The box attached to our TV that we use to record programs has died a death. We changed the fuse and it came alive for 10 mins but it has died again. As it happens, we only got it last week from John Lewis to replace our first one that also broke down. I had hoped this was a new one, as we were within our 2 year guarantee, but looks like it is maybe a reconditioned model. Of course, they are shut today and it will be pandemonium tomorrow. Any wise words?
