I've tried posting this three times so sorry if it's now boring people. I Brought my FC60Z from JL two years ago, in the past two weeks i've noticed vertical curving towards the bottom of the screen from both sides. In addition a grey smudge has appeared about 5" in from the leftpointing downwards for about 6", it looks similar to a cleaning a really dirty set and missing a bit!. The repair guys are a good a my nan at splitting the atom. Any hints or tips?? Am I entitled to a new box if thety dont fix the big beast?? Thanks in advance.
