Funny that you expect everybody to know what a "2900-5206" is.

I suppose you know that, between vacuum-sealed CRTs and high-voltage
power supplies, there are numerous hazards in working on a monitor.
Some of the hazards are tricky. You would be wise to get help from
somebody who has experience doing this type of work.

But a commonly cited source of advice seems to be the following:

"Notes on the Troubleshooting and Repair of Computer and Video Monitors"

I have not tried the described procedures myself, so I can't give much
more help than that. But be careful.

Well, I'm the guy that needs to fix it, so i turned to myself, and
switched out the board from a 2900-5201-7100, and swapped ICs out.
Everything worked fine after that. Thanks anyways.
