I have moved into a house with a Bush BTV17 TV/Video Combi. I also have a FreeView box that is plugged in and receives signal that plays through the TV fine.

However, I (stupidly forgetting that you used to have to tune the TV to play a video, having been used to DVDs for most of my life) just put in a video and pressed play. Ever since, the picture on the TV has been extremely 'wibbly' for both video and television. I can hear the sound perfectly for each, but no clear picture.

The manual has instructions on how to preset the channel, by pressing the CH Tuning mode, but I don't seem to be having much luck! Can anybody help?
