SAMSUNG J710F SCREEN GOES BLANK BUT PHONE STILL WORKS
I’m having trouble with my screen going off. The phone will boot up and just vibrate,pc&odine being detected , my screen is blank and the only way I can get it to turn on is to take the battery out and back in. This especially happens when I drop it (in water)(I have a case on it & it’s never been dropped hard).

its because your display is dead bro only way to solve the issue is to changing display

[Q] Screen is black but still reacts

The device is Samsung Vibrant.
So recently I replaced the screen and it has an annoying bright strip on its left side that randomly shows up from time to time, so I decided to reinstall the screen to fix it. After doing that the screen would stay black but it still reacts (it vibrates upon unlocking, etc)
Before I do anything else, I was wondering if anyone has encountered this and managed to make the screen work again, before I send it back. Thanks.
I think connection was failing and by replacing display it failed ...
yea probably. gonna send it back. thanks

Need help identifing reason for strange and frequent freezes

Hi guys
I have this strange behavior going on in my Sentation.
Out of nowhere my phone started to have strange screen behavior... Didn't light up after pressing the power button (had to phone my self in order to get screen on).
The next thing was that suddenly the screen goes to maximum brightness or goes to minimum without any explanation (tried both auto brightness or manual).
After that I noticed that the screen went off when I was using it but when I pressed the left side of it it lighted up and off again... making me think of some kind of bad contact underneath. As I already had changed a broken touch screen for t3 times, and let the phone fall for several times I thought it had to do with some plug out of line...
I disassembled the phone completely and mounted up back again. The thing is that the phone started to freeze every 5 minutes (screen on but completely freezed. I have to pul out battery). Sometimes it freezes even in the recovery menu. I've tried several rom's with full wipe and not installing anything and its all the same.
Some times I still not that the screen goes off during the freeze but when I touch the left side it goes on again, but that doesn't change the freezed state even that I let down the phone for several minutes.
I disassemble the phone again, tried different back cover and different battery (one stock and other extra strength) I tried also all the suggestion related to the small pin in the back not connecting well with the back cover (adding an aluminium foil, pulling the pin out, etc..)
Nothing seams to resolve anything so I have clearly an hardware problem... but I don't know what to replace or where to look the damage!!!
Can anybody help me please?!
Update
I have an update on my problem:
I noticed that when I leave the phone on top of some kind of metal part and don't touch it it works all day without any problem but, as soon as I start to touch the phone, it freezes within minutes!
Could it be some kind of static electrical problem? How to resolve it?
I would apreciate any help
Thanks

[Q] Nexus 5 display corrupts after boot

My Nexus has a display problem and i'm trying to troubleshoot what the issue is and I'm wondering if anyone could help as it's not obvious where the issue lies.
What happened is I was using it as normal this morning and then the screen started flickering to different sizes/colours until it finally just went off. It was almost like it is trying to find the correct refresh rate and the colours appeared polarised at one point. After holding power down to reset it, the google logo appeared and then the spinning dots. Once the boot was complete the android logo appeared and then as soon as the main screen was displayed the display cuts off with a white pixelated mist and shuts off. The phone is still running as if I connect via HDMI I can see everything as normal however the phone responds extremely slowly. I can get into recovery however the screen quickly does some strange things, it flips like a mirror and cuts 1/3 of the screen off.
I'm not sure if this is a LCD problem as its a replacement from ebay that I've been using for a few weeks now. I would suspect that before anything else however it's odd the pre boot logos display fine. I've checked and cleaned all connections however it's still doing it. I'm running stock 5.1.1 rooted.

Screen goes partly black

Hi all, I've got a weird problem. The last 3 days my screen has been acting strange. Phone is working without problems when suddenly the hardware buttons won't respond any more. After a few seconds the screen goes black and stays black. Buttons are still lit, but don't respond. But the strangest part is that the drawer stays visible and can also be used normally. I mean, I can draw the notification area down and let it fill the complete screen. So the screen itself doesn't appear to be broken.
Also, when putting the phone to sleep and awaking it again, I can see the normal screen a brief moment, maybe half a second before it goes black again. Restarting the phone is the only thing that will help...
I've cleared Dalvik/cache hoping it would make a difference, but it did not. Hope someone has got a clue?
I've uploaded 2 screen shots to show what I mean.
I'm rooted on OxygenOs 1.0.3/Android 5.0.2.

Galaxy J700T Black Screen Non Responsive, Flickering, Boots Normally

I've come up with a problem that has perplexed me on my Galaxy J700T. I've looked everywhere for solutions, but none have worked.
The phone's screen will go dark after it boots, but will show the lock screen for a split second. The screen will sometimes flicker back to life for a moment, but then go back out. This can happen a few times. Sometimes it will go back to the same screen, but sometimes it will show the lock screen. Sometimes it will show the lock screen on a flicker, but then go back to whatever normal screen or app it was on before, when I hadn't unlocked it. This only happens when it was on that screen previously though It sort of Flashes the lock screen I suppose you could say. The phone's screen seems to be unresponsive when it's black.
I'll start with what I know:
It isn't solely a hardware issue - The screen does turn on when you first turn on the phone. It shows the boot process. You can boot it into Download mode and the screen will stay on. You can also boot it into Recovery mode and there will be no problems with the screen. The phone can boot normally and the phone will show the whole process. The problem is post boot so I find it hard to believe it's solely a hardware issue, otherwise I should have these problems in the other modes too.
The screen isn't always off - I've managed to actually catch my phone displaying messages at the bottom of the screen for a split second. One such being that it has connected to the internet. This will show for a split second, while the rest of the screen is still dark. The screen appears to otherwise be dark with no light, looking as if it is off.
I've looked into this black screen of death issue I've heard about. I'm not sure if this is it. I've never had the issue before with any other android device I've had. It doesn't seem like it when I look at descriptions of the problem.
I have put the phone through Factory Reset, which hasn't worked in stopping the problem. As soon as the welcome screen shows up to set up my phone, it will go black again. I cleared the cache. I Cleared all data and reset it. Rebooted it in different ways. I did root it.
Would anyone here happen to know what's going on or have any possible solutions?
