I have a ps4 thats been taken apart by someone else and everything seems to work except the disc tray the console takes and ejects the disc easily but it doesnt seem to be spinning the disc and always comes up as unrecognized disc.
Solutions I have tried:
-Replacing the disc drive with another (Yes I correctly swapped daughterboard)
-replace ribbon cables that looked faulty
-inspected ribbon cables for any damage
Does anyone know what part of the motherboard is responsible for disc spin and what area should be checked?
