sooo, yeah. my wife has the t959v. the screen cracked months ago, replaced it with one from ebay, works fine. a few weeks ago, it was involved in an accident and needed yet another screen replacement; ergo, back to ebay i go. installed the new screen yesterday, turn it on, all is well. for a bit.
now, the phone isn't currently, nor has it ever been rooted; pure stock tmo us 2.3.6. during boot, the splash screens and boot animation are gorgeous and perfect in appearance. the recovery menu is exactly as expected. android boots as you'd want it to, and then the display will do one of the following:
-work properly (rare)
-automatically turn off, capacitive buttons still lit, touchscreen unresponsive - turning it "off" darkens the cap buttons, turning it back on flashes the screen on for a half-second, then off, with cap buttons still lit (common)
-graphical corruption ("solarized" colors, completely wrong colors, pixel vomit in essence) (fairly common)
-screen tinting, blue most often, followed by pale yellow, then greenish, then red (almost constant)
-screen inversion - the display will show as rotated 180 degrees; grabbing a framecap in ddms shows it right way up. touches are also inverse; you have to touch where the onscreen element would be if it were displayed properly instead of where the element is; e.g. a button on lower-left will display in the upper right, upsidedown, but the screen registers the button when you touch the lower-left portion of the screen. (quasi common, equally infuriating and hilarious)
none of these problems will show up in a screenshot at all.
i can reliably reproduce any of the above by simply adjusting the screen brightness. this will, quite literally, cycle through every possible defective display mode randomly for a split-second before moving on to a different one as long as you move the brightness slider.
MOST of these issues are transient and are either fixed (temporarily) or replaced with a different listed issue if you lock/unlock the display. it feels like a hardware issue what with the solarizing and color horrors, but is acting like a software issue, considering that recovery and boot are perfect and have never displayed any of these issues. i tried gently flexing and stressing the case in areas that might be a weak connection point, but can't get it to bug out that way.
in no way am i suggesting that i didn't screw something royally in the reconstruction stage, but i tore down and rebuilt that phone 4 times with identical results, so i can guarantee it's not some loose ribbon connector or zif socket.
i beg of you, great minds of xda, what the balls did i muck up this time? any hope for a fix? are there different panels, drivers, something?
thanks in advance
OK, if your screenshots appear normal, then your phone appears to be working correctly!
or at least it thinks it is we can conclude that it isn't the rom, kernel, or anything that you can blame the phone for going screwy.
Try buying another screen??
The ribbon connector might be broken?
yeah, these were what i figured what my options were. it just seems odd that the boot process and recovery menus have error-free displays while only the full android os doesnt. oh well, i'll probably just have to make a stink about it on ebay or something.
thanks for reading
You might try a fresh flash before getting a new screen to see if it is indeed a hardware issue. If you want to try that follow the second link in my signature. You will not need to flash bootloaders since you are currently on KJ6.

hell, warranty's void at this point anyway, right? may as well thanks much!
welp, all went well, screen was perfect through the whole heimdall/recovery process, but the problems still exist in the os c'est la vie. at least my wife's phone is finally rooted, i suppose. thanks anyway!
Have you tried opening it back up and reconnecting?
yup, 4 times, but i guess one more wont hurt
[edit]
it definitely seems to be related (if not related, exacerbated by) changes to screen brightness. turning off autobrightness has helped minimize the issue, but it still presents itself semi-often during screen-off/on events. obviously nothing useful in logcat.

That's interesting and could very well be a hardware problem with the screen. You wouldn't see that in recovery as the OS isn't loaded to mess with the brightness in that mode.
Does it do it on-demand if you mess with the brightness slider?

you better believe it does. rapid fire cycles through every color until it can't take it anymore and turns off. if i take/refresh a screenshot through ddms and poke blindly at the screen at that point, it'll still take input which is a curious, difficult game to say the least.

It's that Pink Floyd screen. You're supposed to drop acid & watch the wall when that's going on. LOL j/j
Given that you're on a fresh ROM & the problem persists, I'm leaning toward a hardware issue man. Sorry.

as fun as that sounds, unfortunately i bet i'll end up just getting my wife a used phone on ebay or somewhere similar and using this one as a development monkey. i was assuming that it wasn't something i could fix but hoping otherwise... yeah, that worked out
I just started having this problem. It wasn't too bad at first, just the color changes, but then it started not showing a screen at all. Changed to three different roms, even back to the stock non-rooted KJ6 and gave up. Keeping it on a steady brightness is the only way to minimize the color changing. I thought your thread had a solution but...
I may try opening it up and fixing the ribbon. But otherwise I'll keep using it as long as I can tolerate it until an S3 or a new Nexus.

