I have been looking for ways to fix a black screen on a GS3, and now asking here. I was given an S3 to try to get the screen to work. When you boot it up, the leds work but not the screen. I can connect to a pc and see the phone. Is there a way to fix this (through buttons) or does it need a new lcd?

One of my friend tried to root his phone using odin and a firmware for version 9023 while he has a Nexus S GT-i9020t. I've been looking for some hours, and I couldn't find any solution for that problems.
This post has similar symptoms, but still no answer: http://forum.xda-developers.com/showthread.php?t=1436199
Symptoms
- No backlight at all (seems to be a problem version amoled vs slcd, as I could read)
- Screen is upside down (but buttons, keyboard, etc still react correctly, only the screen display is upside down, so you get to have two phones next to each other to press the right buttons...)
- Can't get into download mode to flash using Odin and the correct firmware. When you hold both volume buttons and plug the USB cable, you get the first attached image. Green lines, nothing else.
What it can do
- Phone can get into the bootloader, but screen is very dim, as you can see in the second screenshot
- Phone can boot normally, you may take screenshots, place phone calls (while guessing numbers), receive phone calls, but the screen backlight stays off, so it's pretty hard to read anything. Tried to get to the display settings to play with the luminosity, without success.
- No problems using adb to send commands to the phone, or using fastboot to flash the device.
What i've tried
1. Downloaded original firmware image from Google, and tried flashing the device using fastboot. Tried 2.3.6 and 4.0.4 for Nexus S worldwide (i9020t) - over here: https://developers.google.com/android/nexus/images . Still no backlight.
2. Tried the One-Click Unbrick for Samsung devices. Installed drivers and everything, the tool return the result Success, but still can't access download mode, or fix the problem.
It looks like the graphic part of the phone is messed up, and i've got no idea on how this could be possibly fixed.
Any help would be greatly appreciated !
I think your AMOLED Screen just died or is going to die. If it is still under warranty, get it replaced. If not, look on ebay and buy a replacement screen. Its a do it yourself procedure. Or take it to a phone repair shop and they'll do it for you.
It's not under warranty anymore, it's 1 year and 2 months old.
I doubt the screen died, since problems started when he installed the wrong firmware. Can a bad firmware cause physical damage to the screen ?
Hello,
My phone was waterdamged and stop working completly.
I opened the case and tried to dry it.
after 48 hours of trying various stuff, there is blank screen, but:
1. The phone is booting fine, charging led is working.
2. Using Wondershare-Mobilego, i can backup all the content.
3.The touch interface seems to be working fine, i can see the menus via mobilego duplicate screen (can open the sms box or whatsapp and etc.)
4.Incoming messages keep coming...
I`m so frustrated that i`m using the phone blindly or like remote desktop.
Is it software of hardware fault?
THANKS

After water damage you can only expect hardware damage. to verify - when turning on the device, do you see anything on the screen? you can also reboot to bootloader (via the key combination or via the command adb reboot bootloader (and to reboot back to android use fastboot reboot).
If the bootloader shows nothing, 100% hardware (although there is really no need to check, probably is). You can try changing screen, but the problem could also be in the socket (but I think if it were the socket the phone would not even boot). Worth a try.
Thanks, but no good...still blank screen - no display.
As i mentioned, the phone is functioning well (as seen at duplicate screen).
When you offering to change screen, you mean the lcd touch digitizer only?
I don`t need to buy the screen itself, right?
(I can`t parse outside links yet from ebay)

I mean the LCD itself. If touch is working, the problem is the LCD itself, not the digitizer.
You right, it seems that the touch working fine.
You think that a LCD display screen replacement would be the best try? can you paste a link from ebay please?
dropped my tf101. Now when I try to boot the katkiss revolving circles dont stop going round and round. I am able to get into twrp though.I am aunable to restore because I never did a backup. Also I was getting red artifacts all over the screen. I would lightly tap the underside of tf101 and it would make the colors change dramatically on the screen and show red lines going across the screen. after tapping the tablet a couple more times the display colors are normal again but it still wont boot. What can I try?

