Why doesn't my charger work?

  • The charger for my Ryobi One plus BCL14181H doesn't work. I took to pieces it and saw that one of resistance and transistor were burned. I replaced the resistance, but i can't see the number of transistor. It would be good if someone makes photos of sceme and of transistor and writes the number of this transistor.

Attempting to fix this type of equipment is dangerous, and even deadly. A typical power supply contains capacitors large enough to deliver a significant electrical shock. Any mistakes in resoldering this could result in bad things. You can find out about why here: Device Safety.

Thank you for comment. I know safety rules. I think i waited enough time to discharge capacitors.

I have the same problem, I have 4 chargers with the same part as yours burned, was your repair successful

put a small alli heatsink on it witha bit of silicon when this mosfet goes short it also shorts one of the avalanch diodes two there side by side it can also blow the driver for the switchmode power transformer and also the load resistor along side it . The parts are available on the net

Hello,

My Ryobi Charger Board has problem as below:

- The Diode MBR5200 was short circuit

- The Mosfet Mosfet 9565bgh was burned

- The Zener Diode ZD2 which is closed the Mosfet 9565bgh was burned.

I have replaced the Diode MBR5200 and the Mosfet 9565bgh, but I did not know what is the Zener Diode ZD2 (Regulated Voltage = ?)

Please advise with thanks,

Anh Le
