Dead 40D - no power

My BIL just called me and said his 40D is dead

It was working fine last week. He put it away and now it's dead. He took off the grip and just inserted the battery in and still no power. Tried both batteries and AA same thing.

Any other suggestions?

ummm trying putting the battery back into the charger for a few seconds hopfully the battery is just shocked putting it in the charge fix it.

also make sure the battery is full or at least charged. and take off the grip first and try without

Bah... don't bother. It's a dead 40D. Happens pretty often. It happened to me. It's a faulty DC-DC circuit board. 1D3's has this part as well and is known to kill the body as you explained. Send it in.

Yup, it's dead alright. Talked to Canon tech and he said send it in.

I feel bad that it happened right at the holidays
