Causes

 * Capacitors on gain board are failing

Solutions

 * Replace C569 & C215 capacitors

Disassembly Notes
It's a CRT which should be discharged before working on it.

There are screws on top of the case under plastic caps.

The plastic is fairly brittle now and when rotating the case you should think through how the weight will be put on parts as you remove them and be careful. You will mostly likely damage the caps on the top screws removing them
