Hey,

So this is what happened.

My 350D worked fine all day long, then i went on to try my cf card in an card reader.

After i put it back in ( I couldnt get it first because i didnt know how to put it so, i might have bend the pins.. but i dk if thats the problem) then after i tried everything new batteries battery grip off, that 10 minute wait and remove batteries and all! It still didn't work!!

What do i have to do please help me

I'm afraid it does sound like you have bent some of the pins in the CF slot. The best way to find out is to pop the card out and with a penlight look down the slot, it will be fairly obvious if any are.

The problem comes because the design of the compact flash interface puts the power and ground pins close to each other and compounds it by making the longer than the surrounding pins so it's easier for them to get bent. If power and ground short then it usually takes out the main board. This give the symptoms you seem to be seeing. The only repair is replacement of the whole main board. I'm afraid it's going to be cheaper to get hold of a second hand 500D or 550D as a replacement/upgrade.

Sorry I can't be more helpful

Ian
