2. Connect a digital multi-meter between TP93 and TP95
(negative to TPQ5).
7. Confirm
that the voltage

reduces to 0.06V
when the DC voltage at TPQ3 is 10.4V.
8, Connect a 1.2k ohm resistor between TP96 and TPY7,
and confirm that the picture disappears (ADDP operates)
a few seconds after the voltage at TP93 is reduced to
10.2V.
