Buttons on front unresponsive

All buttons on my TV are unresponsive - power can only be turned off by unplugging, volume goes to max and channels go from highest to lowest or vice-versa automatically.

Re: buttons on front unresponsive

Front control board needs to be replaced or eprom is corrupted one or the other, would have to do a couple of checks to know for sure, a tv tech can tell you 20 minutes after he gets there, neither part is a big bucks repair, hope this helps, BMW Rider

Tv volume stuck on max, volume + signal stuck, button is fine.

The problem is on the board with the controls----if remote receiver is not on same board disconnect that board--if it is unsolder the vol and channel buttons--the front buttons have priority over the remote--buttons will look fine but the switch under each will be your problem---better hope it is as only other cause is a microprocessor gone mad.

If you have a Ohm meter I can tell you how to prove this--going to have to get at the buttons--if you want to prove it is or is not a issue with the micro switches you are going to have to unsolder or test them.

Channel 3 is probably locked out... here is how to fix it....

2) Scroll to highlight INSTALL using down arrow on the remote or Channel - on the front of the TV.

3) Press the Right Arrow on the remote or Volume + on the front of the TV to access the INSTALL menu.

4) Scroll to highlight Channel Edit using down arrow on the remote or Channel - on the front of the TV.

5) Press the Right Arrow on the remote or Volume + on the front of the TV to access the Channel Edit menu.

6) Use the Left or Right Arrow on the remote or Volume + / - on the front of the TV until you get to Channel 3.

7) Use the Down Arrow on the remote or Channel - button on the front of the TV to select SKIPPED.

8) Press the Right Arrow on the remote or Volume + on the front of the TV to select OFF.

9) When finished press Exit on the remote or press the power button on the TV and then power the TV back on.

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 sounds to me like two buttons are making contact,and they are beside each other,so the button plate is crooked or warped.

How to unlock my jensen tv

the tv should have buttons to change the input also. Or just hit channel up on the tv, that should do the same. That should do the trick if it is on the wrong input/channel. You could also try unplugging the tv for a minute. My tv goes back to channel 3 when unplugged.

Volume stuck maxed out

the intrenal switch that controls the volume up is shorted. you need to have it replaced. the short of the switch doesn't allow any other buttons on the set to work because the micro is recieving the volume up command. it's as if there is an invisible finger pushing the volume up button. the switch is a tachtile switch which is very inexpencive to repair about $50.00 total. if you want to do the repair yourself be aware there are voltages that remain in the set that can be harmful. 50% of the time the cause of these switches shorting is improper screen cleaning. some people spray glass cleaner directly on the screen, this is bad. the cleaner drips into the set and lands on the PC board where the buttons are housed. but I've seen the other 50% also which is hummidity, dust(not anyones fault this just happens), and simple switch failure. so becareful repairing it your self
