    The volume has started to go up and down and often times goes all the way up to max. Additionally the channels are changing constantly and I can't stop it. Piece of crap!

    hi i have a 36a43volume wnet up and down radomly as well as the channels and all off a sudden quit alltogether.... ne idea where to get a schematic?

    We have exactly the same problem. The volume suddenly goes to 0 (minimum) or to 100 (maximum). We've only had the TV for 4 years. I don't know if it's worth it to fix it or buy a new TV?

    I have a 32A33 with the exact same problem as last guest. It was going on for a while but could control it somewhat. Now the volume goes down then all the way to 100. Have to pull the plug now to shut down. Can't watch it anymore cause now it's a continuous problem. Have a brother in electronics who sells capacitors. Will have him check it out and let you all know. Still shouldn't happen. Things are not made to last anymore. Will probably not be worth taking it to repair shop.

    I am having the same exact problem with my Toshiba 36A43 36' TV. The volume goes from 0 to 100 and back again continuiously, the channels never stop changing and the only way to turn it on or off is by the electrical cord. I contacted Toshibia and they claim its not their problem. They said the tv worked fine when it left their factory and that there have not been any recalls.

    I have this model TV. I just had it repaired because the picture was very dark, and it cost me $130.00 for the house call and adjustment. Just yesterday the volume increaset to 100% and I lost control of the TV. I couldn't even shut it off, I had to unplug it. After a while the problem went away but it keeps coming back.

I had the same problem with my 36A43 also. I found by pure accident that if I pushed and held the MENU button on the front of the TV that the volume quit going up and down and I could control the volume with the remote. So far it is working all I did was jam 2 or 3 tooth-picks in beside the MENU button to hold it in and it is working so if this helps you any good luck its a cheap fix for an old TV

    I would like to jam the whole TV up Toshiba's rear service center entrance. This is ridiculous, I paid a premium price for this large TV and have hardly used it over a 5 year period. Have had numerous issues where the sound goes wide open and makes it unusable. Then a few days later it may work fine but you never know when it will strike. At times it refuses to come on at all and right now is one of those times after I had to shut it down a few hours back because of sound. Toshiba should have made Barney Fifes first TV so it would go with his first car!!.

Yes, please check with your brother and let us know what would be a good solution. Has anyone else had their problem fixed? I just called Toshiba and they were very unapologetic about the poor quality of their product and just referred me to a service center.

This problem sometime occurs due to a bad capacitor in the volume control circuitry. You will need a multimeter and a schematic to find out the proper voltages within the volume control circuitry. I would suggest that if you do not have a background in electronics that you take the set to a qualified shop for repairs.

Thank you,

Toshiba 36a43 i have picture but no sound. Volume control works but again still no sound.


Things to check:

In menu are speakers (audio area) switched on or off?

If you put sound all the way up and listen right at speaker what if anything do you hear?

If using a cable or sat box is sound turned down on it?

Is sound muted on set or the box (if used)

Do you have sound with a DVD etc hooked via the rear jacks?

A few sets have a slide switch on the rear= internal or external speakers--is it set to internal?

failing all of the above you have a audio circuit problem

Toshiba model 36a43 The tv stopped responding to remote, bought univ remote does not work, but works with other tv. The menu buttons are inconsistant the volume goes up OR down when pushed, the channel...


What you're describing sounds to me like "Windex syndrome". People sometimes clean the front of their TV by spraying it with glass cleaner like it's a window (which it basically is) and wiping it off. Unfortunately the cleaner can run down onto the circuit board where it damages the switches and wiring. This might be what's happening in your TV, although the same trouble can be caused by other things as well.

The way the front panel controls are wired, a bad switch can cause all of them to act up. The remote sensor is part of the chain too, and if it goes bad odd things can happen. If the set is in an area of high humidity the same trouble can develop because of moisture. One of the switches might not be operating correctly, or another part in the button chain may have gone bad. The microcomputer in the TV may be bad. If you've had a recent severe thunderstorm with nearby lightning, this may have affected the chip.

Try unplugging the TV from the AC outlet, not just turning it off. Let it sit for 5 minutes to make sure that capacitors have had a chance to discharge. Press a couple of the front panel buttons before plugging the set back in. Then plug the TV back in and see if you still have the same trouble. This process makes sure the microcomputer inside is fully reset and often gets the set going again.

If the trouble continues, someone will need to check the front panel switches and the circuit board. That's the area where the cause will be found.
