Go to the back of the unit where you hook up the cable. You will see a thumb swith labeled "center channel audio". Flip it to the OFF position and you should be OK. Turn down the volume first so as not to blow the speakers. Let me know if I can be of further assistance

Blinking light without picture on Toshiba 57H81


No good news here sorry!

Power board and video X and Y boards need intervention If you are going to take a look you will find that one or even both boards have blown capacitors and burn marks along the transitor

You might be able to claim it as fusion on your insurance policy ( parts only usually) but thyat at least is some relief

Toshiba Regza 32C3000A tv sound keeps droping out, the mute button when pressed on and then off brings it back on. seems as if the tv is auto muting itself?


Could be a contact piece of the MUTE button from your remote that is causing it.
Go out and Big Lots or Radio Shack to get a cheap universal remote control(big lots would be between $5-$10) Pick up the code for it,and when the tv happens again,your the OLD remote MUTE button to turn it back on and then put away this remote control and use the new universal remote control.
However,if the problem is coming from the manual MUTE button on the TV,you need a repair tech, to fix it!

Check all fuses in the power supply and look for any bad connrctions on the PCB. You are probably missing the 130 volt supply to the horizontal circuit. Common reasons are: Shorted horiz output transistor; flyback transformer, picture tube arcing , bad power regulator IC. In short, you need to get a qualified tech for this symptom. Hope this helps.
