So, I bought a 720 that had a "Strange issue" with the monitor. Wells Gardner K5515
The guy said he capped the monitor, but it made it worse.
When I asked about the "Made it worse" he said that the monitor worked, but was really dim.
I pulled the chassis to look for any issues with the cap kit, but it looked fine. All the caps were in there correctly. but the horizontal width coil plug was allmost all the way unscrewed out the top.
So I screwed it back down into the coil a bit, about half way. Plugged in the chassis and fired up the game. it was dark out when I did this and was looking at the chassis when I plugged it in (to check for a spark/smoke).
So I see a red light/glow, then noticed it was the bottom of the Horizontal Width coil. Pulled the plug imediately.... WHAT happened? Can you make a width coil do this if you screw it down too far?
Anyways I am perplexed.... I wonder if it's the coil or something on the board causing the coil to do this.
The monitor did fire up, I could hear it click on, and the HV static. I did not run to see if it had a picture as the width coil was red in about a second.
HELP!
Thanks,
