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.

Hi, common issue with rca sets, you need to replace the tact switches on the front control board. If your not good at soldering / un-soldering you may be able to still purchase the whole control board, call a local tv shop with the complete model # and chassis # of your set and they can give you price & availability, video-tek