nawp, nothing even close to a solution here i did end up buying my wife a whole new replacement phone and turned the broken one into my api10 development device. for what it's worth, yeah, autobrightness off does help a bit for when the phone is actively displaying content, but after you put it to sleep/screen off and try to turn it back on, it's a crapshoot. for a few horrifying hours, the screen was upsidedown even in recovery/boot animation and would NOT flip back to right-side-up until i ran the battery completely flat.
is no fun, 'tis truth. sorry for your troubles.
Hey guys, i'll try to explain the situation as best i can below, hopefully someone can work out what is wrong.
My phone is about 16 months old. About 2 months ago i dropped it twice within the space of a couple weeks. There were a few cracks along the screen, however it wasn't very noticeable and i wasn't going to bother having it fixed. The problem started a couple of weeks ago when i went to grab it out of my pocket, however i found out the screen was black and it wouldn't turn on. I don't really know how to describe it but it was acting very strange...
- The screen would have white/gray bars all over it then turn off, then it would do the same with very thin vertical lines that were white/gray/other colours...
- When i get the screen on, it generally turns off again within 30 seconds, however it can stay on for a few minutes.
- If the screen is on and i press the lock button, it almost certainly won't come back on.
- Restarting the phone or holding the power and volume button nearly always gets the screen to come back on. It often then restarts but turns off again shortly after.
- The phone is otherwise still working when the screen goes off; the notification light stays on and i hear messages etc coming through
- The backlight often stays lit, revealing a gray screen opposed from total black. Sometimes it does not stay lit however.
- When the screen came on it was often unresponsive to touch
I had the screen replaced yesterday by a phone repair shop and the phone is still not right. I have factory reset the phone and also wiped the partition cache. Other than that it is still not working. IT seems to be working better... The screen always seems responsive to touch when it is on, and it doesn't seem to be turning off as often. It generally starts up and works fine when i start up by holding the power button and down volume button together... However even still it sometimes just flashes up with a few thick white/gray and black lines on the screen..
Does anyone know what can be causing this and how i can resolve it? If you need any more information please let me know and i will try provide it. I could try get some pictures of what the screen is doing when i finish work. Thanks guys, i appreciate any input.
EDIT: I managed to get a pic of what i mean by the thin vertical lines all over the screen. This just appeared when i tried to restart the phone after it the screen had once again stopped working. The imgur link is gIFMGD6
Anyone have any ideas?
Hey, did you ever figure this problem out? My phone just started doing the same thing. Can't find much info about it.

Yeah, i had the screen fixed hoping it would fix it, however that didn't work. Turns out it was the motherboard, don't know what was wrong with it in particular other than it was simply going faulty. Had someone replace the motherboard on it for $50 and have had zero problems since! Hope that helps you.
Thanks for the response. I tried replacing the screen too with no luck. Unfortunately the same place that replaced the screen said it would cost $400 to replace the motherboard!!! The phone cost less than that so it looks like I'm gonna buy a new one.

Hi,
I have this really weird stuff going on with my Nexus 5 screen. I cracked it a couple months ago and bought a legit replacement screen for it and installed it myself (glass, lcd and frame). I fixed it with good instructions and it worked properly for two months. However though, now when I take it out of a pocket and try to turn screen on, sometimes it just doesn't light up. It's still on and every button works but the screen doesn't turn on. I have to give it a light tap or two on the back in order to make it light up again. Same thing happens sometimes when I'm using the phone normally, the screen just goes black and goes on after tapping it couple of times. Otherwise the phone works normally like it did when I bought it two years ago and after running couple of tests with screen, everything seems to work from touch interface to the graphics card.
Tried looking it up, no results.
I've noticed that the front camera doesn't work for some reason (probably just broken) and the battery lasts in use only 2-4 hours which isn't that much of an issue since I'm looking for a new phone. I just want this one to last long enough till I buy a new one.
It comes up when tapping the screen or power button? It could be a power button issue.
The screen comes back on when tapping the screen or the back of the phone. The power button isn't the issue. The screen just goes black but nothing else happens. It doesn't turn off or go to sleep mode.
Strange issue. I've never experienced it and any problems I had were related to the power button.
Could it be a loose connection inside the phone? Maybe an issue related to the proximity sensor?
Thats actually what I've thought. I have checked the phone's insides twice and didn't see loose connections, and the problem feels like it's related to proximity sensor since the screen going black happens exactly same way that when calling someone or doing something else where proximity sensor shuts the screen. It's really weird though...
Huh, I took backplate off and unscrewed the motherboard cover and took everything apart and rebuilt it and now the problem is gone. Seems like there was just some bad connection somewhere.
Glad you got it to work without having to pay someone to fix it
I bought an Xperia XZs from a website called DWI Digital Cameras about a year ago (they've closed down recently due to the new GST regulations). I've had this issue since the day I received it and I thought it wasn't that big of a deal at the time, but it's gotten to a really bad point now.
The issue is that very often when I try to wake up the phone (like almost half the time) the screen does not display anything while the backlight turns on. The backlight might also flash multiple times as if it's trying to get the rest of the screen to wake up. This issue would usually go away for a bit if I either tried to open a camera app from the lockscreen (via double-pressing the power button) or rebooted the phone - the backlight would turn on and off a few times and the rest of the screen would temporarily work again. But now, it seems to be not working no matter what I try.
I'm pretty sure that there's nothing wrong with the screen itself, I even got it replaced once after I accidentally dropped and shattered it and the issue still did not go away. The issue also persists no matter what ROM I have installed as well.
Any experts on this? Cheers.
This is a mystery. BLU Energy Studio, phone worked just fine, then started to flicker and show funny colors then turn off, after few minutes/hours of REST, it would turn on for a few seconds, again, fully smeared colors, and shutoff. Attached is a video:
https://anonfile.com/Ice0Ifk1n5/VID_blu-lcd-flickers_mp4
Ordered an LCD + digitizer, and replaced BOTH as one unit, however, phone still behaves exactly the same as before..
What else could cause this behavior? This is lollipop/pretty latest revision, phone was very stable before this happened, I highly doubt it is the OS, it seems hardware related, but can't think of anything other than replacing of lcd+digitizer, which was done already crazy
Thanks for any tips.
