Television technology has changed drastically since its inception in the 1940s. Vivid color and hundreds of channels have replaced the limited channels and snowy black-and-white images of early network broadcasts. The method for sending broadcast signals has also changed. In order to free broadcast space for emergency services and provide a better viewing experience, the FCC has mandated stations to switch from analog to digital broadcasting. With the change, some televisions may not be able to receive a digital signal. Checking your TV to determine if it will receive digital signals is a simple process that only takes a few minutes.
Instructions
1. Examine your TV to determine if it is a standard CRT/analog set or a newer model. If you own a newer, wide-screen TV, check for a sticker or marking that states "HDTV," "SDTV" or "480i." If any of these are posted on the unit, receiving a digital signal should not be an issue.
2. Check the user manual for information about your model. If you have lost the manual, download it online (see Resources).
3. Determine if your television was manufactured before March 1, 2007. If so, it's unlikely to have the digital tuner necessary to receive the proper signal.
4. To continue using your current analog television, install a DTV converter box to receive a digital signal. Converter boxes are available at most retail and electronic stores.
