Purpose of Dealer Script
The dealer script can give a diagnosis on a standalone DVD
player, no other equipment is needed to perform a number of
hardware tests to check if the DVD player is faulty. The
diagnosis is simply an "error" or "pass" message. No
indication is given of faulty hardware modules. Only tests
within the scope of the diagnostic software will be executed
hence only faults within this scope can be detected.
