got the device thru amazon so I already reordered a replacement.
I've never left my screen on for hours at a time and I sometimes run into that same issue. The bottom of the screen flickers, and I can see a ghost image of my left and right soft keys when doing things that pull up a dark grey or black screen, like adjusting the volume. I usually try a few soft resets, and if that doesn't work I turn it off and take the battery out for a while. From what I am reading it seems to be correlated with extended periods of screen usage, but my screen has rarely been kept on for more than 30 minutes at a time.
Not to beat a dead horse or anything, but I was just having the same problem with my Fuze: the bottom quarter of the screen was flickering, but without the ghosting you spoke of. Out of curiosity, I went into my "Power Settings" menu, and for some reason the "auto adjust backlight" was unchecked, and the brightness settings were maxed out. I checked "auto adjust backlight" and the flickering stopped. Not sure why, but thought I'd add it to the thread.

Yeah I did notice that it's only really noticeable when the screen is set to max brightness. Setting it on auto adjust cleared it up for me also.

thx guys...helped me out too...
Just sent my unit in for repair (under warrenty) due to the screen flicker issue, lets see what happens when it comes back.
I just started to experience the flicker today. Has be somewhat concerned. The device is only two weeks old.
However, it seems to have stopped by itself while I was searching the forums for an answer. If it returns, I'll try the 'remove battery' method and see if that helps.
Also, I love Scrobble! Shame it doesn't work on QVGA displays. Or, at least, didn't on my Wizard...

Hey guys there's a thread with the same exact issue and a screenshot on the first post.
http://forum.xda-developers.com/showthread.php?t=535099
Seems to be something related to the Hardware 3D Acceleration driver for Windows Mobile, I get this problem only once 3d has been activated.
If Sense/TF3D is turned off, I never see this problem. It only comes up once a game or Sense has been launched.
I can also boot into Android without 3D activated and not have this problem, but if I run Sense then go into Android I get the flicker from a Windows Mobile screen while in Android.
protwitness: That doesn't seem to be the case (for me, at least.) I don't run TF3D and it still happens. I can't really discern what the trigger is, but I have a feeling it has something to do with the screen brightness auto adjustment. (Sometimes, I'll turn my phone on when it's dark and it jumps to full day-light brightness for some reason.)
I've adjusted to it and it doesn't really bother me any more.
Hi guys, hope someone can tell what is exactly with my phone/display.
Long story short – phone fell directly on display, absolutely perfect landing without any rebound, display went nut. Dropped it on back, fixed the problem.
4 days later, display went crazy again and remains broken.
Symptoms: black, grey, coloured lines.
What I can say from usage – they react more on dark colours. If I’m in white background, everything is absolutely fine, sometimes some line appear. As soon as it comes to grey or black, they go wild. They like move for second or two, and then settle, as you can see in the video.

LONG STORY LONG
Seven days ago, it dropped from 1 meter height, and it landed on it’s display, so directly it didn’t bounce not a tiny bit, it just got like glued to the surface. The same moment I knew it’s not good, and I was right.
Display couldn’t get out of sleep mode, when I presed power button I only got a bit of visibility, I could see start button, but if turned it on/off (sleep/wake up) couple of times, display would have normal brightnes… BUT, there were some dark dynamic lines over the screen, as soon as pic moved, they would appear, on static pic, only few would remain. Numerous resets didn’t bring any results, keeping it off without battery, no results either…
Frustrated (It has been like month or two since I’ve got this device), I decided to give a try to traditional Serbian method – hit the electronic device to get it working. I included some brains, so I dropped phone, on the other side (on the back), from some 30 cm height. It worked like a charm! Everything worked absolutely fine!
I could only think of situation that some display contacts must have pulled out a bit, so hitting it back, made them get back into their slots.
And everything was like before… at least for 4 days
Then, without any trigger event, lines came back, and they’re here to stay!
Hard reset, nope. Reset, nope. Dropping it on the back, nope.

