Hi colbee53, welcome to the Sony Forums 
If neither touching the DISP/BATTINFO button nor calibration work you should try a reset: see p.63 of the manual. If the control buttons still don't appear it could be a malfunction, possibly an issue with the ribbon connector between camera body and screen.
An electronics repair shop may be able to help, or you could ask for advice from Sony customer service (details on this sticky)
Cheers
Mick
