I presume you have tried obvious things like rebooting or trying to get into recovery mode?
Otherwise it may be a blown LCD panel, a blown backlight, a faulty or loose cable or a mainboard fault.
If you look really closely at the screen in varying light conditions you might be able to see the display if it's only the backlight, but that would still need the panel replacing.
There is a teardown video on YouTube if you need to take the phone apart.

A couple days ago the screen on my transformer stopped working it would no longer display anything. I've restarted it many times and nothing ever displays not even the boot sequence. It displays perfectly via hdmi and the touch screen works there is no physical damage to the tablet. It was running prime 1.5 but I have re-flashed it back to stock 3.1 hoping that it would fix the problem but it did not. Has anyone had any similar problems and if you have were you able to resolve them with having to RMA. If any information is needed like logcats or anything let me know and ill be able to get them once I get home from work.

Did you check the screen brightness settings? Did you try turning it on in a dark room to see if the backlight still works? Seems odd to me that you see nothing yet you can still use the device's touch screen if connected to an external display.
yea ive tried adjusting the brightness setting/ turning on auto brightness both things had no effect. When it first started occurring I could faintly see the asus logo when it was turning on but no matter how dark it is now I cant see anything on the screen. thanks for the help hopefully we can figure this out.
Shine a torch on the screen (in a fairly lit environment) and see if you can make out anything on the screen. If you can see screen content then it means the backlight (or the inverter) is faulty. In any case this sounds to me like a hardware fault.
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
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
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.
When i receive a phone call the screen turns off when i put it to my face, but when i move it away the screen never turns back on. I can't hang up the phone i end up having to restart the whole damn thing. Anyone else experienced this?
Yes I have the same issue going on now. I'm trying to see if there's some kind of manual over-ride or if the phone can cycle the screen on and off with just the side button / power button click alone. Would be fantastically helpful.
Mine is not dirty, it is broken, I have tried cleaning it with no avail.
