Question from Terry: I bought a Street Fighter II arcade with a Wells-Gardner 25K7181 monitor. The upper left corner of the monitor has a blue cast. It covers about 20% of the screen.

In the screen test mode to white lines in this area are blurred and you can see the red, green and blue lines almost line up to made a single white line, but they are off a little causing the miss color. The prior owner said it was like this the whole 3 years he owned it. (He bought it from a private owner, didn’t have key or know how to open the cab.)

I thought it might be a degaussing issue when I bought it but no luck with the degaussing coil.

Does that sound like a tube issue or a chassis issue to you? If a chassis issue what is you charge to repair it if I send in the chassis.

BTW I own several games and love playing them, but I’ve done minimal work on them. I’ve never discharged a monitor or removed a chassis, but I think I can do it after watching your videos. However, I would probably screw up installing a cap kit, because my soldering skill is poor.
