Looking for a schematic for this machine.
Board model BYG40 NM-A411

I have a faulty diode (PD7) and I am trying to figure out what to replace it with.

Thank you in advance

Hi. See attached.

PD7 = DFLZ5V6 (Diodes Inc.)

It is a common 5v6 rated volt zener diode. From where do you prefer to source your parts ? There are many replacements to this component in the market.

I got a motherboard with exactly the same fualt, PD7 is blowen and shorted to the graound!!, when i removed it the short circut was gone but when i connected the power to the motherboard the capacitor next to this diod blowed, Would like to know it there is a supllier for such parts in main England, usully i order from aliexpress but it's a long waiting, i have a lot of motherboards that i can remove parts from theme, but i don't reelly know witch capacitor i need,
It's basicly a tantalum capacitor, the most capacitors on this circuit are N8 d m, But i can't fint the datasheet for this capacitor or where to buy the capacitor it self,
Thanks for any help
