ACCESORIES AND WARRANTIES

With any large purchase, the urge to accessorize can be overwhelming. Here are a few add-ons to consider, as well as some words on warranty and shipping concerns.

• Cable requirements. In the store, you'll probably hear a salesperson tell you to get extra cables. Expensive cables will deliver an incremental boost in video performance, especially in reducing interference, but most viewers can't tell the difference. If your TV has component-video connections, however, you may want to consider specialized, relatively nice cables instead of standard RCA interconnects. Since component video provides the best picture quality among analog connections, it benefits the most from better cables.
• Surge protector. We definitely recommend shielding your TV investment with some sort of surge protector. Don't believe the hype that a better protector will somehow improve video quality, but do choose a model with coaxial inputs and outputs for your cable or antenna.
• Furniture. Many TV makers produce matching stands for their larger TVs. If you like their style, they usually make setting up the TV a lot simpler. That's because you won't have to worry about your stand being able to support the TV or being the right height for comfortable viewing from the couch.
• Other room treatments. Watching TV in broad daylight will result in a washed-out picture. We recommend that any viewing room be equipped with curtains or other window treatments that can block out some light during the day and that the TV screen face away from the window. Try to keep room lighting from reflecting onto the screen. A low-wattage light placed behind the TV in an otherwise dark room can make an ideal viewing environment.

The final question you'll be asked when buying a TV is generally, "Would you like an extended warranty with that?" Most savvy electronics shoppers will answer with a knee-jerk no. TVs are an exception however. With the numerous newer TV technologies becoming available and the high prices of HDTVs, it often makes perfect sense to spend a few hundred dollars extending the protection on your investment. You should still read the terms of the agreement carefully--the extended warranty should at least cover everything that the manufacturer's warranty does, just for a longer period, and may offer additional benefits such as preventative maintenance and free or low-cost repairs. Most extended warranties begin from the date of purchase and so may overlap the manufacturer's warranty. When deciding whether or not to purchase an extended warranty, the ultimate decision is whether the cost (usually $200 to $600 or more for a TV) is worth the coverage the warranty provides against whatever risk you expect the TV to be subjected to. That's a decision only you can make.

The standard warranty covers parts for one year and labor for 90 days. Some manufacturer warranties have separate time frames for the picture element--such as the tube, which is often covered for two years--and the rest of the TV. High-end TVs, especially plasmas, often have a one-year labor warranty. Some manufacturers also offer in-home service on more expensive and larger models that are difficult to ship.

An increasing number of TV makers are cracking down on "unauthorized" retailers of their sets, especially online, and some will not honor warranties on products purchased from such dealers. See the Web site of your set's manufacturer before you purchase a TV online for its policy on unauthorized retailers. Many cut-rate online vendors don't allow you to return televisions under any circumstances. Before you buy online, read the terms of the return policy carefully.

If you decide to buy your TV online, be prepared for a significant shipping fee. You should also consider how to get it through the door and set up in your room or on a stand; big TVs often require more than one strong person to lift them. Some online and many brick-and-mortar dealers will move the TV into your house and even set it up for you, but it usually costs extra.
