Successfully Repaired A Dead Hover Board Charger
A guy next door brought me this hover board charger for repair. He also brought the hover board itself so I can test it when I am done with the repair. I powered on the device though a current limiter and the power indicator did not light up to show any kind of life in it so I took it apart for testing.
I cut the plastic open and revealed what inside this cheap Chinese made board.
The quality of this board is just bad but the customer wanted it repaired so let us begin.
The first thing I saw was this blown fuse and not just blown but broken in half and common sense is when the main fuse is blown, always check the bridge rectifier and sure enough it was shorted as well.
It was shorted on all its pins and needed a replacement; the part number is KBP310 and I think I have the exact replacement for this part.
I also found the Mosfet shorted as well; part number 8N60C.

On the same line of the Mosfet, I found an SMD resistor open and the part number is 1R00 which is one ohm fuse resistor and it was time to replace all these blown parts and test the charger.
The charger was alive again and since the customer brought the hover board to be tested
I connected it to the charger and the stand by light should switch to red to indicate it is charger and…

You have explained as though it was very easy, but we all know how much expertise is required to troubleshoot like this! Excellent! Many thanks for sharing, dear friend!

Cheaply manufactured design or not doesn't matter for a pro like you! Maybe next time you also could show or mention the output voltage or a label or marking of the fixed model power adapter you fixed?

Albert: thanks man.
usually the output voltage on these charger is 42 DC volts but there was no brand name on it to show. I usually mention that in my articles but this time there was nothing to share about that. have a blessed day

I thought power ic on smps is also usually affected when fuse is blown, but in ur case it seems to be intact. thanks for sharing.
