PS4 CUH-1116A the drive not taken disk

hi have this problem the disc is not taken from the player, i have the beep sound when i pressed the button . i have changed small board bdp-15 but nothind the disk non enter on the bay help please

Not sure if i understand correctly but the original circuit board that was attached the bluray drive of this ps4 is married to the motherboard.i think all original phat versions ps4 bluray drives and motherboards are linked. If entire bluray chassis is changed the. Circuit board of the old drive must be ported over.
