There is a damaged [leaky] transistor at the electronic volume control section circuit. Contact any service technician. To locate the exact one, is a skilled work. Even though the cost of component will be too less, the service personal will have to strain to locate it, and he/she will charge for it. http://google.com/+GopakumarGopalan

SOURCE: Volume

It's rare but happens. Sometimes the volume button (or rather the plastic piece that activates the button when pressed) can get stuck. That or there has been a cleaning chemical leak down onto the button on the board itself and corroded it, causing a constant short.

As for the second Q, I feel that your TV may have received a shock through the audio line and the audio amplifier may have taken the hit. These problem can lead into multiple bad compontnts, such as a bad SMD IC on the bottom of the board.

SOURCE: Model: 32A43 Problem: Volume goes UP

check the front button plate on the front of the tv very carefully.if it has been hit with something and either or any button is pushed in,it will not listen to other commands.make sure each button has a distinct click when pushed.a frozen button will cause other things not to work.it sounds to me like two buttons are making contact,and they are beside each other,so the button plate is crooked or warped.

SOURCE: Volume decreasing to zero by itself

Have you looked to see if the Button on the tv itself is stuck in. Press it and you might be able to feel for it sticking. If this is the case you may want to try a baby wipe or something similar to try and sort this out. (dont use a sopping wet cloth)

hope you get this sorted.

SOURCE: Toshiba 32A33. Tv Goes into menu

Hello
Just check whether the front panel control buttons are jammed or not first. The fault you reports indicates taht. If there is no such situation, the microswitches inside it is damaged. Microswitches and one that gets in contact with the pushbutton switches you press at the front of the TV panel. These are fitted inside the front panel control. There are six of them inside your Tv. All of the are alike, and replace all the six of them at an instance. Thery are cheap to buy, and can be purchased from any electronic sparepart shops near your area. Open your TV and locate the switches, usually fitted on the front panel. Resolder it one for sample, and go for the new one.
OK.

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!
