I took the front switch unit to a repair man to have the switches replaced, or the whole cuicuit board. He took one look, sprayed the whole board with WD40, and said try that! When I put it back together, the on/off button worked, but everthing else did not. I then took a can of automotive spray for wet wiring problems and soaked the whole cuicuit board and the switches down and let it soak in. Then dabbed up the excess and put it back together. Everything has worked perfectly now for two weeks!

Re: Keeps changing channels/volume by itself
One or more of the front switches are likely leaky. They are less than $3 apiece and I just change them all to save future problems. You might be able to push all of the buttons on the front of the set a few times such as volume up and down and channel up and down and temporarly cure the problem but the switches will likely need to be changed.
A 6ya expert can help you resolve that issue over the phone in a minute or two.

You may need a different remote. Is this a universal remote? Some of them have these common problems. Mine, for instance, doesn't use the OK button at all; instead, the Menu button counts as the OK button.
Try navigating the menu with the TV's volume / channel buttons (the ones on the TV itself, not on the remote). This usually works. Try that until you get a different remote.
The most common possible cause is the buttons on the set, not the actual plastic buttons but the tiny micro switch (push switch that only should activate when the plastic button touches it)
these go bad and depending on which is bad things happen by themselves.
Lucky that it is not volume up, that is nasty.
The way to prove/disprove this is to get at those--usually they are on a tiny board and if individual ones unsolder the two pins for each (may be more to hold them in place) taking them out of the circuit, set will still work with the remote.
If your troubles are now gone just leave them disconnected and use the remote as only way today to replace is buy that board which will have the same poor quality parts as the old one.
For the tech minded they can be tested with a ohm meter--check resistance with meter set way up to over 20k scale---each has two pins(the switches) and should have ABSOLUTELY no resistance reading unless pressed. I have seen ones reading over 5k or 5,000 ohms and that is enough to act like they are being pressed.
the stations are changing by itself on your TV because the channel button on
the TV is partially stuck in, that is why it keeps changing all by itself.
This same thing may also happen to the remote control of the TV if the channel button of the remote stuck in and pointed at the TV.
Use your finger to rub the buttons on the TV, especially the
volume control button. Do same on the remote and most definitely
problem should be solved.
Please give me a feedback if solution does not work for you.
If it doesnt happen when you change the channel or volume on the tv itself then i would recomend getting a new remote. You could probably get one on ebay. Most manufacture remotes will work on all of their tvs.
Come on, lets try to solve this. Take the batteries out of the remote so it can't interfere and try changing the channels and volume with the buttons on the tv. If this works then someone has spillled something onto the remote and gummed it all out. You simply need to take the remote apart and clean it out. If the buttons on the tv do th same as the remote did then yes, take it back.
Yes. Its probably a stuck button on the TV's front panel. Try pushing or wiggling each button on the panel. It could be the channel up/down buttons or volume up/down, menu, etc.
When there is a button that is making slight contact, it keeps the microprocessor busy attending to the command its erroneously receiving from the offending button and may not allow other functions to work when this occurs.
It doesn't matter which button is stuck, any of the symptoms you describe can happen.
