Picked up this nice complete Defender today for $175 with a brand spanking new WG monitor! Anywho the guy said it had a ram error and added a ram chip to the board and now it just gets vertical lines (see pic). It would appear the boards were rebuilt in 2004 hence the Eldorado games warranty stickers. I tested the voltages and they are at 13.2 and 4.7 volts and I'm not too hip with these Williams boards so any ideas??
Update...All 4 LEDs light up then go out so it is most likely a ROM board issue but I can't go to the diag screen to run the tests. Possibly a bad ribbon cable??
