Most places listed "1 tuner" in specs. Was finally able to find a site where it listed the type of tuner which confirmed that it was not HD compatible. That was all I needed. Sorry I troubled you with this, I shouldn't even have been on your site with this Q. Thanks for responding. Potter1

Hi, I live in a flat in London with a shared rooftop aerial (no idea of spec). I have a Sony KDL-46X2000. The built-in freeview tuner doesn't seem to recieve any HD channels. Is the built-in tuner the...


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.

I would like to know if the Hitachi 51UWX20B television can be connected to the internet.


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.

I don't know if my TV's digital tuner will work when they switch over to digital broadcasting. My TV does have one but during a test it didn't work


The Sharp LC-19SB25U 19 in. HDTV LCD TV has both a NTSC and an ATSC tuner.

The NTSC tuner will stop working in Feb. 2009 but the included ATSC tuner is what you need for after the digital transition.

If this is not the model number or manufacturer of your TV, then please post them.

How do i convert my dtv-5801 to the new free digital air waves


My information indicates that the DTV-5801 has a NTSC (analog TV) tuner built in bot not and ATSC (digital tuner). It does have HDTV inputs to which an external tuner can be connected. For Off-Air Digital TV, add an HDTV (ATSC High Definition tunner) and you are set to go. Do not buy the DTV converters, they have down converters built in and only deliver SD to the outputs.

Is my tv digital compatible or not


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.
