Why is the keypad on the unit totally blank and not on while have good line voltage to drive?

Need to 1st verify that the keypad is plugged in securely and control supply is sufficient on CL1 & CL2. If keypad is remotely mounted and not directly on the main control board then need to verify remote cable and try to install driectly onto drive and see if issue is corrected. Also, if possible may want to try another keypad if one is readily accessible to isolate the issue. If concern does not appear to be keypad then check the main control board connections and check keypad power supply on J9 connection coming from the power boad which should be +5v from terminal 8 to 7 (-) {terminal location 6 having no wire connected as reference point}.
