After 5 weeks my Panasonic TH42PX80B has failed. I was watching it when suddenly the screen went blank and the red standby LED flashed seven times. I unplugged the set, left it for ten minutes and tried again. All I am getting is the LED blinking seven times, there is a pause and it blinks 7 times again. I would appreciate any advice as to what might be the problem. Bought the set from Richer Sounds with at home warranty. Will insist that they replace rather than repair the unit as it surely shouldn't fail after 5 weeks.
