The channels for a digital stations are really just "names". Thy will be the number for the old analog channel followed by a "-" and a number 1 through 4. The actually frequency can vary
from the old frequency. You can see this at;

To set up your tv, you will have to connect your signal source (Antenna or Cable) to the set.
Go into the menu and select the Signal source (Channel) to match what you connected.
Go into the menu for scan or auto program and SCAN in the channels in your area.
Now you can watch the stations on your set.

If the broadcast frequency of any station change, you can re-scan it in again. The "name" will not change so the change will be invisible to you.

What does RF CH mean?


What is the difference between a RF channel and a virtual channel? The RF channel is the channel that the TV station uses to broadcast its signal. Before the conversion to digital, TV stations were normally identified by their channel number, and most people knew that a particular network was on a specific TV channel. While analog broadcasting was being phased out and all TV stations were converting to digital broadcasting, it was necessary for the TV stations to continue to broadcast their analog signals on their original RF channels, and also broadcast their digital signals on a different RF channel. However, since the TV station used their broadcast channel as part of their identification, they wanted to keep using the same channel number. To allow this to happen, the new digital television broadcasting standards (ATSC) provided TV stations the ability to continue to use their original channel number and also tell the TV set to tune to the new RF broadcast channel when their virtual channel number was selected. The original channel number is called the virtual channel number, and it will be followed by a period and a second number (3.1, 7.1, etc.).
One of the benefits of converting to digital for the TV stations is that they now have the ability to transmit more than one program at the same time on the same RF channel. The number of additional channels they can broadcast is determined by the resolution of the program (SD vs. HD, text only, music only, etc.). The second number in their virtual channel number indicates that one of the additional programming sources from the same TV station is being viewed (10.2, 10.3, 10.4, etc.).
When selecting an antenna, it is important to understand the difference between the RF broadcast channel and the virtual channel. Antennas are designed to receive specific ranges of RF channels, and the antenna needs to be selected for the RF channel you wish to receive. TV stations broadcast in two broad frequency ranges, called VHF and UHF. RF channels 2 through 13 are considered VHF, and RF channels 14 through 51 are considered UHF. In order to pick up the channels, the antenna has to be designed for the correct frequency range. It is very common today to find that TV stations using virtual channels 2 through 13 are actually using RF broadcast channels in the UHF range. Although not as common, some TV stations using virtual channels 14 through 51 are actually transmitting in the VHF range. An antenna designed for only UHF channels will not work effectively for RF broadcast channels in the VHF range, and an antenna designed for only VHF channels will not work effectively for RF broadcast channels in the UHF range.

Channel numbers missing


local channels are usually below a channel 1000. they are always on same assigned channel. If your cable box or tv has it, it has option to not display channels with no service on them. you can't reassign the channel numbers. they are channels but not being displayed.

Sony bravia no digital channels


If you've tried different antennas did you attempt to re-tune/re-scan for additional channels after switching? For digital channels to be detected they must be scanned for, so consult your manual on how to perform an automatic scan of the digital channels available in your area.

Sony Bravia Digital TV won't tune Channels 350 and 350, can't manual tune wither as it will only accept 2 digit numbers, even though it tunes 201 ...


These numbers are the LCN (Logical Channel Number) assigned by the broadcasters. It will only be at 350 if it is the same channel from a different transmitter. You need to know the 'channel' of the frequency to manually tune it in. You are talking about the program number not the channel (frequency), a common mistake. i.e ABC in Sydney is transmitted on CH12 (226.5Mhz) and the LCN's for each program are 2,21,22,23,24,201 & 201. If your antenna also picks up the signals from the Kings Cross transmitter ABC is CH30 (543.5Mhz), as these are later in the spectrum they are put in the LCN list starting at 350.

We are in Ghana we need frequency and we update to get more channel


Your flat panel TV is probably factory set to receive ATSC signals (Hi-def DIGITAL TV), whereas
Ghana may not have converted from analog TV (NTSC) yet.

Digital TV's cannot receive analog signals. I'm just guessing about whether or not Ghana supports
Hi-Def broadcasts - you'll have to check with (any) TV channel in Ghana. The Analog-to-digital
conversion is an expensive one at the broadcast end, and may not have happened yet in Ghana.

The US conversion took place by FCC mandate June 12, 2009.
There are available $65 (USD) digital-to-analog converters, but what you may need is an
analog-to-digital converter, which doesn't exist. Your Flat-panel TV amy have to wait until Ghana
begins broadcasting a Hi-Def TV channel.

For a HD antenna, a regular old rabbit ear-type antenna will do.

I have a polaroid hdtv model TLA-d1911c that wont get a local channel.I bought a new antenna and hooked it up but it still wont pick anything up.


You may be looking in the wrong place or have the wrong kind of antenna. With the digital conversion, TV channels shifted from the numbers they used before. In my area, the previous Channel 6 is now broadcasting in the UHF band.
It can be harder to adjust the antenna for a digital TV because it is either working well or totally off - no gradually decreasing "snow" as a clue.
It is possible your TV is not equipped to pick up digital TV. There are converters to translate digital TV to analog signals for older TV. They cost between $30 and $70 depending on features.

Directv Samsung problem


I also have directv.At this point,it is a video signal issue on their end.The up conversion is ok at best.Depending on the original video that is probably as good as it gets.The other problem is the wow factor from hd.It is hard not to be critical of the non-hd channels.
