Hi D/T

Guess you've checked P/S D893 for S/C and link J130  (recent thread) - Chris.

Hi,
If you've changed the main pcb, and power-supply, and all the supplies are correct,
I would check the continuity of cable from the PS to the main PCB, etc.
Have you tried using a scart input, to check if there is sound?
Regards
John.
