A couple of weeks ago i was watching my tv , as i turned the channel over i noticed a yellow key on the info bar ( dont know if anything to do with problem) i switched back to what i was watching and there was no picture so i flicked through the other channels to find all of them had gone, so i did a scan on my nokia dbox2 and it came up with "transponder scan successful" but there are still no channels available , the transponder scan only takes 1 second to do aswell if thats any help,, plz can somebody help me as i only bought this box six weeks ago and half of that its sat there useless because i cant get it to work .
