Hello all,
I have HTC Tytn for 4 months now and have no complaints so far, but lately I'm facing some strange screen problems. Once a while a screen becomes dim or totaly white, and when I turn off the device and turn it on again it stays white. After some repetitions of this procedure it becomes normal again. Even if I make a soft reset of the device, it stays white sometime.
I attached two photos to show you a screen, which is corrupted (screen_02_s.jpg), and the normal one (screen_03_s.jpg).
When this problem occur, the device works OK: I can do a phone calls, listen to music, ... Another thing is, that when I use a Pocket Controller Application, which is used to display mobile device screen on the desktop, I can see the normal screen on my desktop PC, even though the screen on the mobile device is white.
I've read a lot about screen alignment issues and I don't have any such problems, which are reported in the forums.
If you have any ideas how to solve this problem, please help.
its seems the LCD is faulty (hardware problem), I would claim a warranty replacement. I dont beleive software will cause such a problem.
By the way, how was the basketball game on Wednesday?

Hi mates yesterday i bought a used herm...with excellent condition. but when i opened any dialog. the window closed automatically. and the screen light remains always on. and touch is creating problems.
and after some time the touch screen totally stop working. i dont know what happened. al the buttons are working fine. i upgraded my t-mobile herm to its original t-mobile wm6 rom. and again the touch screen is not working. and the screen light always stay on..
so is this hardware or software problem.?
guide me if you have any clue about this..
according to my thinking.. i think some button is pressed continuesly.. but everything is working fine.. only the touch is not working.
broken digitizer for the touch screen, buy a replacement lcd/digitizer together and replace yourself, about $100Aud. Use Mike Channons site to download the service manual. Use the search function and type in "htc service manual hermes".
As for the light, you will have to use your buttons to navigate to settings>system>backlight>battery power and external power. you can select how long the backlight remains on for.
Cheers...
Hi mate thanks for your reply.. Actually the situation is that. the screen is working perfectly. all buttons are also working perfectly. but suddenly the touch feature stopped working.
that time i was just opening some menus and they closed automatically. it looks like that there is some button pressed. and the screen light never stops. it continuously remains on. all buttons are working perfectly and everything. on the touch feature is not working.
i upgraded my device with genuine shipped t-mobile wm6 rom and again it stopped at the starting screen where i have to click the screen and the device brings the window for stylus adjustment.
so i wanna ask that is this also possible that some touch drivers are corrupted or something like this.? or is this a hardware failure.?
Kind Regards
I had same problem, it was hardware. Thats why I said to change the lcd. It is theoretically possible to replace JUST the digitizer, BUT, it is a MAJOR hassle.
As for getting past the alignment stage, look up Remote Screen Alignment. Its a cab file that stores the alignment settings on your pc. You WILL have to have a friend that has the same phone so you can get their settings as you need to copy them to your pc first. You can then copy the settings to your phone so you can use it until you replace that pesky lcd...
Cheers.....
I had a similar problem with my hermes. After a lot of investigating, I found out that this is a heat related issue with the hermes. The unit will heat up an some connection somwhere gets messed up and continually registers ghost taps on the upper right corner of the screen, which causes the continual opening and closing of programs/task manager. This overloads the phone which then causes the screen to eventually become unresponsive due to excessive computing.
With my phone, it must be heat related because it will only occur during or after heavy use or overcharging. Other people have had this exact problem with the conclusion being overheating. The worse part is, there is apparently no way to fix this, replacing the screen doesn't change anything. setting your screen alignment very far left will fix the problem but then everything you tap needs to be compensated for.
Good luck, hate to be the harbinger of bad news, but it's better to know whats wrong and that you can't fix it then not know whats wrong and keep trying to fix it.
same problem here... only my hermes is overheating already after 5 minutes use...
in the morning it works and when i put it in front of the airconditioning the touchscreen also works...
somebody who has an idea where to look for a solution??

