That relay is supposed to engage power to the tv boards that control the screen.
you will have to take it to a oualified service center , because they have access to parts that are needed for repair

Toshiba Model 57H83 Rear Projection TV Lost Picture and Sound


the most common problem in this set is convergence---two chips are used and if one shorts what you have happens--only way to prove this is get at and unsolder all 18 pins on both chips----if set turns on then the chips and or a resistor near them are bad.

Soldering and getting at the chips requires some skill--the parts involved usually are under 30 dollars total.

set uses chips like these:

Toshiba 57H83 and no longer get any sound. Any


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.

Screen turn green tv is 57 rear projection


Good Day,
It appears that you may have a green drive issue. Try adjusting the Sreen Control it is located in the front of TV.
1) Remove Speaker Grill (it just pulls off) start at one end, 2) Remove cover (5-6 screws), 3) Adjust control. The control is located on lower right side towards bottom. A small black device with 2 rolls of controls, adjust the center control on bottom row counter clock wise, until you get a black and white picture.(adjust with color control to min).
If this does not work you light bulb (CRT) is bad about a $750.00 repair.

Good Luck, Big Irish.

I have had a shorted picture tube do that on a Toshiba before. It could also be a Flyback transformer arcing.
You should call a good TV Tech for an estimate.
