It sounds like the switches are bad if the plastic buttons are not jammed. But there is also a problem caused by these new low energy lamps that people are using to illuminate their rooms. They can emit a similar frequency that floods the remote sensor and sometimes the microprocessor reads these frequencies as functions. Turn off the lights or cover the window on the TV.
