Hello!
I replaced the screen recently on my Lenovo Tab m8 HD and now when I turn it on, or do a forced restart by holding down the power button, the backlight turns on for a millisecond and I can see the Lenovo logo but then the backlight turns off. I can see the icons and everything when I hold a flashlight close to the screen so issue is the backlight. I replaced the old shattered screen back and it does the same with that one as well. So I am not sure if the ribbon cable got damaged during replacing the screen or is it a problem on the motherboard with the inverter circuit. Help needed.
