A checklist for switching from analog to digital TV: Remember to re-scan for channels

Checklist for switching from analog to digital TV

Here’s a checklist to make sure you’ll have TV reception after analog broadcasts end Friday.

— Are all your TVs hooked up to cable or a satellite dish? If so, you’re OK.

— Do all your TVs have built-in digital tuners? Most TVs bought in the last few years, including flat panels, have these. If they do, you’re probably OK. But you’ll need to force your TV to scan the airwaves to find all channels, because some are moving to new frequencies.

— Do you have an older TV without a digital tuner? You’ll need a converter box.

— Do you have digital converter boxes hooked up to older TVs, and you get some but not all the channels you expect? You should force the box to re-scan the airwaves. Some converter boxes don’t scan well, so you may have to key in the channel number manually. Check the box’s directions, and look at www.antennaweb.org to figure out which channels should be available in your area. Re-scan periodically to pick up stations that move frequencies after Friday.

— Still having problems getting all the stations you want? The problem may be your antenna. Outdoor antennas properly pointed toward a TV tower are preferable, but indoor antennas work if you’re reasonably close to the tower. Antennas should be capable of receiving both VHF and UHF signals — some older ones are VHF-only, and some sold specifically for digital television are UHF-only. Modern indoor antennas are available from $40 to $100.
