I have a Toshiba theaterview the sound don't work

maybe your video cable is bad

I don't think that cord will work. HDMI carries video and audio signals, you might get video but probably no sound. You might as well try anyway though so here goes... The red green and blue plugs are your video and the other red plug and the white plug is for stereo sound. The yellow plug is just a lower quality video plug. So plug in the red blue and green plugs into the component video inputs on the TV then the red and white plugs into the audio inputs. DON'T plug in the yellow plug. If this doesn't work go to your local home theater store and ask for a receiver or switcher that will downscale high def HDMI to component video and stereo audio. You can probably pick up a cheap one for around $100. Good luck!

Theaterview suggests a rear projection--in that case it most likely is in the convergence circuit--unsolder chips (convergence) and see if set turns on.

Some of their regular TV sets (picture tube) if the light is just blinking means the same thing=shutdown because of a short/problem but a model number would tell me which you have.

A model number is needed to assist you but a general answer is:

Likely damage is in power or standby power supply the set uses.

A visual look in that area might tell you what is bad---follow power cord inside to the power board where it goes directly.

You may have overloaded your audio output with the external speakers(impedance or short wire problem?)as a result the audio out i.c maybe damaged which in turn may have blown one of several fuses in the power supply.maybe regular GMA type fuse or picofuses,you can try replacing blown fuse but if they blow right back you`ll need the help of a repairman

On my toshiba I just use the input button on remote.

sound like to me caption 1 is turn on .. try going into settings menu and shutting off close caption...

yes its on your remote. its the c.capt button. or go under menu/enter and pan to the left untill it comes up. and turn it off by scrolling through the caption buttons

What is the model number?
