Toei A20H Chassis - Changed voltage regulator and hot - occasional screen wiggle-dim

OK.. I'm working on this Toei Monitor. A20H. I get this voltage drop once in a while. Then the monitor is fine and plays for hours. No issues. I changed the voltage regulator and hot and the same thing occurs! What would cause the voltage drop/wiggle and then it will never do it after freaking out minimally. Any ideas? Anyone run across this?
 
It's the largest one - I don't know the location or value on this monitor though.

Incoming AC line voltage is rectified, then filtered by that capacitor - and then it's regulated. But if the capacitor is weak, you'll get noise in the power, and the regulator won't be able to stabilize it.
