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.

SOURCE: volume automatically goes to maximum on TCL TV

The volume (+) button on the TV is stuck or soiled if the volume automatically increases when the TV is turned on. To find out:

1. Turn off the TV.
2. Press and hold the volume (-) button on the TV then turn it on.
3. If the volume doesn't automatically increase, you have a stuck button.
4. If it does increase, you have a faulty key control board.
5. In either case, you have to replace the key control board.

1. Unplug the TV.
2. Let it stand for 15 minutes to allow voltages to drain completely to avoid the risk of electric shock.
3. Remove the screws securing the TV's back cover and pull it off.
4. Disconnect the cable that runs from the main board to the control key board.
5. Turn the TV on using the remote.
   
6. In this manner you can use the remote control to run the TV while waiting for the control key replacement board.

I had the same problem with my tv.No sound! I finally figured it out. It was the speaker wires! Once I changed them to a slightly stronger speaker wire, it worked great! I have sound to my tv and I haven't had any problems since then.

SOURCE: The volume goes up automatically, then after a few

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,
