When I use my Vizio tv remote , the screen of the P5 turns off . Plus , if I use the tv remote many times in a short period of time , the P5 just turns off completely . I must turn it on with the switch of the rear panel .
sorry for my poor English
Sorry , I put it in the wrong section . Is it possible to post it in the power section ?
Moved! 
My guess is the TV remote uses some of the same codes as the P5. If you do not use the P5 remote, you could cover the IR receiver on the P5.
