I left my TV on with the screen saver on when I left home for about 25 days, when I cam home the picture and sound are gone. I can see the red power light turn off when I power on and I can see power go tothe external hard drive with movies. Inside is a small green led light blicking slowly, I took the cover off and all looks in order, The TV is too big to take to the repair and they donot pickup, and I have no one for help to move it. Maybe I can take it to them board by board, and let them test each one till they find the bad board? Any ideas what to look for on the board for indications. It responds to the remote control, I can see the red light come on with each press of the remote. I tried the TV own manual buttons, no success
