Box No Display AC power off Check if 3 thread coupling connector is loosen Check if 3 thread coupling connector is cutting off
No input signal Check the green lamp of the receiving card, if not flash 1£®Check if 3 thread coupling connector is 2£®Check if 9 thread network cables are open or short. 3£®Check if the power of receiving cards is 5V. If all checks are correct, please change the receiving card
Module No Display Module Voltage The voltage is 5V
Signal cable between boxes is open Change the signal cable
HC245 not working Change HC245
Half Module No Display Half module signal Check CP¡¢SC¡¢CT signals
Dark part signal Check the first TB62726's pin 2
Module out of Control CP¡¢SC signal is open or short Check the control signal between the input of the module and HC245; Check the control signal between HC245 and the output of the previous module(CP,SC)
HC245 not work Change HC245
Half Module Out of Control The next module works normally, the SC signal of this module is open or short. Check if the signal between SC and HC245 is open, or it is shorted by other signals
The same part of next module is out of control, the CP signal of this module id open or short. Check if the circuit between CP signal of this module and HC245 is open or shorted by other signals
Module 4*4 Matrix No Display The circuit between TB62726's pin 23 and the external resistor is open. Weld the pin 23 and the resistor again
TB62726's pin 22 is a rosin joint or a open circuit. Weld pin 22 again or use wire jumper to connect the open circuit
Module 4*4 Matrix Dark TB62726's pin 1 is a rosin joint or a open circuit. Weld pin 1 again or use wire jumper to connect the open circuit
TB62726's pin 24 is rosin joint or an open circuit. Weld pin 24 again or use wire jumper to connect the open circuit
Shadow When Display Texts CT signal Check circuits between CT and HC14 and HC138
Dots Out of Control LED doesn't work Change LED lamps
Rosin joint Weld again£»Check correlative TB62726's output pin, Weld again if necessary
Short circuit Cut off the short circuit
Open circuit Connect circuit with wire jumpers
Constant lighting Cathode of LED is short to ground, Change TP62726
