On March 24th Our 42" Toshiba HDTV went out on us. We also have had a 4 year extended warranty. The TV was purchased January 2007. We have been without a TV since The TV cost us over $2,000.00. We were told that 2 circuit boards needed to be replaced which would cost $500.00 each board and they needed to get authorization for the repair. After numerous phone calls, we are now told that one of the boards is backordered til May 17th. They refuse to replace the TV. So we now have a 42" TV in our living room, which will take at least another month before the parts come in from backorder, and then they tell us, THAT may not fix the problem...BEST BUY is a JOKE!!! any ideas from anyone???
