H Folks,

Have one of these in where sound is present via Scart but there is just a brief snowy flash RH side screen. Replaced P/S as I had a good one - no different, and a constant Green led.

Checked voltages, some were OK but no VS. Thought buffer chips so checked fets - checked them all - No shorts.

Run out of ideas - Any thoughts - Thanks - Chris.
