My note 8 screen suddenly stopped working, no drops or known damage of any kind. Just a totally black screen but everything else seems to work, light blinks, it rings when you call, everything. A repair shop that was planning to replace the screen said the screen is ok but the screen power chip is bad. Does anyone know of this is on the logic board or daughterboard? Also, if i replace the logic board, will i lose my data?

Brady Martin “if i replace the logic board, will i lose my data “ yes you will. Your data is stored on a memory IC which is part of your logic board. Not sure which “power chip “ the person you took it to is referring to. U900 is the display PMIC which, in principle could qualify what that person is suspecting. It is on the logic board. I’d suggest you go ahead and follow the troubleshooting as outlined here
