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.

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,

SOURCE: volume turns to zero constantly
Sounds like your volume down button is jammed in on the set, you may need to take it to a repair shop if you can't free it up from the outside.
