20D problem

[jjjnettie (Jeanette)]

I recently bought an AC power supply for my Canon 20d.
But the camera doesn't power up with it.
I had the power supply checked out and there's nothing wrong with it.
What am I doing wrong?
Do I have to change settings within the camera before using it?
Or is it the camera?

Sounds familiar.

With my 350D, I also bought an AC power supply and it wouldn't power up until I put the battery compartment door back on, and closed it (I had removed it so I could use a battery grip).

Try that

To close the compartment door, I will need to cut an outlet for the lead. Is that what you had to do?

[Tilt (Michael)]

No cutting required, there is a small section already cut out for the cable to pass through when the door is closed.

The gap for the cable is actually on the body of the camera, not on the door.

Hi JJJ

IF(??) the 20D is like the 40D, here is a crop from the 40D Manual showing how the cord fits into the cord notch. With the normal battery inserted, the cord notch is closed by a rubber insert.

When I insert the mains adapter, this rubber insert “peels” away, although it remains attached and hinged to the body.

Cheers

Yep, that's it, just as Dennis has indicated on the diagram.

Yes, I see now.
I hadn't noticed rubber bit. I thought it was part of the body.
Thank you all very much for your help.
