I am a total beginner at photography and wanted to start dSLR with a basic camera but after having it only a few days, it stopped powering on. I removed and changed the CF card, still no power. I continued by removing the lens, cleaning connectors, replacing battery, still no power EXCEPT the lcd screen will show the EOS in the top left when it's turned on with a CF card in place. With no CF card in place, the camera powers up like normal but the lcd reads "No CF Card".

I have checked the pins and they are all there and none are bent (as best as I can tell), I've cleaned the contacts and tried 3 different CF cards.

It worked perfect for the first few days and now this...I'm so distressed.

Does anyone have a clue what could be wrong? I could sure use some help.

Thanks in advance.
