I looked up the part number on the bottom of the chassis, it's a TS-969 apparently.

A schematic for the board is on page 58

Shure dim bulb it. You should also pull the back & find the horz out transistor.
Then fire it up for a few seconds. Un power & feel the transistor & see if it gets hot. If so dont go further. If cool do again for 10 sec, 30 sec etc. That will get you started.
