    What could cause this board in particular to not sync properly? Any ideas what could be different internally to all of my other JAMMA edge boards?

    Somebody should scope the sync signal coming out of TMNT based boards. I recall these have been reported not to work with original OSSC either which uses completely different video frontend chip. If you disable framelock and change to AV1_RGBS input from test pattern when the board is on, is there any indication of syncing (OSD status flashing etc.)? It would be strange if the frontend just reports no sync, especially if you have tried lowering the Vth.
