The blank screen indicates that the display/control unit isn't receiving power. Check the unit's ground connection to the trailer frame and the power connection to ensure you're getting power to the unit.

The beeping indicates that the system needs to be reset/recalibrated.

I'd begin by checking the fuses in the control unit and replace if needed. Then, remove the control unit from power for a couple of minutes, then reattach which allows the unit to reset.

Then, proceed to reset the zero point, as outlined in the owner's manual (I'll provide the procedure below as well).

1. Turn “ON/OFF” button “OFF”.
2. Push “FRONT” button 10 times.
3. Push “REAR” button 10 times.
4. Control will flash and beep, LCD says “ZERO POINT CALIBRATE”.
5. Manually operate the jacks to attain unit level condition (use carpenter’s level).
6. To memorize this level condition , press “ENTER”.
7. LCD says “ZERO POINT STABILITY SUCCESSFULLY SET”.
8. The control will then turn off.
9. Turn “ON/OFF” on to commence operation.
