I am having trouble identifying a diode that was physically burned by a cooked power supply mosfet. I could not get clear photo of the diodes in the power supply section but it looks exactly like D3 in the photo, no numbers just black on one end and a thin gold stripe. It has .6 voltage drop one way and reads open when I reverse the leads. I was thinking it’s a 4148. Any thoughts?

Maybe, or a Zener diode. Remove the bad one and look for markings.
It will have 4148 on it, if it's a 1N4148.

The damaged one is not readable. I’ll pull one of the good ones and check it for numbers. Thanks !
