My son very kindly preesed the factory reset default  over the weekend, I was not happy and would have happily pushed him off a nearby coastal cliff!!! 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! Tony
