Why only a few channels or no channel at all appear in Philips TV when I press the P+ or the P- button?

The P+ and P- buttons control the channels that are stored in the favourite list that was last selected. The channels that are not in that favourite list are not displayed. To watch such a channel use the numerical buttons on the remote control. To edit a favourite list:

1. Press the FAV button. The last selected channel list appears.
2. Press the red colour button. A list with all possible favourite channel lists appears.
3. Use the cursor up/down to select a Favourites (1 to 4) channel list
4. Press the OK button
5. Press the green colour button to enter the Edit mode. The selected Favourite list will bring up a full channel list.
6. Press cursor up/down to select a channel
7. Press the OK button to check or uncheck the highlighted channel and to add it to or remove it from your selected favourite list
8. Repeat steps 6 and 7 until your favourite list is ready
9. Press the green colour key again to leave the Edit mode. The modified favourite channel list appears. Press the FAV key again to exit.