If you can get into TWRP you need to download the latest Rom and Gapps to a PC and install them onto your sd card) assuming you have one - if you don't ? my advice is get one (or two or three). Put sd card back into tf101 - boot to TWRP and then wipe all (see page one of the KatKiss 4.3 developers topic on this for exact wipes - oops just took this from Timduru's page
Go to recovery
Make a full wipe / factory reset (you can skip this step if you're already on KatKiss-4.3, if ever you encounter a problem do the full wipe and try again before reporting )
Format /system
Flash the rom
Flash optional kernel
Flash gapps
Wipe cache/dalvik
Reboot
As to the flashing of the screen - the fall could have done something to the video drivers hardware (but fingers crossed)
Good luck

after putting in my micro sd card i saw there was a back-up on it. I was able to restore from it and boot successfully. However my colors were off. . shaking/flexing/jolting the tf101 results in things like the whole screen turning blue green with lines across it. I'm not seeing any red lines anymore and now the olor red is missing all together. This makes white look blue and red look black. I was able to confirm HDMI out to tv still produces image/colors correctly. I'm afraid hitting tablet anymore won't bring red back and kill image entirely. Now since its fall yesterday a light tap on TF screen results in screen to go dark momentarily. Any chance this can be opened to fix missing red? Another problem since fall is vol down button is not functioning right. Seems like its stuck depressed. Is the vol down button necessary for advanced options?
Everytime I reboot I get bootloader white text in the top left of screen thats only supposed to show when vol down is pressed. Then the next screen says press down -vol for wipe option but I it doesnt move when i press vol- ( however I think I can actually initiate a vol- button by flexing the pad. Sounds strange right? Anyway I gues that means I can pick the wipe data option from that screen if i have to. after that select android/ data wipe screen I notice now every time I boot up in bottom left it says "SAFE MODE", what does that mean?
Your VOL buttons are stuck down. I am not excactly sure how to boot to safe mode, but it is due to one of the VOL buttons being pressed during the boot up process.
I would suggest taking the bezel off and trying to carefully bend it so the buttons move freely. I wrote a guide for it here: http://www.transformerforums.com/fo.../10501-rs-guide-power-lock-button-issues.html
I was able to unstick vol-, but after hitting tab a few more times trying to get red back, now there is nothing on display. I confirm hdmi output is still working. Anyone service these? Otherwise i guess i get a bluetooth keyboard/mouse and use as desktop PC?
Something i can fix myself by opening?

Most likely it is a loose video or backlight cable. Open it up and take the bezel off per the guide I posted. Then remove the back cover. There is one screw on each corner and then 3 on to and 3 on the bottom between the screen and back cover. The video and backlight cables are in the middle near the charging port. Make sure they are properly seated. Power it on reassembled to see if it works.

I can tell you that when i press power rhe screen does light up. Its just grey screen. Does that mean back lighting isnt the problem and im wasting my time opening tab?

That means the video cable is loose or that the video card is bad. Since it works via HDMI, it should be a loose video cable. The video and backlight are separate cables.
I tvook the case off. Im not sure what to do. Ive got some basic colors on pad display again but it wont boot. Circles still spinning. I cant ssem to enter twrp either. I tried holding vol down power ro reboot and i quickly see green label on bottom of screen and then goes dark. Would twrp be visable from hdmi out?

Here are some pics I took on the bottom side by charger. what should i reseat. Nothing seems movable .can you tell me how i can get into twrp since i currently can't boot. I tried holding vol - and power but i didn't see opption to hit vol +. I tried to hit vol + anyway but i just got a grey screen. I tried holding power vol+ for 10 secs. to cold boot. still just spinning katkiss circles. Do i need to get into APX mode (hold VOL UP and POWER for about 10 seconds and use EasyFlasher to re-flash TWRP?
Bumping thread
What button combos can i try to get back into twrp since i currently cant boot or enter recovery? Is it the multi color wire ribben that i should be adjusting?

I believe this is the display cable that tends to come loose after being dropped, if not that one, a similar coloured and positioned cable, I did have a video showing the exact procedure but can't find it atm
EDIT - Found it

thanks for the vid. I was able to get display working again including red so this will work even if the problem is your display stops showing all colors and starts showing lines and other artifacts. It seems I answered my own question. you cant use twrp with hdmi only. native display only. Although it could be the commands would still work though you wouldn't be able to see what your doing i'm guessing? so in twrp i did a second recovery of my 4.2. katkiss backup since dropping my tf since I was again just getting spinning circles when booting and I'm now able to boot again. Hopefully this doesn't keep happening where tf wont boot and I have to keep recovering. Seems like dropping it may have done more than mess with display?
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.
Hi everyone, I have the following problem.
Yesterday I broke the display of my Samsung Galaxy A7 2018: the screen is completely black and obviously the touch doesn't works.
I tried to connect the phone via ADB to my linux pc and until yesterday I was able to connect it even if it wasn't authorized to perform any action.
I tried to restart the phone and now I'm not able to connect it anymore via ADB, maybe it's in some strange status that I can't recognize.
Considering that I can't see the screen and only actions I can take is via phone keys (vol +, vol - and power), how cam I try to restore the phone and (if possible) try to see the screen via an externet app/software like [email protected]?
I would really appreciate any help
Thank you very much
Im not sure if there is an app for that but for me its so hard to use it since the screen is broken. You need to bring it to the cellshops.
