Make a list of what is important to you.

Do you have the TV inset in an entertainment center so space will dectate size? Then mark down the dimensions.

Do you use cable (believe it or not, not everyone does!) If so you want it cable ready.

ALL TV stations must broadcast in HD by . . . I think it is 2009. Unless you are going to buy another set, make sure you get one that is HD. The HD picture on a non-HD TV will drive you nuts.

How far away is your seating from your TV? That will have an impact on what size you need.

Then go check out Consumer Reports at the library.

CR also has a TV buying guide on line, see here:

When we needed to get a new TV last August, I knew Dad needed a larger screen to see everything. But my TV is inset in an entertainment center. To get the largest screen possible, I wanted a model with the speakers ON THE BOTTOM, not on the sides. We got the Sharp Aquos LCD and LOVE it! And I use cable and subscribe to their HD service.

Good luck!
