Hello there,
Can someone please help me to repair my charger?
When I switch on, the charger flash the spark and not charging anymore.
And I got the burnt smell.
After open the charger, I don't see any physical damage or burnt mark on circuit board.
I took out all 3 capacitors and tested with meter and all are in good condition.
And diodes too.
I measure the output voltage and voltage is around 1 volt in ON & OFF, ON & OFF, ON & OFF ....... condition.
which is causing that and how to repair?
I'm not good at electronics.
So please bear with me and guide me step by step.
