I just picked up a dead Karate Champ. After a couple of quick fuse checks I found one to be bad so I replaced it. The Marquee lights up and the game plays blind. I checked the monitor which is a WG 19 K4900 there is no glow in the neck board, the fuse on the board tested good and I checked to make sure power was a go as well. I tred reseating the neck board and still no glow and no monitor. Any ideas? Thank you for your time and talents.
