SYMPTOMS
No Operation in DVD Mode or C-81 error is displayed.
CAUSE
Transistor Q002 malfunctions.
RESOLUTION
Replace Q002 with HOUSING (Q002) ASSY which consists of a higher capacity transistor (2SB1375), and socket. Also replace R011 (1K ohm) with a 470 ohm resistor.
New part number for the transistor is X-4954-896-1.
Resistor part number is 1-218-949-11.
The resistor is about the size of a flea speck. Better to just solder a 1 kOhm 1/8w resistor across R011.

P.S.
These models are so unreliable, it is very possible you will work hard to get it running, then the customer will be back in a matter of weeks with a similar but different problem, and of course it will be your fault.
