Well, it happened! My Sony 57" RPTV started flickering. DARN IT!!! I called Circuit City and they're sending someone on Monday. Any suggestions of what I should say? Should I demand a replacement set. Will repair suffice? Should I ask him to calibrate the TV while he's there? Do those guys even know how to calibrate a TV? Sorry for all the dumb questions, but I have almost no experience with RPTVs. Thanks.
