What to do if there is no display on the keypad after power up for Bosch Security System?

If your Bosch Security System keypad isn't displaying anything after powering up, it could be due to a failure in the AC power or battery fuses, or abnormal RBGY wiring. Check that the AC power and battery fuses are properly connected and functioning correctly. Also, try reconnecting the RBGY wiring.