Some of the suggestions in the white screen thread/s might help. The problem is that those who have the heat related problem will find it very difficult to trace the actual fault. The heat may be causing miniscule expansions on the boards / components and connectors. The tiniest of cracks or poor connections can therefore break with the expansion.
Another theory is that rather than heat it might be a capacitor that is breaking down either over time or again through heating. Unless you are a skilled electronic engineer that is virtually impossible to check, particularly since schematics are not available.
You might just be lucky if you dismantled and re-assembled - it might just re-set a connector or adjust a board so it does not get affected in future. That would be very much a matter of luck and of course potentially the situation might be made worse!

Hi mates. I am back with some issue.. i moved my device to a repair center and he said that its a software issue. and he fixed my device without changing any rom.. i dont know how..
but again when i open some window like programs. the right scrollbar make a problem... when i move scrollbar it automatically press the top close button..i aligned my screen 3 times but same problem with right side scroll bar.
and after playing with it. the touch totally stopped.
now the thing is.all the buttons are working fine and everything is working fine. even sms and calls. but when i check sms and press my scroller button. it displays the right click menu instead of opening the sms. and the screen light is continuesly on. as something is pressed. so. i think this thing wil help. i am now trying this method to check my pc.

check this out as well.
i will send you details soon.
might just have something lodged between the case and screen.. also to get rid of the screen alignment, cable it up and delete welcome from the startup programs and then reset it.. should get you past it so at least you can use it until you repair your screen
Hello, My G1 has just suffered a problem, i was scrolling down a web page and the screen faded out like it had lost power but the backlight was still on, the keys lit up and it still could make the trackball clicking noise when you moved it. I took out the battery and left it for 5 minutes and rebooted my phone and the screen turned on for about 3 seconds and faded out like before but it did boot into android as I heard the notification/startup sound. I think that the screen has burnt out but im not shore so has anybody had this problem before and/or might know how to fix it
Just some more infomation, If the screen dies and I leave it for a few minutes, when I unlock it or slide the screen up, the screen works for a few seconds but then fades. Also the fading looks like the screen lost power or like its losing pixels
From my experience with phone hardware this doesnt look like screen problem, but rather the lamp driver in the motherboard. the only way to narrow down is test the motherboard /screen with another phone.
If this is the case, it might require servicing the backlight driving circuit, which by far requries soldering/desoldering some components in motherboard.

had the same problem its a hardware issue. tmobile sent me a new phone no questions asked
Thanks for the replies, it seems that it has fixed its self as I've been using it for about 5 hours and no problems so far, I'm using it right now to type this, if the problem persists I will try and fix it or just buy a new one
So my phone's screen suddenly stops responding to touch, flickers and the display gradually dims to a few horizontal lines.
It spontaneously starts working again, but is still dim and streaked. All the phone buttons are perfectly working however.
I've hard reset the phone, removed the battery and sim and restarted it again but neither made a difference.
This is a German phone, so Samsung US support cannot help in any way. And no, I can't call them in Germany.
You don't have to offer a magic solution, but if you at least know what the cause of the problem is I'll be extremely grateful.
it happened to me just once & gone when i was on marketplace
i don't know why , it just gone .
I have a really annoying bug in my WP7 HD2. When i make a call, the screen goes black and i cannot access anything. The call connects fine but the whole phone locks up. I can't access the dial pad for using automated services, nor can i hang up. Hardware buttons do not work either, but light up briefly if i push one. I think its something to do with the light sensor, sometimes if i cover it and uncover, the screen quickly comes on then goes off again. Any ideas? I am using the latest radio from the stock HTC WM 6.5 ROM, and the newer (51t?) radio for WP7. I have tried older versions of both, and a few different WP7 roms all with the same problems.
WP7 Mango (xboxmod/yuki)
UK HTC HD2
This problem also happens on android.
Uhh, sounds awful 'cause you experience also on different Android...
Do you experience this also on a Stock WM 6.5 Rom (of course with the original radio and without hpsl)? If not, you can be relaxed cause it's no hardware fault then. If it's also present on WM 6.5, then it's very likely to be an hardware error.
a little update on my problem. it appears that if i tilt the phone at a 30 degree angle downwards, while in a call, the light sensor functions normally. so at least navigating those phone menues can be done! i think this is a hardware problem, my HD2 did suffer a pretty nasty fall (which resulted in a new screen!) so maybe there was some other damage beside the screen.

