80D Built In Flash Pops Up But Won't Fire

[Toznator]

The built in flash on 80D pops up in Auto mode but won't fire.  I put "built in flash on" in the on mode and it will pop up but not fire.  I have been using 430EXIII RT and everything has been working fine.  Been shooting in P mode and built in flash and 430 have been working well.  Not sure if I have pressed the wrong button or what but I sure do need some help.  Thanks in advance.

What was the result of inspection.  I too have can not fire built in and am having problems with external flashes now.

Hi bscholberg,

Canon repaired the camera at no charge.  I still had to pay for shipping and insurance to the service center in Costa Mesa, CA but return shipping and insurance was paid for by Canon.  The camera was repaired in the Boston area and returned within seven business days which seemed fast as it was necessary to disassemble the top part of the camera.  Everything is working now and I am happy with Canon's service.  I don't know but I suspect a component, quite possibly the flash itself, was replaced.

Thanks.  Mine is not under warranty, was yours?

[eyemo]
