Hey guys I just got a suuuuper cool Sega Space attack. It plays and sounds and coins up just fine but in at a loss at the display. It has vertical lines running through it. I have the NEC chassis a cap kit and tried adjusting all the pots with no luck.
I can't find a manual to test power and I have no idea what the pots do on the board by the power supply.
I also reflowed all connections and reseated all the removable chips with no difference.
But I'm thinking it may be chips not power?
Any help on where to begin..
Hmm photo upload is not working. I'll try and post pics soon.
