maybe you can help me.
I am an electronics technician,
I have already repaired 2 times my flash 580ex ii,
once the xenon tube and another time the IGBT. everything was fine.
Then following some hummingbird shooting at 1/8000 sec
my flash returned to full power only, manual, automatic, no more strobe, but the hss always founds a full power.
I still changed the IGBT, although it was not logical since the hss worked well, and check the optical cable,.
I always remain at full power.
Thank you for your help if you are the technician and repairer of these models
