I bought digitizer for y Xiaomi red rise 1s. I replaced it, everything carefully checked, and tried to boot up.
The thing is that phone boots, the manual button work, but the screen doesn't come to life.
What can I do? I heard that it can be a problem, and the HARD reset can help, but I am not sure?
Is this a good question?

Hi,
1) Check FPC has been connected properly
2) Check the reborn cable whether any sign of damage
if fault not solved
re solder FPC using hot air or IR if fault remaining same check the back light voltages : it should be 18V-22V if voltages not present check the back-light driver
