Is it overheating?

The CRT on the left will need to be replaced. You can test it by removing the CRT drive board from the bottom of that tube and leaving it suspended without unplugging any wires. try plugging it back in and pressing power. If it powers up with that drive board hanging off the bottom of that tube then you know thats the issue and the CRT ( tube) will need replacement. You can get the replacement CRTs ( tubes) from www.tvrepairworld.com

Try resoldering the flyback transformers connections on the board. Its very common for the flyback pins to develope cracks around the pins which can cause that issue. I would check that first with that model.
