I have a Toshiba 32A33 32", and it seems like it's taking its own decisions. The buttons on the front panel don't work and I stopped using it 'cause sometimes sound goes louder and louder, and it changes the channel by itself... until I unplug it. Is there anything I could replace? My brother is a technician and I could tell him to replace or fix any part for me.
Cardpsycho is right. We had the same problem, among many others (unresponsive remote, none of the buttons on the set working at all). I taped a penny very firmly over the tv/video button on the set to keep it depressed at all times. This fixed everything!!!
Just a quick fix that might work wedge something between the video button on your tv to where it is pushed in all the way then your tv shouldnt have a mind of its own anymore and the romote will work again . Just saying this cause had the same problem and thats what I did and my tv work fine again

The problem is most likely the switches on the front panel. If the manual buttons are constantly shorting out, then the TV will try to respond to those buttons, and not the remote. Manual buttons almost always override a remote. Check the front panel for shorts, or if the buttons are constantly depressed.
The problem is most likely a short in the switch panel on the front of the TV. The remote won't work because the TV thinks that you are using the manual buttons on the front, and the manual buttons override the remote. Have the front button panel replaced....it's under $200.00 - or you could solder the switches apart and just use the remote.
Is the favorite channel menu a function that is normally accessed by a button on the remote?
If so, that button on the remote might be stuck.
If this is the case, the menu may at times pop up all by itself and other buttons on the remote and on the TV's front panel may not respond at all (it had happened on my remotes more than once).
Try to clean the remote control (the housing, rubber pad with knobs, circuit board) with ethyl alcohol, when you clean the housing, you should also clean the holes through which the buttons protrude, there might be some dirt that keeps the button stuck.
It may also be a stuck button on the TV front panel, so check these too.
Also, it could be something else, i just wrote the description of a problem and the solution which to me seemed most likely.
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.
I had the same problem on my 61" RCA TV... The switch for the power/channel changing buttons seems to be a faulty product... However if you are a little technical you can open up the front of the TV and disconnect the button panel from the tv and just use the remote to operate it.
It looks like one of the buttons on the front panel is stuck, base on the info you have provided; the volumen down button is stuck. The remote or any other buttons will not be operative until the fault has been remove.
I would suggest to try to press the Vol. down a few times just to see of it unlocks, if that does not work, the front panel assembly will have to be remove and try again if it works with the remote or manually.
The last thing to do if none of the above works, it will be to put a new switch.
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!
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
