Update: still nothing yet.
- These diodes, D2001-D2008 all have 22ohms forward and backwards and 0.010V forwards and backwards. This seems odd.
- Leads are positive to the right then leads swapped for other value.

- These two transformers(?) have continuity as well. One in picture and the other on otherside of PDM. Both identical shapes.
Next, otherside of the black capacitors that seem to have components of 1 diode and 2 transistors on each side.

- 0.353V forward and 0L reverse

R3010 and R3016 = continuity, seems odd.
R583 and the equivalent across from it are both = 177.9 kOhms
R581 - can't measure it.

R3023 = 10.14 kOhms
