eweonardspock that sounds like a bad power supply or a bad disk drive. Unplug your disk drive and see if that noise changes. If it does not, check your power supply. Please remember that capacitors maintain a charge for quite some time, keep your fingers away from your CRT and your caps. For now just do a visible exam. The lights at the CRT could just be coming from some dust and debris on the connections. It does not yet look like that's where the trouble is. After all this baby is a few decades old and has probably seen plenty of stuff. BTW I have two of those and love the retro feel. We need to keep these devices going for another few decades. Do not give up on it....

Just to verify what my colleague @mayer is saying. Take some good picture of just the boards with the caps showing on the PSU. Again, mind them they pack a punch. I am sure you are pretty smart about it, but here is a CRT Safety Guide you do want to read over [document|2759]
