Bring your cameras in for main board replacement.

People start reporting Canon services replacing main boards of their faulty 5Dmk3 cameras upon receiving, indicating the replaced part number as CG-3158-000 named in the supporting post-service papers as “PCB ASS’Y, MAIN”. I'm collecting these documents - if you have one from Canon following your cameras fixed, send it to me to maxim.drygin_at_gmail.com At this stage Canon reps are quiet on confirmation the main board is at fault as per my request, which could mean they are either waiting for more cameras brought for inspection to verify this internally before going public, or they simply ignored my request as “no comments” strategy works a treat for a big fish when numbers of protesters are lower than estimated numbers of products affected. Keep pushing the message through, guys, share it with everyone you know who owns a 5Dmk3 - and ask them to fill their serials in this survey http://www.surveymonkey.com/s/KHKR2XS Cheers Max
