After successfully screwing up my previous set when using the service menu, I've had to get a replacement. My old Philips set had perfect 4:3 vertical geometry but quite poor WS 2.35:1 Horizontal geometry (which I tried to fix hence the whole screwing up thing). I've got a replacement set however, this new set has noticably worse 4:3 vertical geometry than the previous set and still has the same poor WS Horizontal geometry. I was better off with my old set (typical !). Im now gonna have to head back into the service menu to try and improve the 4:3 geometry. While it doesnt bother me when watching 4:3 TV programs, when watching WS films door frames and objects in the background which should appear vertically straight bend inwards, so this needs correcting. What I need to do is bend the sides outward slightly at the top and bottom, however I cant remember which settings have to be changed to do this and Im reluctant to mess about with all the settings until I find the right one because last time the whole set went kaboom!. So can someone help me out with which settings I need to change to alter the top and bottom virtical sides in 4:3 mode ?. As I have no idea why my set went crazy last time I entered the service menu Im not looking forward to this at all. Any advice as to what could have gone wrong and how to avoid it from happening again would be nice. Really wish I'd kept my old set and left it alone now.
