that relay is supposed to engage power to the tv boards that control the screen.

I had the 65" version of that TV. Loved it, unfortunately it went bad as well. It sounds like the red tube went bad. The tube itself might sell for $400 plus. The installation will take several hours with the alignments which will need to be done. Then after all that you will start to have to worry about the other tubes starting to deteriorate. If there is any red in the picture then the tube is most likely the problem. At tat point I would say buy a new TV. The best bang for the buck if you want size and have the space for it would be the new Samsung or Mitsubishi DLP's. I just installed one at customers house. The 60" Mitsubishi is 1400 at Best Buy Good Luck Rob

Maybe I can help. This symptom is caused by so many different failures inside the set. Most commonly, convergence chips go bad. Next, capacitors get weak in the power and sub power supplies. And finally, the hyper module eventually needs to be rebuilt by replacing all low value surface mount capacitors. All of these repairs will be needed on your set. All of these repairs require test equip and soldering / desoldering equip. In most cases you can have the set repaired for 200-350 and expect the high end of that range. If you attempt repairing it yourself, you can usually check for open pico fuses on the board, then disconnect the convergence yokes to see if set comes up temporairily. The best I can do is to inform you of your options and what to expect. Overall, it is a good, long lasting set and if it is repaired properly the first time, you should get at least ten more years from it. Well worth it in comparison to a new set that commonly requires an extended service plan just to get through the first five years. Good luck, Russmann.

Testimonial: "thank for the help it was fast "
Most often No Sound with Toshiba 57H83 is:
1. TV has a Sound on-off switch on the input panel at the rear of the TV. Very hard to see, black on black. Used to turn off speakers if you use a separate or external sound system for speakers. Usually gets moved while connecting hd cables or dusting and vacuuming in cramped space at the rear of the TV.
2. Someone accidentally changed Sound settings with remote to CC (closed caption) or SAP. Turn off in sound menu and save preference.
3. Sound input plugs from external cable or sat box unhooked or wrong input.
Toshiba 57H83 no sound fault is not common. If you still have no sound, get local service.
Or troubleshoot yourself to determine if Tuner, IF, processing, sound demod, switching or sound output circuit is smoked. Then make an installation plan.
