BAM! Paulb_nl nails it.
Yea I just tried the DIN Yellow RCA and the normal RCA – NO SYNC
Changed those settings? bam. for both and the CSYNC cable. (even though its running sync on composite at the moment)
I’ll put the CSYNC mod through again and see how it goes.
Seriously thank you so (and everyone else) for taking the time to troubleshoot this with me.
