5.2.1 DVD Engine
The DVD engine is a non-repairable component. Hence, it is
necessary to determine if any fault condition of the player is
caused by the DVD engine before replacing it.
The engine is a stand-alone system, an integrated unit of Slot
loader and servo board, which does not need to be connected
to the decoder board to perform it basic operations. Once a
stable voltage is supplied to the engine,some mechanical
movement will be observed. Hence, to determine whether the
engine is faulty, remove the 40 pins flex cable and observe the
mechanical movement. If no mechanical movement is
observed, the engine should be faulty and it should be
reconfirmed with a working engine.
The Slot Loader has an optical unit consisting of two lasers,
one for CD with a wavelength of 780 nm, and one for, DVD with
a wavelength of 650 nm. If any one type of disc (DVD or VCD /
CD) cannot be identified by the player, it can be sure that the
fault is due to the engine.
