| p.1 #1 · Speedlite 580EX problems... Overheating? |
I've recently started to run into issues with my 580EX (v1) Speedlite. I turn it on, with freshly recharged batteries, and all is well, the pilot light goes red, and I can shoot, except that before I get a chance to shoot, the pilot light goes off. Or sometimes it flickers between green and red for a while. But eventually it turns off, and I can't use the Speedlite at all.
Occasionally I have been able to get a shot off, and it has worked fine (even using wireless master and triggering a 430EXII), but the pilot light's eventually just turned off and the flash doesn't fire. The flash still works otherwise - I can turn the backlight on/change settings etc. it just won't fire.
Any thoughts on what may have occurred? Or has anyone else had a similar issue? I would hazard a guess at some sort of overheating after a bit of Googling, but that doesn't explain why it works for a small time only does it?
