Hi Everybody. I had my new PV500 delivered on saturday and have just checked the hours running time in the service menu and it is showing 102! I know that that we have only had the screen on for about 15-20 hours max. Surely a new screen would not have 70 hours running time already. Spoke to the retailer today anyway because I had noticed marks on the top of screen surround and he advised that I should remove protective film but I have checked and cannot see any film attached!
