After splash screen, screen blank but phone sinks with BT & capacitive lights active
Today I tried to update my phone to the newest firmware (I think it was .210, but I know it was from August 5th on firmware finder...I know its a long time to wait to update, but I started a new job, moved to a new city, etc. so things have been super crazy). Unfortunately, after flashing with EMUI Flasher, the phone rebooted and then got an update failure. I restarted the phone and waited but the screen was black. However, my smart band paired and if I press the power button, the capacitive button lights turn on, but the screen is blank/black. I have tried rebooting, both regularly holding power for 20 seconds as well as holding the power key with volume up and then volume down. I can reboot into a recovery of sorts and tried to wipe cache and restart, as well as boot into safe mode, but both result in the black screen from before. I can also boot into fastboot, but don't know what I could do to fix this.
Any advice as to how I can save my phone would be really appreciated. I'm really hoping I don't have to wipe the phone.
Please help me!

I can see the screens but it constantly flashes & isn't always responsive. When it updated I saw it update all my apps then I think it rebooted (I have kids so i was distracted). If it sits it will dim then go black screen, then brightens back up, Kies will connect to it for several seconds then loses connection. What can I do?
Factory reset? I do that by powering off then holding in up volume button and the power button at the same time correct?
looks like the factory reset fixed issue
Hello all,
When i try to boot my phone, there is only a vibrate but the screens stays off (not black, there is no backlight, the screen doesn't turn on).
Except when i press power + volume up, then i get the screen to go to recovery, fastboot, or boot normal but it doesn't matter which i choose, after that the screen goes off again.
Does anyone have any suggestions? Luckily i swapped phones a day before it broke so i wouldn't lose important files but it would be nice to be able to recover them.
Thanks in advance!
It all started 2 days ago, when watching a clash of clans replay the screen turned off for the energy saving thing. I pressed the power button to bring it back, but the screen didn't turn on, i could hear the game sounds, and the touch screen was working, after the replay ended i was able to tab the buildings in my village and hear the sound they make. I pressed some random combination of buttons, i think its power+volume down and the screen turned on. It happened a second time during that day, and i was able to turn the screen on again. But the day after that trick didn't work and the tablet was stuck with a black screen.
I tried a factory reset, but the menu for it wouldn't appear, the odin menu by the other hand worked fine. The recovery menu should appear when with the tablet turned off you press volume up + home + power in that sequence, and releasing the power button at the samsung logo screen. But the menu never appeared, so i navigated it blindly and i think i managed to reset it, at the next accension i was prompted with the personal information field, name, google account, time settings etc..
The phone started again, with all default settings, and all my files where gone (so im assuming the factory reset worked) but when the screen turns off it doesn't come back by pressing the power button, it comes after trying a few combinations (and again i think it is power + volume down and wait a few seconds).
So im worried it was all in vain, also the screen brightness is bugged, and changes the colors, the become reddish with low brightness and some colors disappear.
Edit: After i let the screen turn off for the third time today, it doesn't come back on. So im back at the black screen...
I have never used any modifications of software. Only used stock firmware.
My coffee was spilled a little on device. Cleaned it immediately.
Then I got a freeze after boot up. I could see the home screen, but touch screen not responding, "Menu" and "Return" lights continuously lit and not responding. The removal of battery or long press of ON/OFF button was the only method to turn off. But the battery % shown on screen was correct each time. If I called the device, it was offline.
I connected the phone to my computer and it was recognized by windows. I did not transfer any files to phone by odin, but I have Odin application.
I used 3 button combinations to wipe cache, then boot up, but no change.
Then I used 3 button combinations again to return to factory settings and wiping everything. Now I get a solid screen where I need to select language but the menu and return lights a on continuously, and the touch screen does not respond.
So far, I can see that my three hardware buttons, on/off, volume, home buttons are working. Phone also was returned to factory defaults. But the problems continue to be the same. They are: no touch screen reaction, continuously lit menu and return buttons, home (OK) switch not working after boot up.
I have started to think that there might be a hardware problem. I have downloaded the service manual, can solder things, even have a microscope if needed.
Can somebody guide me to check where is the problem please?
Good evening folks,
I am in need of help. I've been having issues with my tab S3 (SM-T820) for the last month or so. I notice that when i let the device charging over night, after i disconnect it, the screen goes black. I know the device is on, since the button lights are active. I've performed forced reboots (holding power + volume down buttons), and screen remains black, but device is on. I've performed hard resets via the odin software and the firmware, and yet the screen remains black (again, device on, button lights on). If i connect the device to a charger, when the screen is black, the screen turns starts displaying a black "speckled" display (black screen with color dots everywhere). When i see that, i start pressing the power button, turning the screen on and off continuously, until i finally get the screen to appear. Problem is that once i turn off the screen (not the device), again the screen will go to black and not appear anymore, until i keep messing with the power button again. I'm finally at lost since i sent the device to squaretrade for warranty support, and they keep sending it back as repaired (all they did was a factory reset, which is what i have done via the Odin software). Any idea on what to try next? I have though about disassembling the device and verifying the display cable is correct, but just seems irrelevant that it could be a hardware issue since eventually the screen does come on again (after trying countless of times), plus, i don't know how to disassemble this thing. Any ideas or recommendations?
Thank you in advance
