So much for fun. Now let's get serious.
In the power supply check R607, Q601, Q602, look for shorted or burnt VDR's, Capacitors, etc.
Check Horizontal Output transistor, Horizontal Driver transformer's solder joints and check electrolytics in horizontal drive circuitry.

If r607 open most likely shorted q601/q602 2sc4834.

Horizontal output area seems fine, Horizontal Driver transformer was fine but i resolder them. I still need to check the ones on heat sinks I Did find on Dynamic Conv. Board was Q1514 had broken solder joint so i resolder it.
