Nope I thought about that too. First of all, it does it even when using the power button on the unit. Also, I tried 3 different remotes and it did it with all of them (and one of them did not repeat the signal like most remotes do). I also tried holding the button for different lengths of time and that too made no difference. I guess it may be a design flaw (something that seems to be quite common in Panasonic's current products). :|
