Hi there. I realise this is somewhat of an old-school telly to be asking about (what with all these young whipper-snapper KDFE42A12Us knocking around) but I thought I'd ask anyway. I've recently inherited (quite literally) one of these beasts and am very happy with it. The only issue I have is that the convergence seems to be off. It's fine in the centre of the screen but really quite far out around the edges and especially in the corners. I realise a bit of de-convergence around the periphery is inevitable with sets like these, but I've also been told that it's possible to do a 'full-screen' convergence using the service menu (the standard menu only allows you to converge using a cross in the centre of the screen). I have a service manual but it's pretty technical. Can anyone offer any pointers on converging the set using the service menu? Is it even worth it (ie will I see a noticable improvement by doing it)? I'm not really in a financial position to replace the telly, so would really appreciate any hints on how to maximise what I've got . Many thanks, Djhavor.
