On the power supply board, check all electrolytic capacitors for capacitance and ESR. Check all resistors, diodes, and transistors. Once you're sure all components on the power supply board are functional, you can move on to the B365N. Check all components on the B365N for functionality. Replace faulty components according to the following list: 433...

Hello guys, Have you managed to fix the controller? Have you found out what for diode is used there? I also have the WLGN 22 E and my 'automatic' regime ceased working. My resistor is burned to ashes, one of transistors is cracked and so is probably the diode. I haven't done any measurement yet, but I'd like to replace the other transistor as well....
hi mate ive been looking into these switch mode psu chargers,! had quite a few to fix here in my workshop. i can tell you that burning out the uc3842 is caused by faulty capacitor next to uc3842 --35v 100uf 105c, but needs to be replaced, also check diode next to capacitor ,i would also use a 11N90 TRANSISTOR WHEN REPLACING THE 2SK1341 THIS IS MUCH...
Hi. Thanks for this info. That helps me heaps in getting my broken pcb fixed. Besides the transistor you described, I think the transformer on position T1 is also faulty on my board (marked as E47 X 0948). Does somebody know what type I replace this with. Thanks
