Is my TV haunted?!

I own a Philips 37-in LCD TV that randomly turns itself on, then immediately off again. The screen never displays anything, but the power light blinks on. When it happens, I can hear the click that happens when I purposefully turn the TV on. Occasionally, the ambilight in the back of the TV that provides colored backlighting to reduce eye strain turns on for a second as well. So far, I have not found a logical explanation. If it were IR signals from another apartment or building, wouldn't the TV just turn on? I upgraded the firmware in the hopes that the problem would go away, but it hasn't. It's creepy sitting in a quiet room alone reading and having the TV turn itself on and off. Have any ideas?
