LED panel malfunction | I did all the testing procedures, I changed the mp4010 control pwm ci, I changed the smd coupling capacitors of the circuit and nothing resolved it, I went to check the smd resistors of the circuit, to my surprise I found a resistor that had not been changed but had a mounting error on the pci. presented with value (1k) but in the service manual the value is (10k) I replaced it following the service manual and it worked perfectly | Resistor in position rb16 on the pci value of (1k) in the service manual value of (10k), this blessed component is next to the smd capacitor cb5 on the fb line of the control pwm circuit | RUBERTAN |
