My 42"HD wont power up,its a model WT-A42, the production date is 2002.Bought it in 2003 at Best Buy. The green light comes on for a few sec then turns off. Heres my question, I had a repairman come out, spent 20 mins and told me the minimum charge to fix it would be $568.00 that he would have to take it in and run tests but he knew it would cost at least that much. Does that sound right? This really sucks. Any help will be appreciated.
