So sick of looking at my totally restored Hulk just sitting there with nobody to play with him. Game will not boot, but GI and BB light up. Loud humming through the speaker. No displays, although they do flicker when you turn the game off momentarily. The guy I got it from rewired some of the bottom of the PF, but for the most part it looks OK. There are a few wires not connected (looks like they belong on one of the bulb sockets?). Photo below. The fuses all test good, and MPU appears to be getting the proper voltage. Also took a pic of the transformer board. Don't see any other "loose" wires.
Is there something I'm missing? Any help would be greatly appreciated.
