1st Q80R started doing this and after only 2 monthes it lost all power and it had to be replaced. 2nd Q80R tv has failed to turn on atleast 3 times and had to be switched of at the plug and back on to get it working!! £1500 tv? It turns itself back on regularly and has already had a Samsung engineer replace both circuit boards and firmware updateded because they said it was that.. so technically this is our 3rf Q80R and it still wont turn on sometimes without the plug switch reset and it turns on regulary. It has updated firmware on no hdmi device connected... Mega unhappy Samsung customer as the Q80R looks great but the faults are unacceptable!
