Hi Nick
I wouldn't have thought that would be the cause as it was working
fine and then wasn't. It was on an A frame the whole time and hadn't
been moved.
That said... never trust a client who says they've not done anything
to cause it. ;-)
I'll give the boards another once over when I've got it back up on
the bench.
Thanks for the input
Much appreciated
Bob
thanks for the tip.

damage when replacing IC's.
