Hantarex Polo3 Sync Problem

I have wired so many cabs that I accidently managed to mixup parts- and solderside for video on the jamma connector... now i did the wiring right, tested continuity and all but the screen won't sync. I tried combinations of hs only, hs and vs on cn7 on the monitor, i'm afraid i'm missing something... or i damaged it when i first powered on with the mixed up wires.
can anybody take a look at the video and tell me if this looks familiar to you?
it's a hantarex polo3/15kHz 14" screen.
thanks!!!

if its a multigame pcb then use pin 1 as video ground or link 14 and 1
that looks video ground missing rather than sync issue

that's what i was guessing but haven't tried yet.
yes, it's one of those crappy 60-in-1.
i'll report back when i added ground to pin 14.
THANKS!!!!!

This was pretty hard...
I rewired the thing four times, used different PSUs, changed the ground-wiring and and and...
In the end... the darn pcb was faulty, replaced it and everything was in working order.
Thanks for the advice with the video ground though!
