Flash lamp and turn offusually 1 of the 2 lamps is burnt out, if you can't replace the lamp I will teach you how to turn off the protection of the ci sem2004, it works normally with almost no replace in lightingPlace a 330r resistor on pin 1, a 2k2 resistor on pin 14 and a 1n4148 diode with the cathode connected to pins 10 and 11, then join the 2 remaining ends of the 2 resistors to the diode anodePedro Igor
