More and more frequently, when I turn on my tv (Philips LCD TV - 42PFL3704D/F7), it will freeze on the Philips logo screen. The only way to turn it off is by pulling the plug. Leaving it unplugged for a couple hours has always remedy the problem the few times its don it, but this time, it doesn't seem to be working. I looked through Philips help section but they didn't have anything. So I emailed their support team, who's only response was to look in the help section. Does anyone know why my tv is doing this and more importantly, how to fix it??
