I've seen various threads on the topic re Sony TVs but haven't seen anyone publish a solution. Having just had my 36FS70 returned to me, after a 6 month repair, I now see I have scrolling black bars on he AV inputs. Before the TV died I reckon the picture was the best I'd ever seen on a TV. Now I have it back, the convergence is slighty off (was miles off before the engineer tweaked it), the colours look slightly washed out but worst of all I see scrolling black bars on all AV inputs. I'm assuming that some of the, many, new parts in my TV have added this bonus feature, I find some DVDs unwatchable, I'm beginning to despair of Sony. Has anyone actually cured the problem themselves?
