 Buying a new piece of electronics can be exciting – it’s an opportunity to explore new features and update your home. But sometimes it's daunting, particularly when there is a wide range of options. And now for those who don’t already have TV sets that can show digital broadcasts, we have to convert or buy new ones. As of February 17, 2009, all analog signals will cease from television stations across the nation, so we all have to get on board with digital technology (either via a converter or a new TV) in order to keep watching our favorite network TV shows.
Buying a new TV should be easy, right?

Most people will want one of the first three.

Beginning February 17, 2009, all full-power broadcast stations will cease analog broadcasts and only be viewable through a digital tuner.
How do I know if my television has a digital tuner?
If you purchased your television after May 2007, your set is likely equipped with a digital tuner or your provider would have been required to let you know you would need a converter box.
If you are unsure if your set is equipped with a digital tuner, you can check the owner's manual or your manufacturer's Web site. You can also look for an input connection labeled "digital input" or "ATSC."

 The next time you walk into the room where your new flat-screen TV is on display, take a good look around. Is it starting to look dirty? Between all the dust and lint that flies around the average room and the dirty fingers used to turn the TV on its mount, it doesn't take long before the set needs a good cleaning.
But don't be tempted to use the same methods you would to clean your tube TV. Flat-screen television sets require more specialized care. Here are a few "Dos" and "Don'ts" to keep in mind:

 You've got your new large-screen HDTV set up, and you have plenty of your favorite DVDs waiting to be viewed. Now all you need is the right sound. When you sit down to watch a movie -- or live music concert -- in your own home theater, you want to feel as though you're in a real movie theater. The audio is just as important as the picture quality, which means you should take great care in shopping for the right receiver and speaker pieces. As you shop for audio components for your home theater, first check out "HDTV – A beginner's guide." Then, consider the following points:
The AV receiver
Most average home theater users don’t need to buy separate tuners and amplifiers for the different channels. The easiest and perhaps most cost-effective way to get several pieces all in one package is to go with an audio/video receiver, which lets you plug in most, if not all, of the pieces in your system, including your television.
