Yeah I've checked all the wiring before, with jamma and the dedicated system with 4 different boards which leads me to think its a hardware problem (capkit, ic2 etc.)
I just finished installing the capkit (11 out of 19 capacitors .. the other 8 werent compatible with my board, neither was the cap chart though. Even though I got a mtc 9000 cap kit..) and will triple check the polarity on them again tomorrow before power on - I'll post here what happens.. And also if I need any more help with the sync problem
