Digital Tuner Unable to find whether or not Sharp 20F640 TV has a digital tuner. Is it high definition compatible?

Unfortunately, you cannot convert an analog TV to digital simply by changing settings. The transition from analog to digital involves hardware changes. If you have an older Sharp TV without a built-in digital tuner, you may need an external digital converter box or consider upgrading to a newer TV with a built-in digital tuner to receive digital broadcasts.

Terminals and Connections Dual HDMI digital inputs with HDCP (High Definition Content Protection) offer an uncompressed solution to the transmission and display of high definition video and audio content. All JVC HD-ILA TVs also include dual auto sensing component video inputs, assuring the best possible picture quality whether a viewer is using DTV, D-VHS or DVD, and three S-Video (two rear, one front) inputs and four AV inputs (three rear, one front).
High Definition Multimedia Interface
HDMI is a new standard digital connection between A/V devices, such as a set-top box, DVD player or A/V receiver, and a digital television. HDMI offers exceptional video and audio quality with a single quick-disconnect connector. It supports multi-channel digital audio transmissions and component video color spacing for true rendering of HD video.
We carry a full line of high-performance HDMI cables. See them here...
Audio Features The JVC BBE High Definition audio system with Advanced HyperSurround and Active Hyper Bass includes two direct-drive speakers mounted underneath the screen for rich, expansive sound that fills your home theater or TV room.

Make sure you have a good connection from antenna to TV. Check antenna and cable and cable connection to TV. Select DIGITAL button on TV remote when wanting HD channels. Remember HD channels are always digital. Also, any given TV station may not be broadcasting in HD at a given time. They can broadcast in digital but in standard definition sometimes. Your TV has a built-in DVB-T tuner. Try executing a channel scan to pick up all available channels. On-screen menus go to Digital Setup, then Digital Tuning, you can auto-tune or manual tune channels. The TV should take a few min. to scan thru available channels and store the channels its finds. Check with anyone in your area to see if they get HD channels (it is possible to be outside of the range of some TV stations) Your TV is a 2006 model and should still be compatible with local digital TV broadcasts but keep in mind digital signals could change in the near future (DVB-T2) and you may need a tuner/converter box to make the TV compatible.

Your Hitachi 51UWX20B is an HDTV-Ready TV. No Digital Tuner. HDTV-Ready means that your TV set is capable of displaying analog and high-definition digital pictures, but without a digital tuner, it cannot receive the digital signal. An HDTV-Ready requires an external high-definition TV receiver (digital tuner) in order to receive HDTV signals. These external receivers can be called an HDTV Tuner, set-top-box, decoder or DTV Converter Box . So you will be required to purchase a converter box to receive over the air programming from an external antenna.

https://www.dtv2009.gov/FAQ.aspx What you need to know is whether your TV set has something called a “digital tuner” already built in. If it does, your TV set will work after February 17, 2009. The best way to determine whether your TV set has a digital tuner built in is to consult your owner’s manual. If that’s not possible, you may be able to look up information about your TV set on the manufacturer’s website. Or, you can take an up-close look at your TV set. In any case, you’re trying to find out if your set has an input connection labeled “digital input” or “ATSC” (for Advanced Television Systems Committee, which is the DTV format).

Here are some general guidelines that may help:

TV set made before 1998 was a traditional “analog” set. If you bought a big-screen, projection TV between 1998 and 2004, it may have a built-in digital tuner inside. But chances aren’t great. Only a limited percentage of projection TV sets (and generally only those 42 inches in diameter or larger) included digital tuners before 2004.

If you purchased a new TV set since 2004, your chances of having a built-in digital tuner improve dramatically. Starting in 2004, many of the TV sets sold at popular electronics stores feature digital tuners that will work after February 17, 2009. But it’s not a sure thing. Even some of the newer TV sets are purely display monitors that lack the internal circuitry needed to pick up digital broadcasts. Usually these sets have been advertised as “HD-ready” or “HDTV monitor” sets. That means they can display digital and high-definition signals, but they need help getting those signals in the first place. You’ll still need a special converter or a cable TV connection. Hope this info above helps. Also, check your manual, and if you don't have it some manufacturers, (Philips does for some models) offer the manual on their websites.
