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.

As stated by TVtechlady, it is possible for the buttons to be stuck. With the set unplugged, try pushing each of the buttons one at a time. You should be able to feel the button engage. If one of them does not, then that is the likely bad one. Also, if there is some dirt caught between the button and the hole, it can create enough friction to prevent the button from returning to the "OFF" position on its own. Spray some compresed air around the buttons and work them a few times by hand. Plug hte set back in and try again,
It is also possible that the 5V supply inside the set is having a problem and is comfusing the set. Try working the buttons first and update this with the results.
