This model has the self-diagnosis function for the VIDEO and
AUDIO decoder sections.
Immediately after the power on, the self-diagnosis function searches
each operation of IC’s around the mechanism control microcomputer
(IC701).
The results can be checked by connecting an oscilloscope to TP709
(LED) of the VIDEO board.

Note:

The LED for check (D701) is mounted to some sets

(FORMER TYPE). In this case, confirm the lighting
condition of LED.
