I have the HD LCD model 40X787. To program the channels I have to scan in analog and then the programing will associate it with the digital HD channels. What will happen after feb 2009 when there is no analog channels. How can I scan for channels?

    My HD TV is connected to an over the air antenna. I do not have satellite or cable. That is why it is so important that I find a solution to this problem.

The only people effected by the changeover are those that use external antennas for TV reception. I am assuming that you use cable or satelite correct?

    Based upon what I read in the manual, when the changeover takes place, the auto tuner will detect the lack of the analog signals but will detect the digital ones. You should not have any problems. This set is designed to pick up the digital broadcasts.

Why my jvc television hd61z456 not showing in high definition


What is the signal source that you are watching on your HD61Z456?
The problem you describe usually happens when you aren't using an HD source or have downgraded the signal by the composite input on your TV. (Composite cables only support 480i SD signals.)

You will only see 720p HD content from HD sources, if you use HD compatible inputs. Some OTA channels are also broadcast as only analog signals (usually the -2 and higher sub-channels). If you have cable or satellite, make sure that you have the HD programming and have tuned to the HD version of the channel.

The HDMI and component inputs both support HD signals.

I hope this helps. If you are watching an HD source and the problem persists, I recommend trying new video cables. Next, check if you are getting interference from your devices by using a cable with a Ferrite core. See http://www.monoprice.com/Category?c_id=102&cp_id=10240 for HDMI cables with Ferrite cores. The cores help block interference. If you have very long cable runs, check the behavior with shorter cables between the source and the TV.

How do I connect antenna for digital tv and program/scan for available channels


Hello Scott:
The unit must have a digital Tuner in it. This model do not come with a digital turner, so you are going to need a digital to analog converter box. And a High Definition Antenna. Once you have obtained these units go to your menu and select setup and switch to the the air mode and select channel scan.

No digital channels


This TV is not able to understand digital channels because its tuner is not able to find that band, it works only in analog channels. To be able to get HD channels is needed a decoder box that has digital tuner build in. for a tv to understand HD Channels with analog tuner is to us to try to speak at the same time different languages.

Cant program digital channels.


Nothing. Digital Tuners Broke. I wouldn't be suprised if your TV freezes up momentarily (or for a long time) when you switch over to the Digital Channels.

This TV has 1 tuner for analog channels and 1 tuner for digital channels. You can probably find the Digital Tuner on Ebay and replace it.

PROBLEM WITH GETTING LOCAL hd CHANNELS


You need to have a set top box.

By law, as of March 1, 2007, almost all televisions should include a built-in tuner (called HDTV, digital, or ATSC tuners) that can receive high-definition programs over the air by simply connecting an antenna. Your HDTV doesn't have such a tuner, you'll need to connect an external tuner (or cable or satellite box) to watch high-definition programming. External over-the-air HDTV tuners currently cost at least $150.

Get closed captions on some channels, but not all, even though it is CC


RCA have choices for different methods of CC in user CC menu. Labelled T1, T2, etc. . Different selections are for different types of close caption. Tune to a signal (on your other TV) that has closed caption working.

Tune your RCA to the same signal. Change the T1,T2, etc settings until the closed caption for your signal appears.

If this doesn't work, try connecting analog video or VHF channel 3 (or other specified channel) to the TV. check CC. When TV stations, sat channels, sat receivers, cable boxes etc, convert analog video signals to HD, problems can result. Some equipment causes RCA TVs to do unexpected things with sound and closed caption.

If you use RF or video output, old analog video may look better on CH3 or video than on HD input and the CC will work more consistently. Watch HD signals on HD input, Analog signals on Video in or through the TV tuner . Many HD channels and programs are converted analog video and look poor on TV HD inputs.

It seems to me that you are watchin an analog signal on a digital HD TV, the analog signal is has a standard resolution of 720x576 for NTSC (American Signal) and 720x480 for PAL (European Signal).

It could be worth to go contact your cable company, they can hook you up with a digital receiver which gives a better signal and might even have a HD Signal (this means it has a HD-Ready 1280x720 of Full HD 1920x1080 resolution).

If you really want to use your LCD TV on his max this is really worth considering