There is no one here to make good diagnostics, HTC is like white raven in my country, so can anyone suggest what to do, get new flex cable, get new display?
I am considering opttion to open it up myself, and check are all connectors firmly in place.
Your suggestions?
If anyone experiences anything similar - just reset the flex (flat) cable, everything will be like new
My friend smashed the screen on his nexus 5 and gave it to some shady repair shop. They replaced his screen (with a white one, on a black phone btw, now it has a white dot on top) and he paid a lot of money for it, but now his display won't work, so he gave it to me to fix, as I have some experience with fixing phones and he has no money left. The repair shop refused to take it back and he doesn't want to start a legal battle. As far as I've tested, the phone shows three behaviours. The first is that the phone boots normally, but without displaying anything. I can still hear it getting notifications and can connect it to a computer, it's just not displaying anything. The second behaviour is identical to the first, except instead of a black screen the phone shows colorful static which seems to correspond to screen-on time (when I lock the phone it goes black and vice versa). The third behaviour, which is the weirdest, is that the display works, but everything displayed is glitching. The google logo maybe has the top 20% moved down a bit, the boot animation may be choppy or distorted, the recovery menu may be divided into blocks which are moved around a bit. In this 'mode', I have never gotten it past the boot animation. The reason I wrote 'may' is because it's different every time, but eventually it always just goes black and stops responding until i disconnect and reconnect the battery.
I opened the phone and fiddled with the connectors a bit and found out that pressing the usb board connector to the mainboard seems to cause the phone to switch between these behaviours. I took a small piece of paper, folded it over a few times and put it on top of the connector and then screwed the cover back on to hold the connector firmly in place. That seemed to put the phone into constant behaviour 3 (graphical glitching).
What could be the problem? I know that the static indicates that the usb board or more probably its connector is faulty, but I'm more concerned about the glitching. It seems to me that the graphical processor is malfunctioning, but I have very little knowledge about graphical processing and displaying so I really don't know. Any help would be greatly appreciated.
UPDATE: the phone just did something weird, when I turned it on it displayed static, but then it started drawing the boot animation slowly from top to bottom. And then proceeded with behaviour 3 as usual, the animation ran at about 3fps and just went blank after 10s.
Okay, I have located the exact location of the fault, the USB board ribbon cable that goes over the battery was bent at a sharp angle and then apparently straightened again. If I press it in that point, the screen switches between static and nothing. I have not been able to recreate the glitching since I cleaned all the parts of the phone with isopropyl alcohol. Still, I'm interested in an explanation to avoid further problems with glitching
now it's behaving even more strangely. When I turn it on, it slowly fades from grey to bright white screen and then goes black and starts blinking a red light. What does this mean? Please help
anyone?
The first day allready 2 times black screen out of no where and afther that no reaction on any buttons.
The first time i waited 10 min or more then the S7 reacted normal again.
The second time i pushed the buttons....
The only reaction is when i press the same time: powerbutton, homebutton & volume button down.
Has anyone the same problem?
I had that issue once with the home button. I had to schedule a reboot through the craptastical built in scheduler that is says it is supposed to optimize the device. Search for restart in the settings.
I have the same sort of problems. All in all the s7e seems very buggy to me. Random crashes (especially in oculus app), sd card is sometimes not recognised and after most reboots I get two error messages (one about touchwiz and one about system proc). I'm not sure what is going on.
My wife's is a black too. I had a similar issues with my s6 last year it was the brightness had been swiped to low in my pocket, I was able to barely see the screen in a dark room and turn it up. No such luck with her s7. Hope someone can offer an idea, I'm headed to Verizon later if I can't fix it myself.
S7 black screen
Verizon did a reset for my wife's S7 to fix it hold down volume down, right side button, and the button on the face of the phone together for 15 seconds. The phone came right back on with all apps and stuff intact. Hope this helps, they said this wasn't the first S7 to come back like this they think it's a software glitch.
Im having the same problem....
any one having dead galaxy s7 edge not broken

Try turning off the App Power saving mode!! This fixed the black screen problem on my phone.
I've got the same issue (sometimes 4 times in an hour, sometimes it doesn't happen for 2 days..!!).
I've tried fixing by doing a factory reset and turning app power saving mode off.
Unfortunately this did not fix the problem. Yesterday I got an unresponsive blackscreen again :crying:
Any ideas how to fix this problem?
This happened two days ago with my wife's S7 Edge. She was using it to text me about dinner plans after work, her screen shut off, and it wouldn't work for several hours. The thing was getting very hot. When she was home and charging the phone the screen started working again for a little while, but with several green stripes down the right edge snd aa flashing horizontal band of grey near the top overlaying the screen image. Then when I tried plugging it into my computer to use Samsung's Smart Switch to roll back from the update she had accepted while at work the screen died again. It has not come on since, not even the stripes, and blue or red LED lights once in a wwhile at random. I managed to use Smart Switch to wipe the phone's memory. Then the program took several hours to download something very slowly and install that - a whole new OS update? That completed, and now the charging LED works correctly and the green stripes and grey band are back, flashing rapidly when powering on. Otherwise no screen function. She is shopping for a new non-Samsung phone now. Ridiculous.
