Hi folks got.a cannon eos 350d the problem I have is the cf button is continually flashing is this normal or have I a problem the cf.card is brand new

What you require is to format the Compact Flash Card. The CF card should be formatted when new and after every download. Format the card in the camera it is going to be used it. Constantly deleting pictures on the memory card will cause major corruptions and total failure. Formatting cleans the memory and allows the camera to communicate properly with the CF Card.
I going to give you several diagrams on where to go in your camera to format. these diagrams are screen shots right from your manual.

Have you tried inserting the card while pressing the remove button at the same time?

Joe, this happened to me, just tonight... I got a new CF card and stuck it in, turned it on and one CF card flash. Completely dead from there. I found one of the CF card pins bent over, shorted out the socket and blew the mainboard fuse. I took the camera apart, found the fuse (labelled K) about under the set button area) I bridged the fuse with a bit of solder, straightened out the pin in the socket, put it all back together and it's working fine. The fuse is under the right side shield cover, it's labelled with a letter K. There is another fuse on the power inlet board (below the shutter button) and it's labelled 'P'...

Check the pins in the card slot that non are bent. Other than that it means a return to Canon.

Instead of connecting via the camera, just use a USB card reader and put the CF card in that.

It sounds like you have some bent pins in the card slot. Take it to a reputable camera repair and they can look and tell you for sure.

I don't have a 350D, and don't have a list of codes but I would guess the error code refers to the Compact Flash card. In the instructions to my camera, a 400D, the solution is to remove and reinstall the card, if there is still a problem, you might have to format the card. Hopefully this will help!

the best way is contact cannon for a repair shoip or sevice center near you at www.cannon.com , choose your country and send them a email or call them

good luck

check all the pins in the CF socket in the camera are there, or are not bent, repair is expensive if broken

I'm afraid they break most of the time. You can try it though since the repair involves replacing the board that the connector is soldered to, $$$
