Screen issue-"Burnt in" image on gray backround

Hello people,
I rarely see a burnt in (like old crt screens) image on the bottom of the screen.
For example when I change the volume, the softkey labels of the today screen are still visible, along with a white line. Most times it is normal so I don't worry very much but I'm wondering if someone else has the same issue.
I've tried many versions of hardspl (because they seem to be connected with some screen issues) but the problem still exists.

Hi i have the exact same issue, i put a post up a month ago not had any response on it. I have a MDA compact IV, not updated any ROM or HARDSPL yet. I was tempted to update to see if the problem could be rectified.
Have you update to a cooked rom? I might send mine back to have it fixed if its a screen issue.
Mine only holds the "burnt in image" along the right of the screen from top right corner to bottom right corner around 3cm in.
Also i have noticed the "Burnt in image" seems to get stronger when the device heats up. If i use GPS or 3G, this seems to affect the screen.
My background is black which makes it really noticable, i think if i stick with the orginal t-mobile white background it's probably not that noticable.

mmm
Perhaps the units you bought where like demo units. Those units that are displayed all day long turned for people to look at them. I have read in another forum that perhaps that distortion is caused by extreme temperatures, cold or heat.

well i'm still trying to figure out what is causing it, as I notice it only once in maybe a week. Maybe temperature is the most probable cause. For me I notice the defect only in gray background (e.g. when changing volume or launching opera).
My unit was from the first batch from expansys (origin htc asia)

It's possible your handsets have screens which are somehow susceptible to heat damage from inside the phone. This would be no fault of your own, but a manufacturing defect.
I'd suggest returning the phone to the retailer, HTC or the operator depending on your situation.
However, if you're using the phone in extreme conditions, ie low temperatures, you may very well find the LCD slow to refresh or have some level of image retention.
Let us know the outcome

i also have a ripple effect when pressing, but its more apparent with black. its also a first gen model, so i think ima make a phone call to htc. maybe a can get a new device.

for the burn in, try this:
1. Go to power settings, deselect automatic backlight management.
2. Pull up backlight level to maximum.
3. Reselect automatic.
You should be ok!
If not, faulty device!

Ok I will try this although I can't see how the backlight can affect the screen. In order to repair it with warranty I would have to send it to expansys uk (because it is not a European device) and I bet it would take long

Have you tried removing the battery for a while - some lcd screens can get the memory effect, and cutting power for long enough normally cures it.

My phone actually holds the previous menu under the current menu.
Example i'm on the home screen, goto messages and send a text using the qwerty keyboard. Back to the home screen, i can see a very faint image of the qwerty keyboard under the Programs hotkey.
When the PIN lock comes on the bottom right is "MENU", i can see a faint "programs" letters icon underneath it.
I will try and leave the battery out for a few hours, if not a call to t-mobile!

ok, i have the same "problem". even after a soft-reset the words CommManager
and Programs are still slightly visible in the boot screen.
but: as mentioned above, turning the device off for a couple of minutes cures
this, and the screen is dark as hell again!
really seems to be some kind of memory effect!
regards,
markus

Left the battery out for a few hours, made no difference. I guess is not a software problem.
will be giving t-mobile a call tomorrow!

:-(
I guess every htc device must have a flaw...
when it does it again I will try to take a photo of it and post it here

Hi same problem here.... See my post below..
http://forum.xda-developers.com/showthread.php?t=417629
I thought it was due to Spb Shell but no, now i'm happy i'm not alone..
But what solution for this??
I'm not worried about the burn in looks.. My worry is whether this behavior of the screen will progressively damge the screen???
I have been using the Diamond at full backlight.. Last few days i've put it down to minimum, but the problem persists!!!

ok, I think it happens when it overheats.
So that is why it is caused when charging.
wtf?

No its not due to overheating, coz LCD screen are supposed to tolerate temperatures upto 80degree C... Dont know if its related to electro magnetic radiation, may be looks like it's more after i use the network...

Hi another mate has this problem Andrew...

