A prime suspect for frame collapse is the reservoir capacitor for the frame output flyback supply, possibly 1000uF/40V or similar and which might be that orange ROE cap visible near the edge of the board in the pic. Even 25 years ago they were failing so regularly that I used to change them on sight, working or not. I can't recall if it takes out a fusible resistor with it. The frame output IC and other stuff did fail too but that was the most common cause.
