Closure lasted longer than the motherboard!

Did the Canon EOS 40D is now almost four years. She was me with my Journalists always a faithful and reliable companion. However, she has now given up the ghost after approximately 40,000 releases. It was unfortunately the motherboard is defective, the closure Canon would have replaced.

Postscript: Fortunately, she could repair a small shop in Bavaria me now, I should at Canon namely shell out 380 Euros for repair. Therefore, the DSLR will now continue to be used regularly.

Unfortunately, in this model, the serial number is gone after a short time on the model label (inkjet printer?). An impressed number would make more sense, because I could only read with a ExifTool the number. Canon calls this number namely during a repair.
