/diy/ - Do It Yourself

>>2490078
Okay made some progress but still need some help,
I’m reading 0V across the right channel where there should be 18V, marked in red. So it could be a bad diode. Interesting that on the schematic they’re listed as the same part # for d2 d3, but on the board they are two different pieces.
My question is how do I measure the area on the right, what are the black bars, transformer? I want to see how far back the problem is
