I have a Panasonic TH-46PZ80U that is barely 2 years old. Worked fine until 8-6-11 when it failed to power up and started blinking a series of 10 red lights. Called Panasonic, they gave me number for local TV repair. Local TYv repair shop wants $100.00 to show up and diagnose, with no word if Panasonic will cover the c ost of repair. Any ideas? Thanks, Dave
