So, it was a 'ball acher' reloading all the tv channels etc -- I only use french TNT and Free to air sat transmissions being a tight northener originally.
Ok, it took time, but on looking at the tv transmissions I was amazed to see that the reset had resulted in a much better picture and sound.
I have always assumed that the set was on factory default but now I suspect in its past someone has been playing around with the settings in the hidden engineering section menus.
I think I am only the second owner of said tv but am now a very happy 'bunny' bearing in mind the cost to me of said unit.
I am now inspired to get my BC2 rebuilt and recommissioned.
Sorry for my ramblings!
