When the main power switch is
set to ON, the main power/video
reception LED lights in the order of
red -> green -> red
and flashes six times.

Can a relay

sound be heard after

the main power switch has

been closed?

Perform

a continuity check between

pins 1 and 2 of the connector E13

and earth, and check for

a short-circuit.

Perform

a continuity check between

pins 5 and 6 of the connector E13

and earth, and check for
