Just moved my donkey kong into my new arcade and fired it up and the monitor is doing the following, see pic. It has had a cap kit in the last two years, Sanyo EZ20, Any ideas?
Normally, I might say degauss it, but this looks to be something else. Agree with Buffett, check the B+ and verify cap kit was fully done. If you have a degausser, hit it just to be sure.
