BD Drive is controlled by BP1 IC through the drive IC ( IC55006/Motor, IC55005/LD ).
BD Dive
BD Drive outputs RF signal from Disc to the BP1 IC (Peaks Pro2.).
The RF signal is processed by BP 1 and decoded to the Video and Audio signal.
This BD Drive needs pairing with the Main P.C.B. for repair (replacement).
