Working on a Gorf that has starfield upon start up and that's it. Coin up the game and it goes to a blue screen. Sounds like the game is playing, but can't see anything but a solid blue screen.
I took off the RGB Interface Board Assembly and resoldered the header pins. Didn't see any cracks in them.
Just looked at the game for a couple of minutes. Any ideas on where to start with this?
Thanks again.
Edit: Checked voltages, reconnected all the boards, and reseated all socketed chips. Same outcome, but now greeted with an all GREEN screen. Would it be the TBA530? How would I check this using a scope?
