Camera stuck on AUTO setting

I recently replaced the top lcd, rear lcd and after not being able to solve this issue, I then replaced the entire top section of the camera.

The fault lies with the camera working perfectly fine, however it only works in AUTO mode. No matter what I turn the dial to it wont go into M,A,S or P or scene, U1 or U2 or no flash.

Factory reset has been done, firmware is the latest too.

Any ideas?
