I was using the continuity checker on my multimeter. It beeps if there is continuity.
If I set it for Ohm’s there is nothing between the CSYNC line and the ground.
I had rolled back to composite/revered mod before, but just did it again and… no sync.
Something else random – I just tried using the sync on Luma from the S-Video port to the CSync Pin on the din and same thing no sync.
Bad Cable? Some sort if setting I need to tweak in the OSSC?
