Toshiba 50H71 50 in. TV

I have owned this unit for 1-1/2 years, and it has been a great TV - until it broke! The unit is easy to set up, has PLENTY of inputs/outputs of all kinds, and the 2 antennae input/1 output is great if you have satellite and cable. The unit has 2 sets of video and s-video inputs - and 2 sets of HDTV inputs. The remote is really clean and neat, and the buttons are well placed. BUT...I have had a picture problem and need to replace a circuit board. This board has been unavailable from Toshiba for over 4 months, and they have no idea when it will be available. And there response to my problem? "We can't tell you availability dates for backordered items." So if you have the picture "go south" on you, throw the unit away because Toshiba can't get you the parts you need.
