I had a power cut this afternoon and my DishTV Satbox Ultra S7090PVR has lost most of the FTA channels. I now only seem to have TVNZand its offshoots like U plus Trackside nothing else. Have tried a rescan and it appears to detect other channels but when I go back to main screen all I find are the TVNZ stuff again .
Do I need to do something other than just scanning FTA
