My TV is approx. 2 years old and is described as LCD. My question is when all signals go to digital next February, will my TV perform in HD since we have Comcast cable connection? My other TV's have 2 different connections--coax and HD...the LCD set only has coax.
If the LCD only has coax, it will never display a HD picture quality. However, the Comcast HD Box will still display a picture using the coax connection. So, you could watch any HD channel, but the picture quality will not be high definition.

If the cable provider is sending digital signals a TV that old will not be able to receive them. If they are not digital signals they may be encrypted. You may need a cable box from the cable provider or use a DTV box to get free over-the-air digital broadcast signals.
In Australia analogue TV signals will be phased out and finished by the end of 2009 (I think).
If you have a standard analogue TV you won't be able to receive any more free to air analogue TV programs when they stop brocasting these TV signals. To recieve the new digital signals you need to buy a digital set top box (which receives digital TV signals and converts it to analogue signal that can be displayed on your old TV). The set top box will only receive Standard Definition signals and this is a lower screen resolution that is available from High Definition signals.
Digital TV signals offer approx. 15 TV channels ln High definition and Standard Definition, different programs channels will be available from the same TV broadcaster, although the High Definition pograms will also be repeated on one of the Standard Definition channels.
High Definition gives a sharper image than Standard dedinition, but you may not notice much difference because it depends much on the material you are viewing, You will notice how clear DVD and BlueRay movies are compared with the VCR tapes. To get the best images from DVD movies your player must be connected to the HDMI connector on your High Definition TV (provided your DVD player has one, usually BlueRay players will have one, they also will play normal DVD disks).
If you purchase a new High Definition TV you will also be able to receive all the Digital TV programs. Currrently these TVs are avail in Plasma or LCD screens and there are newer technologies within a few years. The Plasma screens use twice as much energy (electricity) as a LCD screen. It is suggested that the viewing distance to the TV should be 3.5 times the size of the TV screen.
Hope this answers your query.
Get back to me if you have any more questions.
The digital tuner has nothing to do with the new signal you will be receiving in February of next year. The new video signal is a digital signal. The old video signal is analog. Your television receives the analog signal and converts it to what you see on television. You need a converter box to convert the new digital signal back to an analog signal your television can convert.
Had the same problem. The solution: My remote has a button labeled "TV/VIDEO". I must have accidentally pushed this button so when I turned the TV on it was searching for the signal from a VIDEO source. It couldn't find the signal so it's programmed to automatically turn off if no signal is received. All I did to solve problem was I turned TV on and before it could turn off by itself I pushed the "TV/VIDEO" button on my remote to switch it back to receiving TV signal.
Great question! First think to know is that if you are getting your programing from a cable or satellite provider a digital converter box would not be needed. These services are not being required to change their signals. If you use rabbit ears or an antenna a digital converter maybe required.
Looking at the specifications of your televisions they all appear to have analog tuners which would need digital converters to receive the new digital broadcasts.
Thankfully the FCC does have a program in place to offer coupons to assist in purchasing the new converter boxes.
Not if you cable TV, DirecTV, Dish network, or FIOS. The converters are not usable with those services.
If you use a regular TV antenna or rabbit ears, then, yes, you will need a DTV converter box. If so, I'd suggest getting one well before next February. Why? 'Cause the pictures are better, and you'll have access to "virtual channels", where broadcasters send more than one program on channels like 4.1, 4.2, etc. Also, if you have poor reception, you may need a better antenna to see the DTV signals. Better to know that before DTV is all that is being broadcast over the airwaves.
