Can a faulty CompactFlash card damage a camera's card slot?

I inserted a damaged CompactFlash card into my Canon EOS 350D, and afterward the camera only displayed “no CF” on the LCD and would not respond to buttons or show any card-access activity. I removed the card, batteries, and lens, and also tried another CF card that is known to work, but the camera still behaves the same way.
The damaged card may have been short-circuited earlier when I inserted it into a card reader while it was still humid; the reader became very hot immediately.
Can a bad CF card damage the camera, and is there anything else worth trying before repair?

If you have removed the card from the camera and put a new one in (that is known to be good) then it sounds like you already have your answer.
It is possible that the card (rather than the reader) was shorted out and that it damaged the reader both on the computer and in the camera. If that is the case, then there is a good chance you need to have the card reader and possibly system board replaced in the camera.
Your best bet is probably to contact Canon to see about what a repair would cost and either send it in for service or buy a new (or used) camera since the 350D is now pretty old and may well not be worth repairing.

Yes. A faulty or shorted CompactFlash card can potentially damage a camera’s card interface. Since the camera still shows “no CF” and remains unresponsive even after removing power and trying a known-good card, the problem is likely no longer the card itself but damage to the camera’s CF reader circuitry, and possibly the main board.
At that point, there usually isn’t much else to try beyond the basic steps you already did. The practical next step is service: contact Canon or a camera repair shop for an estimate. Because the EOS 350D is an older model, repair may cost more than the camera is worth, so replacing it with another used or newer body may make more sense.
