Query: Sony Projection TV

Sony 57" model: KP-57WS500Very poor quality; Started having problems after 1 year. After 1-1/2 year, the technician came out and charged me $200 to adjust two screws and tell me all the CRT tubes (guns) were going out. I can't even find reference to a warranty in the owner's manual. I tried the Sony web site, and that was a joke. In closing, it seems that Sony products are suffering substantial quality issues, and I whole-heartedly would advise anyone interested in electronics to avoid the Sony namebrand. Calls and E;mails were not returned. Sony did not stand behind it's product.
