Sadly no change?
However............I. have just tried a DVD and that is the same so it seems my problem is between the amp and the TV , further investigation needed.
I think I may get a better quality hdmi lead for the amp to tv connection, the original which is now too short is a QED Quinex cable but the one I am usin now although it is new and unused before was, Think one of the thin black ones that came with the stb?
