Does anyone know how to do a full factory reset of the Sharp LC32GD8e? Earlier this year, our Sharp started to display bright green areas, after calling support it turned out this is a software fault which can occur, for which there is a firmware update. They sent an engineer up and he did a factory reset first by pressing some buttons at the top of the TV while turning it on. This fixed the problem, and he said it shouldn't recur, however to be on the safe side he also updated the firmware. My parents have the same TV and theirs had been OK until now, and it has now started to exhibit the same behaviour - unfortunately it's out of warranty! Does anyone know what the magic keypress is that allows you to do a full factory reset of the TV? (Not just the reset through the ordinary menu, as that doesn't fix the problem). I noticed another post saying that you hold down Vol-, Ch- while turning it on, but I've tried that and it doesn't seem to work... Also, anyone know of a way to get the firmware updated out of warranty? would it cost a lot? Thanks, Colin.
