Hi there,

Does anyone have a schematic for a MYJG40w power supply? . Have emailed JNMYDY.com but no reply.

I fitted a replacement supply, switched it ON, its went bang and seems to have fried two diodes, an IC and an optocoupler right at the edge of the board at the green terminal block, see pic. Alas this is not a returnable item. The board might be repairable if I have a schematic. The bigger question is why did it go bang and where in the 240v wiring is the central issue.

Any assistance, links etc would be very helpful.
