Retuning

How is retuning done?

Note that each device [brand] differs and may therefore follow a different procedure for the setting of channels. In the steps below the most common “wording” found on TV sets and decoders is used, therefore if you require more specific information you will have to read through your device’s manual.

To set or retune your receiver a few simple actions are needed.

  • For TV sets with integrated MPEG-4 decoders
  1. On your decoder’s remote press the button with the label “Menu”.
  2. Select «Settings».
  3. Select “Automatic Tuning» to automatically find and save available frequencies. Depending on the device, this option may be referred as “Automatic Search” or “Automatic Scan”. Alternatively, if you wish to save the frequencies on your own, you may choose “Manual Tuning”.
  4. Press “OK” or “Yes” or the corresponding function on your device to complete the process.
  5. Press “Exit» to exit the menu.

 

  • For TV sets with external MPEG-4 decoders
  1. On your decoder’s remote press the button with the label “Menu”.
  2. Select «Installation”.
  3. Select “Automatic Tuning» to automatically find and save available frequencies. Depending on the device, this option may be referred as “Automatic Search” or “Automatic Scan”. Alternatively, if you wish to save the frequencies on your own, you may choose “Manual Tuning”.
  4. Press “OK” or “Yes” or the corresponding function on your device to complete the process.
  5. Press “Exit» to exit the menu.

 


Potential problems that may appear on your decoders and recommended solutions

While going through the retuning/rescanning process you may encounter some problems which source from the way that each receiver searches and stores the digital TV programs.

Some of these cases are mentioned below, along with some steps for their resolution.

 

  • Black screen after retuning

The name of the channel/program appears normally, however the receiver projects a black screen while no sound is available. This occurs because the receiver retains the already stored channels in their previous frequencies [which are no longer active]. As a result, when it identifies them in new frequencies during the scanning process, it ignores and does not store them.

Solution:

Delete all stored programs and undertake a new program search/scan. Alternatively, you can reset your receiver to its factory settings [use your instructions manual for guidance] and then proceed with the new search/scan.
