Hello..
I'm hoping that someone out there is familiar with the old Star Trek SOS game.
I have a "captain's chair" version of this game. I bought it many years ago - originally working after I got it home - for many years after that as well.
One day, it just decided that it didn't want to boot anymore.
Here's what I've come to find out so far....
Game partly powers up- coin doors light, Power supply puts out power - not getting any sound or video though.
I did test the power supply and it is putting out +5 (5.05 each to be exact) and the 12v is spot on. The CPU board that has the "test" button on it has a LED just below it. I assume that when the boards are powered that this LED should be lit - it is not. "Test" button on board does nothing, reset switch near volume does nothing. Main power fuse is good. I also checked Power Supply Fuses.
Is the CPU board dead? I checked all 6 boards for obvious signs of burnt components and all looks good, traces look good..
Any thoughts?
Thanks,
Muel
