    Thanks everyone for your help! I will show these solutions to my son and see if he can resolve; if not, we may just have to get a new set. (I don't really want to....I really love this TV). Where is the best place to get parts? I have been reading that there are a lot of defective parts direct from Toshiba. (mostly bulbs)

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:

I have the same issue with my toshiba 32" circa 2000. I am told that it is a burned out diode of some sort and it is a horrendous repair job.

SOURCE: Toshiba model 61h71 red light comes on /no picture or sound

We had the same problem, open the panel on the back of the tv, the board on the left, not the one with the convergence chips. Inside the tv u will see a piece of paper with the fuse info. The board on the left unscrew it and flip it away from you, the fuses to test are at the bottom, on the circuit board it will say 125volt 5 amp, and the number starts with an f. they are small and rectangular and black. Check all but the 3 at the bottom are usually the culprits Hope this helps u

SOURCE: No picture, sound and flashing red power light...

Pull off the back pressboard. At the bottom left hand corner is the power cord that attaches to the power supply board. There is a white plug that attaches directly to the power cord. With the TV power off, pull this white plug up to disconnect. Then push it back in. Then plug your TV back in and press the power button on the front of the TV. I just did this and it is working fine.

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.
