Volume go up to MAX, power button does not work

I have a Toshiba model 32A43, the other day, without any buttons being pushed, the volume suddenly went to maximum, the power button would not work, volume can not be turned down on the set or by remote, but the channels will change using the set's controls. After turning the power off at the power strip several times it finally seemed to reset. It worked fine for about a week and did it again. The buttons don't seem to have the same "feel" as when it was working properly. Can it be fixed? If so, about what should it cost to fix it? Should I toss it and get a new one?

    My volume does just the opposite! Automatically decreases to -0- and after a while will respond again for a short time. The controls freeze up the same way. Just a guess but could it be a inferred receiver problem within the TV?

To all of you, change the tact switches (all of them) on the front panel control board and end of problem, very common problem, part number for these switches is 23344443, any or several will become "leaky" and give all sorts of symptoms, MANY times this is caused by using windex or similiar type cleaners, it gets into the switches and corrupts them, this will fix-ya, BMW Rider

Toshiba tv 32a43 changes input by itself


I will try to explain this: I first presume there is a physical button on the set for the input options.

I have seen this a lot:
Not the plastic button on the set but the tiny push switch behind it.
These are called momentary switches as only should function when the plastic button is pressed and contacts the momentary switch.

They go bad, and will internally engage without be touched.

The simple way to prove/disprove this is to open the set and get at that switch which usually is soldered into a small circuit board--two pins for the switch and maybe two more tabs for mounting.

If individual switches unsolder and REMOVE THE INPUT SWITCH (the one under the plastic button on the set)

Set should now operate normally and remote should have same feature on it. If it works you do not have to replace anything.

FYI: the reason the remote may not be working is the buttons on the set have PRIORITY over the remote.

Both the remote and the buttons go to the same area inside the set but buttons are #1 in line.

When we try to turn on the tv (toshiba model 32A43) it makes the sound of turning on then off and the screen stays black and a red light by the power button keeps binking


You're either losing high voltage or power supply is not producing the horizontal drive signal, Check for 130v on the collector of the horizontal output transistor, if you're missing your voltage, you have a power supply problem. If voltage is too high you have something open in the power supply such as a low value resistor. If its low, something is shorted in power supply, possibly voltage regulator ic.

Model: 32A43 Problem: Volume goes UP automatically. Channel scolls automatically. I tried using the remote and the buttons on the tv panel but neither works. I tried turning the TV off with the remote and...


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.

Hi, You can try resetting the TV. In some other brands/models, hard reset is done by unplugging the TV from the mains for a couple of hours. Preferably check your owner's manual for more specific instructions. Good luck and kind regards.

Toshiba TV 35A44 Volume Issue


I had the same problem, you'll probably find that that particular button will push further into the set then the others, this is due to the a weakening of a cheesy metal guide which directs the projection off the back of the button into the corresponding microswitch. This metal guide will bend and will push against the switch.My solution, (and it ain't pretty) was to unplug the set, remove the button( I used a dremel cutting bit), locate the guide,a small metal plate with a hole in it. Bend the plate toward the front of the set then tape over the hole. I haven't had the problem since.You WILL have to use your remote for further functionality of the volume, However all of the buttons seem to be inherantly poorly designed and will weaken over time, AVOID USING THEM!

Menu won't stop popping up!


The first thing I would check is if any of the buttons on the tv has been push in too far including the menu button,if any of this buttons is making contact it will confuse the microcomputer and the rest of button become inoperable.Another possibility is corrosion in the buttons beacuse soemething has spill into them like pop or water.Check it out and let us know.Be careful,make sure set is not plug in.
