Looks like some of the Electrolytic Capacitors in the Vertical Output stages have dried out and need to be replaced. If you are conversant with Solid State electronics servicing, then you can make an attempt. I generally do not waste time identifying the faulty capacitor, but replace the entire lot in thre Vertical stages. There are not more than 8-10 of them. Since you are changing them en masse, should not take you more than 30 - 45 mins to desolder the suspect ones, and solder the new ones. And it also saves you the bother of new problems cropping up in the near future, as all potential problems with old capacitors get removed.

Do the reset test.I give this 50/50 chance of clearing it up. Disconnect the power cord for 4 hours. Then when you power it back up the internal soft codes will automatically reset to factory defaults.
