I just got one and the volume automatically goes down when i use the remote it fights to go down as i push the up button, than when i use the tv volume button, it will stay for a few seconds than the volume will go down.

Hello,
it would appear Volume down button is either shorted or something is constantly pushing on it forcing the volume to go down. You could try to press on the down button and see if it feels like it pushes back a little bit. The most common thing is that it gets sticky from grimy, sticky fingers, try to un-stick it using some alcohol on a cotton swab. Other that the only way to fix this is to take the tv apart and figure out the button problem that way!
Good Luck!

Chances are that one of the volume buttons (either on the TV itself or on the remote) is stuck. You'll be able to know if it's the remote by taking out its batteries and trying the same process. If the issue persists, see if the volume down button on the TV is stuck and can be freed.

The digital main board has the fault. This is not a user repairable one. Contact any technician.

Most of the time it is the touch button assembly on the tv. The Volume down touch button switch is sticking.
I hope this helps,

Try this, using the Panasonic remote, wait until the notice about your lamp goes AWAY (it wont work with the message still up).
Hold the volume down on your tv while holding the split/play button on the remote.
You will get a notice about 4-5 seconds later that it was reset.

I am having same problem on 32 inch same problem. After playing with board with no results,I tried front buttons and found that if I held the power button in ever so slighItly as not to turn it off, it fixed problem which is the micro on/off switch, I removed the switch and used the remote and everything is back to normal, I am about to insall a used micro switch after I finish typing this but I am sure this will clear up volume problen and menu going crazy problem if not I will just leave micro switch out and use the remote, and I will get back to this board only if that micro switch still causes the problem, so if I don't post in next hour the problem is fixed and I'm more than glad to help.

well depends on how far it turns the volume down as to what the cause is and if the volume bar on screen display comes on when the vol. goes down. if it just goes down a little you probably have the "smart sound" setting turned on in the audio menu turn it off and see if prob. goes away. if the vol. bar comes on the screen whenever the vol. goes down the you most likely have a bad button on your front panel and it doesn't have to be the vol. down button. it you think it is the button it would need solder work to be changed most likely shop job.

There's a setting in the menu. I think it's called "smart audio". It's supposed to adjust the volume automatically for commercials. But I don't think it works that well. Give that a try.

the channel down button is stuck on, you need to replace this switch internaly to the set.

help the volume on my tv keeps going up and no one is touching it! please help. my parents cannot afford a new tv
