EOS 400D / Rebel XTi Digital Camera
EOS 400D/Rebel XTi doesn't have live view function, so you cannot see the picture you are taking.

Had the same problem myself, I purchased a new lcd from ebay (user name: ProphotoSD). He has tons of factory LCD's, cost around 90$. Please note that if you cracked the clear cover above the lcd that is a separate piece however it wont effect the lcd working (this piece is also replaceable). Then I found a simple tutorial for disassembling the camera body on google. Took me like 25 min, very simple job, just need a very small phillips head screw driver. Hope this helps!

There have been several reports of CF cards that work with all cameras, except the Rebel XTi. It depends on the actual manufacturer of the card. Canon made a change mid-production that affected the data saving. Try another brand of card & you should not have that problem any more.

You will be pleased to hear there is nothing wrong with your camera, that's the way it is I'm afraid, there is no live preview on most dSLR's except the most recent, most expensive models..

It took me a while to get used to the idea after using compacts for a few years, but we were quite happy with the viewfinders on our film SLR's...

Happy snappin

DO NOT MESS with a new camera (or any other new equipment).
Take/send it back to the vendor, The purchaser has rights also. Number one it must work.
I don't know your location but in UK (& Europe) we have very strict consumer legislation.
