On-camera flash on my 7D had intermittent problems, now the problem is permanent. This is a good 
news for me, getting even with the Canon service center; in the past rejected with a smile implying a con, failed to reproduce the problem on the spot, surely you’ve experienced this embracing feeling, I would have my satisfaction now, rejecting the repair no longer possible, proving that the con is Canon service center, set up in a way allowing them to dismiss an intermittent problem without making a proper effort in reproducing a problem, exhibiting a disturbing pattern, finally having my camera repaired and, hopefully, working properly in a few weeks.
