have just noticed that there is pixel stuck on red on my Orbit, only one I know, is there any thing I can do?
TFTs are getting better, but dead pixels still happen. When they die there is nothing that can be done except change the screen.
Not sure if the same applies to touch screens but it has been possible to un-stick lazy pixels etc... Two methods I can remember are having the screen flash diferent colours rapidly (there was a prog that did this for pc's), and the other was to gently massage the affected area of the screen.... Have heard of both methods working for pc flat screen monitors. Worth a try

Just received my second One X from amazon UK (first was sent back due to charging issues).
Been getting some weird things with the screen on this one, which I haven't heard of in the other threads. I have a fair amount of pixels on the screen that will flicker white on certain screens, particularly on the pull-down notification. The pixels seem to be roughly distributed along two vertical lines on the screen, and there's about 20-30, although it's hard to tell since they never flicker all at once. The white pixels don't show up in screenshots, so I don't think it's a software issue, although it's possible, I suppose.
They never show up on solid colors as far as i can make out, but i get them on the camera preview and in the notification drawer (seems to be that shade of grey combined with the fine texture that sets it off). Very occasionally I get it on the bubbles live wallpaper. I also get it when viewing screenshots of the notification pulldown, so it seems to be the colour/texture, not the actual window being drawn.
I can't tell if this is a software or hardware issue.. I've done a few reboots and a factory reset, which did absolutely nothing. It's always the same pixels, which suggests hardware to me, but then it's oddly specific circumstances that set it off.
Any ideas/anyone else getting similar issues?
Edit: re-reading your post it may not be what I thought. Info below for the "usual" screen flicker issue.
It's a well known issue that pretty much everyone has. The backlight flickers slightly due to a voltage drain when the CPU is busy, causing whites and greys to turn a slightly warmer "colour" for a moment.
It's fixed in the 1.29.11 (not 1.29.7) update which just rolled out in Europe and should follow in the UK in about 2 weeks. It takes up to 2 more weeks after the update for it to monitor the voltage of your individual screen and learn to compensate so the flicker goes away.
Yeah, it's not the backlight, it's literally single pixels flickering from their correct colour to white.
So I've been through the standard factory reset crap with customer service, and they're recommending I sent it in for repair. Has anyone had any luck with the repair centre (I'm in the UK)?
Not sure if it's even worth sending it back since I'm still not sure if it's a hardware or software issue. If it's a software issue, will they fix it, or will they just turn it back and go "nope, couldn't find anything"?
I have EXACTLY the same issue, but with two pixels only, I'm almost convinced it's a hardware fault because I'm on a custom rom and it's still there, I got mine without a warranty though so I'll have to deal with it, any suggestions other than acceptance?
I have same issue, i change the rom and now its fine. it was almost on 3 or 4 roms, and finally its disappear

Well thank you that's rather comforting to know, fingers crossed
My little sister bought my old htc desire, it has always functionned perfectly. It has the screen replaced 10 months ago with a cheaper non-htc/original screen. It appeared more brownish but as functionned perfectly ever since (and seems like it has some self-repearing capabilities).
Now 2 days ago my sister let mee see the phone and the screen was totally white. (Actually with some vertical lines visible with a wood-like texture). With the screenshot/monitor tool in the SDK it appears that in the background the screen is rendering normally.
Today I tried to boot the phone and some werid atefacts showwed up. Some parts are now readable and when you look closely you can see the structures on the screen.
Can someone tell me what this is and what is the cause of it?
It looks not good. In my opinion its non iryginal screen is dead.
--------------------------------
P.S. might be half detached wire connecting the screen with the board, or a broken screen...
Ja sam mali Fran i fappam cijeli dan!®
can anyone help me get rid of these spots. i dont know how they appeared. 3 days ago my mobile was switched off. when i switched it on i found these spot. they r green,yellow and black in colour. whenever i switch off my mobile for like 7-8 hours these spot becomes lighter in colour but after using for sometimes the colours get darker? can someone tell me are these dead pixel or stuck pixel?? and is there any way to remove them??
It is something happen wi th you screen and it happen when some hard wad put on screen. You need to change your screen,but any cheap from amazon.
Sent, from my HTC Desire HD
Thanks for the reply. So do i have to change the lcd only? Or the digitizer as well? Bcz touch screen is working as it should.

