Video Game Repair/williams stargate


Recently purchased this machime not workingfor $50. I replaced the fuses and plugged it in. The very first f u se, a 3 amp, on the board where the plug runs to blew. I replaced it and got the same result. I disconnected the power supply board and the monitor and still get the same result. I plugged it in without replacing the fuse and fpund that the plug is not the issue. Npt sure what the board in question is called. It has 1 fuse. Its 3amps. The power cord runs directly to it. Not sure what my next step is. Thanks for your help.

Hi Chad!

It sounds like you've got a short on your power supply board. This typically is the bridge rectifier, which is the grey square near the middle of the board.

It might be easiest to install a switching power supply in place of the old linear power supply.

This is the best one on the market:

Look in the power supply section for the Williams kit. $39 and you'll be all set!

Good luck!

I can answer questions regarding coin-operated arcade game questions down to the logic board. Error codes, erratic operation, dead boards, I can help with them all. I can help with video monitors on a very limited and basic level only.


I have spent nearly 20 years as an avid arcade collector, and spent nearly 10 of those years as the lead tech for a large arcade operator, doing work for manufacturers and other coin-operated amusement companies around the globe. I maintain a good sized collection of arcade games, as well as a large inventory of spare parts for a wide range of arcade machines.
