Hi,Does the icon look like a large satellite dish?
Make sure your TV is on "TV" and not "DTV" before retuning.

To re-tune analogue channels:

I have a Samsung TV and that icon is not accessible from the menu if i am watching the tv on the digital option of my remote. You have to switch your tv to the "tv" option on your remote and you will be able to access the icon from your menu.
(on your remote, you should have a button with TV/DTV on it)

To re-tune analogue channels, if you want to re-tune digital channels, then look for the "D MENU" button on your remote. Press this then scroll down to the icon that looks like a large satellite and then on "Auto Store" This will re-tune your digital channels :0)


Take care and hope it helped.

Try using manual tuning. Be sure the channel type is on TV or CATV, then store the channel.

uhf and vhf tuning is performed in one board(tuner brd) there are some on line part stores that can help you with the number and price, you'll need to provide the model number. partstore.com is one of them, but there are more.good luck.

When TV channels are moved from one frequency to another frequency that was previously used by a different channel (sorry, but there's no simple way of saying that !) as has happened recently in th UK, some digital TVs and digiboxes struggle to sort the channel list out properly and channels can go missing as you describe.

If your equipment has the option to delete all currently stored channels (normally in the tuning menu options) then do so and then do a full re-tune.
Sometimes, this solves the problem as the equipment is no longer aware of any previous use of a frequency and just loads every channel it finds.

If this doesnt work, or your equipment doesnt have the option, then there is normally the option soemwhere in the menus to retore the item to "factory defaults/configuration". This will clear all previously stored channels and after a full re-tune your missing chanels should be there. However, any other configuration changes you previously made, e.g picture size, output type (RGB/NSCT/etc), etc will be lost and you'll need to set these again.

NB. some regions of the country have lost some channels temporarily now until after the switch over programme completes at the end of 2012. If you visit the Freeview website, this will tell you if your area is affected.

The retuning process is as follows:

1. Press the [i+] or MENU button on the remote control to display the DIGITAL INFO menu.
2. Press the BLUE button to display the MAIN MENU.
3. Press the UP or DOWN buttons to highlight AUTO TUNING then press the OK button to display the AUTO TUNING MENU.
4. Press the RED button to start the auto tuning process for all available digital channels.
5. Wait for the process to complete.

If you wish to CANCEL the auto tuning process whilst it is processing then press the BLUE button at any time.

You may lose some channels when you retune the TV as the channels have been rearranged. To locate them look at the EPG although you may still find that some channels are no longer available on FREEVIEW. See the following link for additional information

If the above process does not work then check the link above for additional information and also visit the accompanying site links below to find more information for your model of TV / FREEVIEW box.

It is working as designed. The purpose of your cable box is to take in a wire containing all of the possible channels you might watch, and then extract *one* channel, and force it to appear as channel 3. If you connect the cable directly to the VCR, then the VCR's "tuner" (ie, channel selector) has an opportunity to extract any channel it wants. But... as you point out, your VCR won't be able to "see" any of the digital channels. So... if your goal is to be able to watch any of the digital channels, the signal must pass through your cable box, which will put the selected channel on channel 3. There is no value in going from the VCR to the cable box, since the VCR's tuner will have already filtered out all but one channel. It would be helpful to make a list of what your useage goals really are, since there are so many different ways to hook these things up. Are you interested in: - watching digital channels? - recording digital channels? - watching one channel while recording another? - using higher quality video signals (composite, s-video, component, etc) rather than RF (ie, channel 3) And so on. Keep in mind that you have *three* tuners: Your cable box, your VCR, and your TV. It sounds like only your cable box can tune in the digital channels. If your cable box puts out any non-RF signal, then the best choice would be to go: Coaxial Wire -> Cable Box -> Video Connection -> VCR -> Video Connection -> TV, with the VCR and the TV both set to "video". Then you would only use the cable box as a tuner, the VCR would only see the tuned channel (via video in), and the TV would see the same channel (or whatever tape you are playing) on its video input.
