There are Mylar capacitors that go to the base of the regulators. I have found some to have decreased in value or be leaky. Second is a VDR that goes to the standby transformer and may or may not have a low value resistor in series with VDR - replace both as they supply the voltage ( 12-15 VDC ) for the regulator circuit to work. Be sure the Driver Transformer for the Horiz Out transistor has been resoldered. Foremost of all , for that size of set - original real McCoys from Sony will hold up ; others simply will not from bitter experience. If that was the ONLY problem ; put a MOV 150 VAC and biggest disc one you can find across the AC Line AFTER the fuse ; this protects your job. I did not do that on one I had and it came back and I put it in then and it did not come back. Never mind the fact it already has one - put one of your own in unless you don't mind doing it over and over again ! Best: Eugene