Before changing the screen you can try with some applications.
On the play store there are some applications meant to resolve this kind of issues, altought thery're useful when the pixel are struck on one color (red, green or blue): search for applications like pixel fixer and such.
A similar problem occoured to me (on a different device) and I improved the situation with this kind of app, but in the end I had to send back the device to HTC (my stain was four time bigger compared to your) which repaired the screen for free (the device was still under warranty)
Hi, maybe someone have encouter similar issue and have and could comfirm if there could be anything else i could do except replacing whole lcd+touch, which cost pretty much same as new unit
My my screen is showing some weird artefacts on screen, at first there is not much but its getting worse after few muniutes of use. If i lock and unlock the device i show white light bleed on left side of the screen (first picture) then if i lock again, wait for a while it disappears, but some artefacts and color pixel start to show on left side (second pic). After a while some strong white lines apear, always in the some spot, but if i put down the device for few minutes it desappers. Reattaching battery didn't help, i guess thats not the case. Could this be a faulty LCD connector? Or the screen is dying.. ? Definitly not a software bug, i just upgraded to 6.0 and even in bootloader mode while upgrading there were those two lines (last pic)
What screen brightNess do you use. It's recommended to use 20% to avoid screen burn in

Hmm.. since i usually use the tablet in bright locations its probably set to higher then 50%, at least..
There is one more thing, after like 10 minutes of use, almost all the above issues stops, only thing that stays is the "burned like" vertical stripes, barely visible, on about 2/3 of the screen.
I does not make the table unusable but its quite annoying...
could this be affect of screen burn in ?
i think its just a bad screen from a begining cuz i have tab s 8.4 for almost 2 years now and i gave it to my brother for a year and he was in Tenerife...temperatures there are high so i doubt its a screen burn since my tablet is still ok even after one year at Tenerife with probably brightnes always on 100%...just sharing my xperiance cheers guys
Wondering if anyone has any advice on something, plus I'd like to make some observations on a common problem. I dropped my phone about 4 months ago from about 3 feet up, in the cold (around 5C). Since then, I've had vertical lines appearing on my screen as in this post (https://www.asus.com/zentalk/thread-70061-1-1.html). Only difference is the lines don't extend all the way up the screen. There is about an inch at the top where the screen is normal. I have a few observations about the issue:
- It does not appear to be a broken screen. I replaced the screen/digitizer/frame assembly with another (used one), and it worked at first, but developed the same symptoms after a few days, out of the blue (did not drop).
- I can coax the screen to act fairly normally if I display a mostly white screen (either by inverting colors, or by setting a white background/opening a white app, etc)
- After a certain amount of time with a "mostly white" screen, I can revert to a dark screen and it seems to act normally and display dark colors again/can see everything on screen (not always though).
- When it's funky, I can see a vertical line about an inch from the top that flickers - above it, the screen is normal, below the screen is funky (vertical lines)
- It happens randomly, as in it will work normally, I will shut off the screen, and when I turn it back on, it's funky again.
- Weather/heat/cold appears to have no impact on it.
- This occurs during boot and in TWRP recovery, so it's not caused by software (doesn't seem like it's ROM dependent, by the way, I'm on CM 13.0), perhaps by bootloader which is common for everything that runs on the phone?
From these observations, it seems like it's not the screen that's the issue but rather the board the screen connects to (inside the phone, top board with the camera/volume attached to it). Does this seem right? I can't figure out why the screen would work when mostly white is displayed. I had a theory earlier that perhaps a (nano/micrometer sized) crack developed on the transparent conductor used to build the TFTs that drive the individual pixels - that would seem to make sense of the "white". As the lower pixels are driven, sufficient voltage/current is supplied to bridge the very small crack that occurred, leading to a (mostly) normally working screen. However that would have been fixed by replacing the screen, so it doesn't seem like that's the case.
I see two possibilities:
- The board that connects to the display has something that cracked/shorted like I mentioned above and sufficient voltage/current bridges the crack
- OR The second LCD is also broken - however this doesn't seem to be the case as the screen worked perfectly for a couple days. I haven't had the screen work for that long since this happened.
So, what are everyone's thoughts? I'm out of warranty. I could try replacing the board or just get a new phone. Or perhaps someone else has some insight...
