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.
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.
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 This occurs because the receiver retains the already stored channels in their previous frequencies [which are no longer active].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.
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.
