Hello everyone. Here is my bedside lamp which has some problems, when I turn it on, it turns on just for a moment and then goes off. Which component in its circuit is probably causing this? Is it one of those 3 LEDs or that capacitor or one of those resistors?
Wow , the soldering looks bad. Did you did anything? Do you have a multimeter? If so, since it has minimal components, you can actually test quick, test the LED Test the resistance of the resistor. Looking at the LED, i doubt it is bad, it seems that there are bad solder in place.
I would suggest you to resolder those cold / bad solder joints first.
