1) Please exchange batterires for a new ones. 2) Tight the flexible cables from keypane vs display board. 3)Tight the connector from display board vs lower board(Main motor board) 4)Adjust the reed sensor switch by 1/8" or 3mmsSee the diagram attached. 5)Measure input voltage for 115 Vac to input of main motor board 6) Measure input for power supply for +5VDC to main motor board. 7)Measure output voltage for +5vdc to Display board. 8) Finally see the block diagram that I am attached that I did for people like you. For easy diagnostic and troubleshooting. Sincerely. Merry Christmas. Ernesto CuaddraManagua, Nicaragua.
