7D fried!

A friend of me fried his 7D

He was shooting with strobes and some kind of wireless triggers.
He got a 01 error code and the smell of burnt electronics filled the studio.

I asked for more info but he haven't been ready to answer me....
He just sent in his 11 month old camera to repair....

Anyone else that this have happened to?

Sucks for your friend. I wonder what triggers he was using. Problem caused by the trigger.

wireless trigger fries his camera?
huh what kind of trigger

That was the first thing I asked him about, but he didn't answer....

Probably some cheap crap! But I have to check it out

They could fry your camera if they put out too high of a voltage. It's the same thing with old flashes.

Ever since the 20D or somewhere around there, the cameras have been able to withstand 250V trigger voltage. I find it hard to believe a wireless trigger that runs on batteries would generate that much voltage. Something else caused the damage...

Disposable cameras running a a 1.5v AA charge a 110v capacitor. If you don't believe me, take one apart and short it out with your finger. It hurts.

That wasn't John's point. Sure, our cameras' 8 volt batteries supply an oscillator that charges the flash to 500 volts or so. And our off-camera flashes probably have a higher voltage than that.

But our current DSLRs aren't going to be damaged by the trigger voltage supplied by any normal flash or trigger.

I imagine there are ancient industrial strobes that apply more than 250 volts to the camera, but that's not the issue here.

John is right: it's something else.

A lot!

What led you to this discovery?

1st time? Taking a disposable camera apart incorrectly. 2nd time? Thinking removing the battery would help. 3rd-nth time? Dares.

A normal one, no. What about a malfunctioning one? I suppose it could be a coincidence and it was actually the camera that malfunctioned and burnt itself up. It's all just conjecture though.

It also depends upon how the trigger is connected.
Canon specifies the sync connector to withstand 250V, but the hot shoe is often rated 6V, and that's a big difference.
