Title: Wells Gardner Monitor not turning on
Post by: ryanhaws on July 22, 2007, 09:52:30 pm: I bought a Golden Tee 99 game but the monitor won't power on. It's a Wells Gardner monitor. The sounds, marquee light and fan turn but not the monitor. The yellow and green lights on the game board light up. I plugged the game board to a different jamma game and it plays normally. There is no light to the neck of the monitor at all (in the filaments?). Please help me troubleshoot this. What should I do first? Thanks

The only problem I have is after replacing it, the fuse blew as soon as I powered up the game. Mine is a "Skins Gam". Ill be interested in what you find.

First thing to do is GET THE MODEL NUMBER OF THE MONITOR!

Post by: ryanhaws on July 23, 2007, 09:27:02 pm: The deflection board is "p963" and the monitor has WG 1405968 on it. I checked the fuse and it's fine. Where do I start?

Post by: ryanhaws on July 26, 2007, 09:48:53 pm: Yes, the deflection board says P763. Sorry, that was a typo. Okay, what should be done first?

Post by: ryanhaws on July 30, 2007, 09:46:02 pm: okay I discharged the montitor and removed the deflection and neck board. I looked for places that the solder may have come loose. I only found one joint that needed to be resoldered. I fixed that but still no change.

Post by: ryanhaws on August 04, 2007, 01:32:08 pm: I believe the neck board is working properly. The deflection board is not through. What are the most common things to break on the deflection board. What should I check first and how. Thanks in advance to anyone willing to help!
