iPad 3 is not recognized by iTunes

I have gone through the Apple support website which has instructed me to do many things like try different USB ports to unstall and update iTunes, even install updated drivers. However, nothing has work up to this point. The advice that I am looking for now is (1) am I missing something obvious here? (2) Do I need to send it in for repair or something?

Thanks
