I hope you are not either Jeremy. 3 power supplies in 2 years on an 09 50" Panny. Won't turn on, 7 blinks of death. Maybe your TV ddi not like the order, or how fast you shut other inputs down.
Our 2009 TH50PZ 800U is toast .. Love the picture and the sound , but the power supply boards have the lifetime of a nickel rocket. It was one notch down from the top in 2009 with THX. Thankfully bought a warranty; 3 power supplies shot in 2 years. Dealer will replace it after...
