If you read through the other threads mentioned above, that will give you ideas of parts that frequently require replacement in this set. Check the controls, too, a dirty brightness or contrast pot can make troubleshooting interesting... and the more aging parts you replace, the more reliable the set will be in use, hopefully.

That's what I was just thinking, probably bad electrolytics and paper caps and some bad resistors as well, which should be pretty easy to replace in this set since it has PCBs instead of actual metal chassises to work with, I also noticed that in one of the bottom vent holes I saw a pretty large selenium rectifier that could also be causing some issues...
