Friend brought over his punch-out yesterday for me to try to fix. He thought it was bad monitors, but his monitors actually worked(they need to be adjusted).
But he did have a problem. The top monitor was missing blue. When he brought it over the top monitors color inverter board was removed off its pins and its back was lying on the monitor frame. (He did transport the game on its back, so it could have fallen off on the ride.)
I checked the top monitor and it works fine. Traced all the wiring back to the video board and its fine. I would guess its a bad blue color prom.
My questions are, what isthe chip location of the blue color prom? Can the chip be taken from another nintendo board (I have a few dk, dkjr, popeye, mario ect).
If it can't be pulled off another board, does anyone burn the color proms?