there are two sensors together to the left of the earphone at the top of the screen, one is a light sensor, the other a proximity sensor. It seems to be the proximity sensor that is at fault. When you put your ear to phone it switches screen off so you dont push buttons.
I have read that the prox sensor can become misaligned when replacing screen. Did it occur after this? warranty?
as soon as i make a call the screen switches off. also the auto brightness doesnt seem to be very responsive. the issue had happened before but it was more of a driver issue than a hardware fault. i noticed it more after the repair, but it was not instant. maybe one of the sensors was lose and after a few months of use it is now misaligned? the phone is out of warrenty, and the 3 month warrenty on the repair is also up, and i have no insurance anymore i am holding out for a new phone. just started a new job so hopefully i can get something outright without being tied to a contract
Same problem
I'm having the same problem I think I noticed it when it was running windows 6.5 but I really noticed it after 7 upgrade. as soon as I make a call I cant access anything. THe bad thing about it is this phone is a replacement. I just got it. Maybe they sent me a badly refurbished one. Has anyone found a solution to this. If i'm smart I know this is not as simple as changing a setting sound like re flash, erasing, re installing, etc.
did you try tilting the phone downwards towards you? when i do this the menu appears and i can access everything. normally i put it on speaker then the screen stays lit then i cna use it as normal
I have a Moto G4 that has had the touch screen become very erratic lately. This issue appeared shortly after a factory reset. The phone is stock, recently OTA updated to NPJ25.93-14.7. It frequently freezes and won't respond to touches of apps or the home/back/recent buttons, and won't side scroll to the next screens properly. Sometimes random apps launch on their own without any touch, and if you try to quit them with the back button they keep relaunching. The problem is intermittent.
I activated "Show Taps" in Developer Options and when the problem is happening there is a tap dot near the lower right side of the screen. It bounces up and down a little bit and vibrates sometimes. When this dot is visible tapping on anything else like app icons or buttons usually has no effect, however the taps are shown on the screen. If I hit the power button to make the screen go black it will sometimes recover when I reopen the display, other times it takes a reboot.
Wondering if it's a hardware issue, a guy at a Verizon store who seemed to know more than most said it was a faulty digitzer--it's seeing touches where there are none. I've replaced displays successfully before, would just like to have a confidence level that the digitzer is really bad before doing that, as opposed to a software or other hardware issue. Any ideas about problems that might cause this problem, like other hardware or a corrupted OTA? Seems very hardware-ish to me, but I'm no expert.
I have Drive links to a couple of short videos on the symptoms, can send links. Much appreciate any insights.
Mine has that issue as well. It will spam the 9 key on the unlock screen or anything in that spot if an app is open or what is on that spot at the home screen. I have to double unlock the phone to fix it. I guess turning the screen on and back off resets it for that session. But it's mostly every time the screen goes dark and comes back up I have to turn the screen off and back on to use the phone.
I had a similar problem and was able to send it in under warranty and get a replacement phone
G4 Digitizer or ghost touch
Apparently this is called Ghost Touch issue, and affects many phones. One solution tried is to disable Battery Optimization for System UI and Google Now Launcher in Settings>Battery>Battery Optimization. That seemed to cure it for a week or so, but the problem returned today. I can sometimes recover form it by hitting the power button to blank the screen and then reopen. Other times it requires a reboot. I see all kinds of alleged solutions out there from dimming the brightness to removing tempered glass protector to using a slow charger, but those don't seem like real fixes but workarounds (if they even work at all). Any other ideas?
