I agree that this is the most likely cause. I'll add that this can 
sometimes be reduced a bit by changing the "economy" or "green" mode of 
the TV, turning it on or off. This changes the frequency of the 
backlight, and can prevent the receiver from thinking there is an IR 
signal when there isn't.

I'll also disagree with the assessment that it doesn't harm anything. in 
the case of my Sony TV, if it's in power save mode, I can hardly use my 
IR remote without it missing every third or fourth keypress. YMMV, I guess.
