It has a rather nifty pull-out-and-twist LCD screen. Unfortunately, because the screen gets twisted the wrong way, some of the wires inside have now broken and the screen now doesn't work at all, which means that what I've got is basically an expensive point-and-shoot camera because I can no longer see to change even the settings I know about, and I can't review the pictures without using a computer.
I've had a good look at it and I think I don't really know how to get at the broken wires to fix them, and if I did I wouldn't know which order is the right one to join them back together in (as they are all black).
I'm guessing a professional repair wouldn't be worth the money (although some people seem to disagree). I should think it would take an expert a couple of hours to get the thing apart and put it back together, provided they happened to have a ready-made replacement cable handy. The G3 seems to be worth about £100 on eBay, though being four years old it is somewhat dated compared to today's offerings (I think that series is up to G9 now). However, I'm not sure I ought to be spending any money on cameras just now (this fact won't necessarily stop me I'm sure).
So… repair, replace, upgrade? What do you think?
