[Q] Screen is black but still reacts - General Questions and Answers

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

Screen is black

At work yesterday my phone was fine..I pulled it out of my pocket during a break and the screen wouldn't turn on..then I noticed the backlight was on and I can feel the screen vibrate when I hit where the home button should be but no picture. I am able to hear notifications and use my moto360 to make phone calls etc but no picture just a black screen and backlight is on.. Using my nexus 5 currently but wondering if anyone else has experienced this..T-Mobile said they would replace it under warranty.

Hello.
I have the exact same issue, I got a phone with a broken screen, it only had black backlight, then I changed the screen with a new one and still the same thing happens. Tried with two screens.
After replacing the screen I repaired the software via Sony PC companion, but it didn't work.
Does anyone know what the issue is here? Is it a dead motherboard or something else? Just so that I know to stop trying to fix it.
My unit isn't under warranty anymore because it had physical damage so replacing it via Sony is a no go.
The phone boots fine, I get audio reading of menu options for the initial setup, even the touch works, I can select options but I have no image, only the backlight.

[Q] Touch Screen Unresponsive plus White Horizontal lines

Hey guys and gals,
I have nexus 5 that is just about a year and a half old. Every now and then, when I wake up the phone from sleep, the touch screen becomes unresponsive and I see white horizontal lines running across the top. I have tried restarting the phone, resetting the phone to factory. The problem still persists. The only way I get the lines to stop from showing up and get the touch screen responsive again is pushing down on the screen hard at random location.
I have attached a video of the problem I'm getting. https://youtu.be/CzgZ1bcN1Lk
I'm suspecting its a screen issue and I need to replace the LCD panel, Digitizer, etc
Any help would be greatly appreciated.
Thanks!
You need to replace the digitizer (if I'm not wrong), I've encountered this issue before on my older phone.

[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.
