I purchased the extended warranty (5yrs for $300) for my Sony KV-36XBR450 from the Good Guys, who told me that they just started signed a contract with GE for their service & warranty repairs. They said that after 30 days, I could call for their in-home service to do a convergence on my set. Does anyone know if the in-home service is a full calibration? Do the Good Guys/GE techs do a good job? Was it worth the money for the extended warranty?
