I have a rooted Samsung j7 prime with stable black panther ROM and twrp recovery 3.2.2
I broke my LCD so replaced it with another one by my own.
There are 2 problems:
1. The screen doesn't go on when the phone starts up, but works fine (touch and display) after it has successfully booted up.
2. I can't see anything when I enter the recovery mode. The screen goes full black, but is responsive, as it vibrates on touch. On pressing the power button twice, the screen lights up but just for a fraction of second.
The key points are that the LCD and motherboard are fine as I can operate the phone(yes, I can see the display now) once it is switched on. The only two places when the screen goes black is during startup and when I enter recovery mode.
Can anybody help me out. I don't want to be stuck where I have a rooted phone but am unable to use twrp

So recently i start flashing and using langthang's MIUI roms and keeping update and flashing all his new release rom. so couple day ago all of the sudden, i don' know what causes it and how it started it. my red button on far right. pressing it turn on and off the screen.so now when i press it to make the screen go back on from off mode. after i pressed the button the screen light turn on and the lock screen is there but when i touch the screen and try to move the ring(pyramid lockscreen) up to unlock, but the ring is not moving, it like there is no touch screen ability to my phone's screen.
but when i use the green button far left, the button usually to use phone. that button doesnt turn off the screen but it just turn on the screen, this button is working normally. i can move the ring up to enter the main screen.
the screen isnt cracked or any thing, but i do have a protection layer over it which been there since i got the phone and never got this problem before.
what do you guys think my problem is and how can i solve it?
thank you!
I have the ATT S4.
I used the twrp app to flash a new recovery on my phone. I downloaded the jflteatt and flashed it through the app. Worked all day til the evening that i needed to reboot it. It won't boot up anymore.
I take the battery out, and put it in and then galaxy s4 splash screen comes up. but goes away quickly. I take the battery out again, and put it back in holding volume down, it brings up a screen saying "do you want to install custom OS?" "press volume up for yes, or volume down for no" but quickly the screen goes black again and i can't do anything, even if i try and press for yes.
I take the battery out, and put it back in holding the volume up button. I boots up to the galaxy s4 splash screen with "booting into recovery" in blue letters at the top left part of the screen, then the screen quickly goes black again and i it doesn't do anything.
Is there anything else I can do?
thanks for any help

Unless you can get it to stay in download mode, no. Does it show a charging battery if you plug it in?
Sent from my SGH-I337 running Light ROM
So randomly, my screen stopped working. I cannot figure out what caused it.
it was fine earlier in the day, then i left my phone completely alone for a few hours, and come back to it to find the screen not working.
When i wake the screen, there is a little bar of light that flashes on the screen, it is maybe 3mm wide, and extends the width of the screen, it flashes, then disappears, and my screen remains pitch black.
is this hardware related?
the only thing I can think of software wise is that my phone is rooted, has exposed module installed, and I am running wanam and gravity box
removing the battery and putting it back in does not replace the issue. as soon as the screen awakes and tries to show anything, the orange bar flashes and disappears.
Start by seeing if you can boot to download or recovery mode. This will bypass most software related issues.
Remove your phone battery for ten seconds. Then press and continue holding keys in this order, volume down, home and lastly the power key. After about five seconds the phone should boot to the Download screen and display some system information.
If so, then try clearing your cache from recovery mode, booting to safe mode or flashing a 100% stock firmware from download mode to recover. If you can't boot to download, recovery or safe mode then it would appear that you have a hardware problem.

Hi all
I just get the white light and blank screen (no logo, no bootup screen, nothing) on during my tablet boot up. I have tried everything (Power + up button, plug and unplug the power with hold on the up bottom etc) I still can't to get into recovery (factory) mode.
Every time, white light just on and off late. I have also tried to put aside the tablet for few weeks to use up all the battery and restart. Same happen.
Any suggestion I can get in the recovery mode ?
Thanks to all for your answers!!!!! :fingers-crossed::fingers-crossed:
Hi, I have recently purchased a Mi 9T and everything works fine with the phone, but I have this bug, that I didn't see in any post from this forum.
Every time the screens goes black (sleep), it doesn't recognize any input anymore. The phone still works and I can receive calls, notifications and so. I can turn on the camera, make screen captures, and everything, but only because I can do this with the volume and power buttons.
I tried Flashing the device, but when I get to the recovery screen of TWRP for the first time (where you need to make a swipe) the screens goes black for a second and doesn't let me do the swipe.
Any ideas of what the problem can be? (and the solution if it's possible).
If not just press the power button again ...same things happens to me, once i rebot into recovery it goes black and nothing happens, then i need to press the power button to "unlock" the screen again.
had similar experience: sometime after I lock the device (by hitting power button) and screen goes off, it input my finger on the fingerprint sensors it does not recognize and unlock (not even fingerprint animation actually). Other than this I can still hit the power button so that the screen lights up and then unlock with fingerprint.
But, this is just sometimes, not always.
