Thanks for input jordon,Yes it looked like burn in mode.Tried pressing menu,but made no differance.Was going to put it to one side,as software prob.When read i came across a page where a 26" sanyo differant model, but doing the same thing.And he cleaned and reseated driver lead.And what u know it sorted mine too.I was sure it was going to end up software prob,so was gratefull.Its gone back to customer and all seems ok.
