Hi.
Just wanted to thank all the replies. I have just returned from a weeks holiday down in south Devon, I had to phone a friend to log in and ask the original question on my behalf, hoping that i could get a quick result. being in the Salcombe area the nearest camera shop was some 26 miles away, or at least thats all i could find from locals.
The D80 had just been handed down to my son so was disappointed that it let him down after so many yrs of no problems.
The Err message appears all the time with or without a lens attached, shutter opens but no picture shows, cannot change M A S P or anything from that dial.
Back in Norfolk now so its a visit to the local camera shop, and will have to except the worst.
