I can't remember exactly when I bought it, but I think it was around 2008
I have a DVD player connected to it, but use it only very rarely. My supplier is Virgin and I get my service through a V+ Box. The intermittent 'gaps' occur when I am watching a normal programme and when watching a recording on my V+ box.
I have to say that I immediately assumed it was the set which was causing the problem and only now realise it could be the V+box, so I have not had a go at Virgin.
Thank you indeed. Unplugged as you suggested, waited, and now all is well.
Super service for the totally untecnhical.