Hi,
i sent my phone back to T-Mobile hoping they will fix this issue with the screen. Just received the phone and it looks like they have done nothing On the job sheet all it says is "Software updated"? The problem is still there!
I dont think there is a fix as such, it looks like this is the cause
http://www.practical-home-theater-guide.com/image-sticking.html
I'll try if i can get a completely white background and leave the screen on for a while at the brighest setting, if this will erase the screen issue?

the problem appears more often now on my device....
It does not have to do with heat afterall.
Why would the image "stick" when the phone is off? I mean that many times I see the symptoms right after I switch the phone on.
Do we have any screen experts in the forum?

After calling up T-Mobile and made a complaint saying nothing had been done by the repair centre, they gave up and agreed to give me a handset replacement. Received the handset today, looks like a refurbed one? Anyway my problem is now fixed. Left the phone on a while and it got pretty hot, no ghosting on the screen
The restore was a pain, Wifi didn;t work, the HSDPA didn;t work. But after a few hours messing around it's all up and running so far.

[PROBLEM] Died?

Hey guys, I was wondering if somebody would be able to maybe help me diagnose the fault\problem part with my non-working diamond...
Basically I went to a club one night and the place was unbelievably steamy / humid. My phone was working one minute and then the next it wouldnt display anything on the LCD. The backlight was working however.
Since then I havent been able to get an image on the screen although when trying to turn it on, it seems to go through its startup sequence (backlight -> vibration -> beep (i think))
I havent had any power to the phone since a day after it broke (a few weeks ago).
I'd like to get it back working again but dont know exactly what part i would need to replace. I'm fairly competent with electronics .
Any help/advite would be appreciated!

Haha, ok that's odd...
I've plugged it into my pc to get some data files off about an hour ago.. forgot about it and just looked at it now and the screen is displaying!
It is displaying and accepting input although it was flickering at first (like pixel shifting). but i pressed the power button to standby the screen and pressed it again and the display is fine with no flickering ?
Ive moved the phone about and shook it quite hard to see if there's any loose connection but the display still seems fine..
Anybody have any ideas as to what it may be?
I'm not going to deem it as fixed until I know what the problem was/is lol
cheers guys

Ok screen actually keeps flickering nonstop, and sometimes 'fades away' to gray/white/black
comes back after a few seconds though

Looks like a faulty connector?

[Q] Phone works, screen does not yet sometimes it does

Hello
One night I was using the phone without doing anything special , some video watching . Phone went dark, tried to reboot. Blank Screen and the capacitive buttons flash. Left it to charge all night, in the morning it started but after I pressed the lock button blank screen but phone still working and receiving input.
Took the battery and SD card out left it for 30 seconds then started it again, Stuck at LG logo. Repeat , phone started ... Pressed lock button once then again to unlock , screen wouldn't start.
Used LG Mobile Update recovery tool to restore it ... Didn't solve problem. Sometimes it does not even start , just flashes buttons, other times it does without screen and last all works even the screen until first time goes dark , in the last two cases I can use LG On-Screen Phone without trouble, in doing so I installed a proximity sensor test app to see if it was causing my screen to not come back on , the sensor looked fine.
Facts:
1. Two day old Optimus Black p970, worked like a charm until stated problem
2. The app that checked proximity sensor showed the sensor to be free when my hand wasn't on it
3. The warranty laws in my country are idiotic so I would do or buy anything rather than send it so they can give me a new one in 3 months.
4. Tried another battery from another Optimus, fully charged nothing different.
5. Stock rom.
Do any of you fine people have some ideas on how to fix this? Thanks in advance

Hi there...
Sometime ago [1 year and a half or so~] I worked at a cell refurbishing facility [there were samsung, motorola and palm devices from sprint] and that problem you have was quite usual. Blank screen, still the phone is somehow usable like reciving calls...
There's this thing called "flex" which is the connector between board and display and that is what we fix, most of the time not even "fix it" just getting it in the right place...
This happen because of excesive use in those sliding or clamshell devices, in OB could be for overheating, you could try to fix it yourself or pay $20 usd [that's what it cost here]

