I have a Star Wars with a rebuilt K6100 monitor. The spot killer light comes on and stays on. It makes all the game sounds and it does play. However there is only a small straight line on the screen. I know the monitor works because I hooked it up to my tempest game. The voltages on the board test normal except The X and the Y outputs have a negative reading. I did notice when I was testing the Y output The monitor will come on briefly, and the spot killer light shuts off for a quick second,or two when the meter probe touches the 15 V test point, and the Y test point at the same time. It seems to briefly short it out.I also hear the 16 high-pitched beeps when I turn it on in test mode. Not really sure what to do from here. Any help would be greatly appreciated! Thanks

See the manual regarding the tones. Don't hook it to a monitor until you troubleshoot further, as you can risk blowing it, if the board is misbehaving.

I can provide more info later, I'm just tied up at the moment. Perhaps douglasgb or one of the other vector guys can jump in.
 
I always ask the same questions - " do you own an oscilloscope"; "can you probe XOUT and YOUT?". This would be most helpful.

16 tones, I believe implies bad VECTOR ROM? Might just need reseating; if you're lucky.
 
...when the meter probe touches the 15 V test point, and the Y test point at the same time.

If the probe touches these two points at the same time you will send 15v into the Y output which would be "bad".

If the 16 tones are all the same, that means all those tests are passing. But the test do not cover the analog output section. Negative values at the X and Y test points could be bad. If you are measuring DC and it's hovering just under zero, that's inconclusive. Try an AC measurement. Should be around 3 volts.

The easiest first step would be to replace the 40 pin chip on the AVG board. Several people have produced new AVG chips such as this one or this one. The originals are known to fail so sooner or later you'll probably need one anyway.

If that doesn't fix it and all your voltages are good then further probing will be needed.
 
I measured the X and Y test points in AC. Y was fluctuating between two and three. And X was staying steady at three.
