Long shot but here goes. I have had this HD LCD for about a year. (used from my uncle who bought new in 07 or 08 he upgraded to a 3d) Anyway... at any given time the tv will turn on by itself or turn off by itself and display the "latest firmware update screen" You cannot navigate to anything else. I have tried to reinstall the firmware from the philips website and when I insert the usb stick with the autorun.upg the tv will not take it. (it will not recognize the file. I have made sure it is in the root dirctory, etc.)If you unplug the tv and let it sit for a while it work again but who knows for how long before it shows the same firmware update screen. Philips is no help at all. I hope I didn't break any rules for posting here. Here is a pic of the screen I get. It doesn't make for a happening Saturday night Any ideas?
