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.

screen problem, most of the time do not work

Hi, i think i have problem with my screen, it's not work anymore, so I decided to reflash device with official Rom. But it didn't work.
Moreover before windows system start for the first time ir requires to tap on screen to boot. So now I cannot use my TytnII at all.
Is it any options to boot it without tapping on screen?
Or just to flash with other ROM, but HARdspl is not installed so a bit afraid to brick my phone. please help

install hardspl (same procedure as flashing) and then install rom of your choise if it dosn't work have you done any of the following
dropped it in water
gone in the washing machine
etc.... stuff like that

why don't you get a new digitizer??? it's $10 for kaiser?? i've been changing them like underwear...every half a year.
what is it, what's asking you to click on screen? if it's just a welcome screen, put welcome.not file in root.

hehehe funny expression 'changing them like [email protected]
what do you only change your underwear 2 a year

hehe, i live in Lithuania, so price with shipping will be around 25$. I think this isn't very cheap. Finally got screen working, but after 30min of using again no respond to tapping, then again working fine, and after that again no. it's annoying. I think it's problem with digitizer? I haven't it dropped to water, it almost brand new

thats good you got it working
hope the problem doesn't happen again

if we assume the problem is harware, it would most likely by at one of two spots.
place, where the ribbon cable is soldered to lcd
or place where two piecies of digitiizer are connnected to each other.
might help if you check on the ribbon and glue a plastic tape all around the edge of digitizer, making it press little bit more on it
well, if that's hw probllem. but first you shoud try different rom. you can reflash without digitizer working. and check for pocket controller or similar if you want you can control pda from pc with it. there are two free and Pocket contr is trial.

if you just want to bypass the "tap here to use your device" message on the first boot up, search for "welcome.not".
create a blank file named "welcome.not" and place it in the root of your sd card and then power on the device for first boot up.
make sure it is a blank file. make sure it is named EXACTLY "welcome.not". if you are doing this with your windows pc, make sure you have turned off "hide file extensions of known file types". otherwise, the file might actually be named "welcome.not.txt" but might show as "welcome.not" on your pc.
search about it for more information.

hi, have tried differnt rom, but problem still persist. screen is not working, but sometimes it starts working very well. but most of the time it not respond. when backlight goes out and touch screen it starts to light but can't touch any options on. So what can be the problem, only digitezer or whole screen?

it was more probable it would be hw. but we need to eliminate all possibilities and reflash was easiest.
Still there is more things which could be the problem.
And there is no way to tell for sure what is it.
Did you say the pda is new? or digitizer?
And then you said when backlight goes off, digitizer will stop working, but still reacting on touch (to light the backlight) Is this right?
When will it stop / start working? Does it change if you press on body - case?
Does it change if you slide keyboard out or in?
There would be a short test each time pda/screen is powered, if digitizer fails in this test, it would be ignored till next test pass. Could this be your case?
digitizer could be broken on corner, or has bad contact inside
- You can test it, if you'll solder test wires on it and measure resistance, which should be around 500 ohms without touch and going down on each touch, can't go higher! test for both H & V
but the same reaction could be if ribbon cable connecting two parts of kaiser is broken (or connector on mobo side)
but if it's new it shouldn't.
and at last there could be problem on mobo. inside the controller chip or on it's connection, soldering. But not very probable.
It definitely looks like bad connection somewhere. You need to find out where, so you'll not buy digitizer if it's good or ribbon cable.
Put plastic tape around digitizer inside, as I wrote before, inspect ribbon cable and digitizer and it's connections. Try to locate event when it goes wrong.
If you'll not open it and check on these things, then maybe get a new part which will show bad, then I don't see how more we could help you.
You can use it without touch screen somehow or get a new phone.
Digitizer is US$8 with shipping to Lithuania. That's really cheap, even for us from central european countries.

and ribbon cable have fair price too,

papo very informative
All i want to add is that it's easier to replace the whole screen with a digitizer already on as the digitizer is very hard to remove since glued to the glass more than likely will get wrecked and not able to replace new, whereas full kit wont cost a lot more and will be less stress just 4 screws on the back plate of Tilt "where sim door is".

Well, it is not new, i've bought it from one girl, but it's like brand new, no scratching at all, very good condition.
also, yesterday i checked all the connection inside it, but the problem persisted.
I think I have understood what kind off problem it is...when remove sim card it stars to work perfectly. When insert sim, it work some time very well. Then again screen start not to respond, any ideas?

mm, I know some pretty good spells, but you need a magic wand to make them work. If you don't have any you need to:
tape the screen as I wrote before (half millimeter tape),
if no help, hardwire analog multimeter on digitizer and test it properly (while pda off and open) as I wrote before
tape bended paper across connector on mobo.
OR just get a new digitizer straight away. it's $8 and pretty good chance that it's the issue. it's maybe 50% chance but what I mean is:
You have $200 phone (now on market) let's assign it 200 points
It's working on 20% with digitizer broken, now you have 40 points
digitizer 8 points to add. With 50% chance to fix = 16 points to add
result: by adding 16 points you gain 160 (200 - 40) that's 10x gain = good risk

