I've been trying to get rid of the annoying hum bar problem. I replaced both fuse blocks, new fuses, reflowed solder, new connector, and capped the k4600 monitor. Plugged the pacman in and everything worked great except the hum bar was still there. So I pulled out the pacman board and replaced only three caps from bob roberts pacman cap kit and decided to turn it on to just see. After I flipped the switch now I get this faint red screen and nothing else. Did I kill the pacman board somehow?
I replaced both the 10000uf 10v caps and the one 2200uf 25v cap. If I remember correctly.
