Second >most likely would be a video output transistor, I'd guess. Another strong possibility is a bad solder joint for the red drive connection to the small pcb mounted at the rear of the CRT. It should be labelled "r" or "red". For some reason there's a high failure rate for solder joints on this pcb, possibly caused by vibration of the CRT. I fixed a color TV that I scrounged from the neighbor's trash by locating and resoldering two bad solder joints on this pcb, one of which was the red drive.
