Panasonic PT-47X54 47 in. HDTV-Ready CRT TV

Great picture at a great price. BUT two service calls in the 1st 2 1/2 years. One was after three months some transistors blew. Then the service rep requested a schematic from Panasonic and when he got it, the circuit in question had been left out of the schematics which meant another two weeks of time. Then 2 years later the red convergence went out. Panasonic offered to refer me to a tech which I would pay for because the factory warranty is only one year. Costco policy has changed and only cover TVs for 90 days now. I called Costco service and am waiting for a funding approval which they claim most likely will not happen for the @ $400 repair cost. I could fix it myself for under $100 but don't know how. The manager says he will have his guys take a look at it and see what they can do. I think that for $1000 a TV should last longer than 3 years.