Would that connector explain the fact that sometimes it doesn't start at all? hmm I am thinking now and I guess if it moves and somehow the phone feels it has not display connected it could fail to start... Anyhow thank you

actually yes, it could be only for the flex [some devices don't start at all when not having display or keyboard if there's any] but since our OB is not sliding nor clamshell type probably was overheating.
you say you have stock rom, well now I'm using CM7 but when I was at stock and after using the phone a few minutes it felt warm and some more minutes [like playing gunbros where you need to use both hands and a lot of movement] it was really hot and had to stop playing for a while.
what I'm trying to say is that because of overheating flex could have moved, but because of overheating too may have move something else, you couldn't belive the huge number of micro-things that reside in the board.
so if it's only the flex, it's an easy task to do, just unplug and plug again, but if it's something else it's quite hard to know just looking at it, you need to do some electric measures and stuff, the recomendation is to take it to a tech center or something

Hi. I Have same issue. Two times when i press power buton, butons flashing and screen still black. Phone not responding. I must remove baterry.

Hi there, got the same problem too with my optimus black. Screen goes flickering, shut down don't do any good, and the phone temperature is kinda hot. But in my case it work after I clean some cache and data in the phone storage through LG OSP. After that, the phone temperature back to normal and the phone screen back to normal also. I believe that in my case the phone is overheated.

[Q] Galaxy S I9000 Problem turning on...

Here's what is going on...
My Galaxy S I9000 (Bell Canada) was water damaged, after being dried for many days it turned on, but the battery almost immediately drained. I left the phone and forgot about it. Bought a new cheap phone without a SIM.
More recently I got a new battery for it and it turned on and was working great, staying charged and everything. When I went to the service provider to get a new SIM for it, we powered down the phone, pulled the battery and SIM card and put the new SIM in followed by the battery. Afterwards the phone would not power on, but the two face buttons on either side of the 'Home' button lit up and would react to touch. I tried removing the battery and SIM a few times and would get the same result.
After bringing my phone home and leaving it with the battery out for a few days, I thought I would try it again. It powered up again as if nothing was wrong. To test it again, I pulled the battery and SIM, replaced them, and my black screen/won't turn on problem returned.
Every so often it will power on and be useable. It is recognized by Kies, I've flashed it to firmware 2.3.4.
I'm looking for any helpful suggestions for what might solve my problem. I'm wondering if it's a hardware problem and short of isolating the part of the phone that is faulty and replacing it, the phone is toast.
Thanks for your time, and I apologize for the length of my post.

My friend has dropped the SGS into a pool before. Problem was fix after buying a new battery.
Either: Damaged screen + Contact. Or the reaction with water and the battery. hydrogen gas prevents screen from connecting to main-board.

It still turns on occasionally, and when it powers up, it's as if nothing is wrong. Screen works, displays everything fine, colour is crisp, screen reacts to touch. The big problem is it won't turn on all the time. Would what you said still explain this?

The only thing I know (assuming the screen or motherboard is 100% functioning) is hydrogen gas being present. You might know TV remote with old battery casually respond to presses. After cleaning contacts it should work again.

I disassembled the phone and cleaned all the contacts on the main board with rubbing alcohol, I did not do anything to the screen though. Should I try taking it apart again and breaking it down further? (ie. separate the screen?)

No, I am starting to think it's a hardware fault if that didn't work

Is my phone broken?

Hi Fellow Citicens
My screen turns off occuationally. The screen just fade off during couple of seconds. Especially if I have navigation turned on, screen will fade away less than after15 minutes.
I need to shut phone off and make it little cooler if I want to get screen back.
So what do you think. Could it be sw problem or is my screen/sensor just broken and I need to get phone fixed by professional service?
Thanks for your support,

Take it to service for repair. Just to be sure everything is covered. But i think it is H/W problem. Not sure, but i can only guess.....
