You're a handy man to have about then :)

I just sucked off the old solder and put new on - it's nice and shiny now.

Yup, I went over everything that was dull and tired looking. The only real
cracks were the ones I photographed. Having gone over the PSU and logic
boards I got it all back together last night and it's sitting next to me now
running my second desktop. So far it's producing a much better picture than
the the Compaq monitor I'm looking at now.....which is 4 years younger.

So it's been repaired before then.....

'tis a 2 year old Fuji 6800, possibly the last half decent camera they
produced before coming up with the awful A601. Works best on a tripod though
- those pix were hand held so I'm surprised they came out so well!
