I purchased my 62" TV in December 2005. Within 2 months I noticed a humming noise coming from the back of the TV. I figured it was from the fans cooling the TV and didn't give it much further thought. However, the humming noise became worse over the next few months and eventually got downright annoying. I contacted a service tech who determined the problem was the color wheel going bad and it will need to be replaced for a mere thousand dollars. Thank goodness the TV is still under the manufacturer's warranty. The part was ordered from Toshiba 2 weeks ago and it is still on back order with no definate timeframe for shipping. I guess they are too busy using the parts to put together more defective sets for retailers to sell. I will have to take solace in the fact I still have a TV to watch in the meantime, right along with the extra background "noise".