WTF with my screen? post photos. on the first my screen, on the second lcd screens which are beiing sold on ebay.
I decided to buy new digitizer, but when looked at my screen, it realized have completely different layout where digitizer is connecting to screen. Am i right? Is the digitizers which are sold on ebay will suit my screen?

that's fine. they all work. They are not oem but works well. Maybe not so scratch resistive.
You may get the digitizer solo, but they will not include a special double side tape which goes around and is holding it together. You can make that tape, but it's pain as stylez said. A lot of cleaning the used old one, then cutting small strips of ds-tape. and you need to put a paper or something in between two layers of tape as you need a little space in between. And then soldering that ribbon. Better just get whole assembly.
==
I see you tried that tape, before you buy it, try the last thing. The place where digitizer is soldered to lcd modul.
On that piece you sent photo of, you need to open back cover.
check the picture:
1. peel off antistatic tape from connector, from up -> down
2. take cover off
3. there will be attachment of digitizer behind the cover, like on your second picture.
Check for good connection
AND
check if soldered pins could not be touching the back cover you took off
( i had this problem once)
put electric tape accross it a give it a try - that will isolate it from back cover & make a little pressure if bad connection

MI3 New touch screen bleeding at the bottom

https://goo.gl/photos/R1ns1GnFzMq26kSXA
I broke my touch screen and replaced touch screen at the authorized service center "TVS Electronics at Ashok Nagar Chennai" India on 22-Sep-015.
When I went home the phone did not turn ON but was heating at the back side top portion.
I went back to the service center and they reset the phone stating there was dust in the charging port. (What it has to with the switching off. I don't know) The issue came up again after a week. This time the service center kept the phone for observation and retuned it. They said they did not find any issue.
But I observed there are 6 led lights visible at the bottom of the phone. This is visible more in the white background. (I have enclosed a photo of this taken from another mobile)
I was told by the service center all MI3 phone comes with this type of bleeding because it is a low end phone. I am one did not notice this in the old screen. In the service center I checked one Redmi phone and it did not have this bleeding. Redmi is cheaper than MI3.
I would like to know
whether this bleeding
1] is a normal phenomena of the phone?
2] an occurrence happens with some of the touch screen? [If so can I demand them to replace?]
3] the service center employee replaced the screen with local make instead of original MI3 screen to make money?
Kindly help me.

Hey,
No its not that.
I think they just didn't their job right.
Although I read it in the reviews of the device that
Unfortunately, the brightness of the screen is uneven with the backlight source being pretty visible at the top of the screen. When you have a white page opened on the screen you can easily notice the gradual brightness falloff from top to bottom

That is on gsmarena.
I think the display is original but they did a lousy job.

Contact Xiaomi somehow and escalate the problem, ask the SC personnel to replace it properly and that you won't accept it like that. Its most probably a job screwed up.

Try replacing the screen urself. Order parts from online shopping websites.

They definitely did not fix it right and every mi3 dont come with this problem.

Huawei p9 black screen

Sorry if this is the wrong place to post or it's been covered already. I have a p9 stock that I changed the screen on after dropping it. Everything was fine until the new screen started to fail, it was a cheap eBay screen and the glass started peeling away. I fitted a new one and when I switched it on the backlight comes on but no image, backlight then flashes 5 times and then stays on. The phone does the one vibration like it's starting up but after that does nothing. I tried the reset procedures but doesn't help. It wasn't on USB debug so I can't connect with my pc. I first thought the screen was faulty so had the vendor replace it but still have the same problem. Could it be the main board has been damaged or the flex cable?

Sounds like a batch of bad screens. I would stay away from eBay when it comes to Huawei P9 screens, too many issues with them. Had ones that were refurbished or glass separating from the screen frame.
Buying it without the frame and applying the adhesive yourself seems to work better for me. Anyway hopefully you didn't kill the backlight circuit on your phone.

Backlight seems to be fine. You could be right, there's a faint blue tinge in one area.

Hey, did you ever solve this? I have the very same problem

Screen Problem

Hey there guys,
Im having some problems with my Huawei P10 screen.On the left side of the screen on top there are some yellow half circles.One month ago there was only one and now there are three of them. Like on the top left of the screen.When the background is white you can see them clearly,when the background is black or any dark colour they almost disappear.
Do you think its a pixel problem or what? Like dead pixel or stuck pixel. If u know what it is can u help me to fix it?
Its not any big problem but its ugly to see them when u use phone.
Thanks

Are they present when you boot into Fastboot? Just test it, there's a white background. If yes, it's a hardware problem, maybe it's the display itself, or the flex cable or the display controller, or the display connector.
Go to a repair store, if you still have warranty send it to Huawei of, if you're able to do it by yourself, buy a display replacement (with frame).
