Ok, I just got finished installing the cap kit for my WG K7193. Powered it up and I still have a slight wave.....looks like it is only in the corners, mostly the top!
I changed a couple of the output capacitors in my game's power supply (they were the only ones I had laying around). And it didn't help! I will have to get another power supply and test it.
I noticed the horizontal position pot on the remote is cracked and it doesn't function. When I turn it there is no movement on the screen until it hits the end and then the screen jumps to one side and then back to center when I turn the pot back. Could this be screwing up the screen? Because sometimes when I touch the remote pad the screen goes hay wire until I tap on the remote board. I just noticed this today..........any thoughts on this? Probably the cause of the whole damn problem!
Thanks for any advice/iput/suggestions/criticism..........

Tried a different power supply tonight.....no difference! Still have the wave. I also tried moving the isolation transformer further away from the tube. No change. I even added a line filter with no effect.
When I power up the monitor the wave is VERY noticeable. But after a few seconds it fades into the usual wave.
I am lost........anyone? Anyone?!
Thanks,
Jim

Do you have a frame ground attached to your monitor from the game power supply?

A broken pot can cause problems. Bob Roberts sells a whole kit of the pots for this board. It's on his parts page under Resistors.

I have the ground from the frame of the monitor going to the green wire on the 3 prong outlet. Should I tie it to the FG (earth ground) on my games power supply?
Ken, yep, next trick.....install pots from Bob!
