I am completely new at this. I have a canon digital rebel xti and it has some broken prongs in the cf reader slot. However im trying to see if it is worth fixing or just replacing the camera entirely as it is a older one. I have charged 2 batteries and tried turning it on without a memory card and it wont, my question is shouldnt it be able to turn on without the memory card? If so what could I be doing wrong or what else can I try?

No it is not. Cut your lose and buy a new Rebel. Besides not being worth fixing the new Rebels are lightyears better than an XTi. That alone is reason enough to replace it even if it was working.
