PCB to scheme.

Hi!
I’m trying to understand and simulate a Power Supply. Wiring is very clear for me. But the PCB’s aren’t.
Is there a way to reverse engineer a PCB and obtain its diagram/scheme?
The first piece I want to describe is this:

Take a picture of the track side, print it out then draw the components on it.
From there it's much easier to start drawing out the schematic

At least it is a one-sided board. The problem with power supplies and several-model electronics is that they make a master PCB with all the features, then fabricate that one, and for lower-tier models they remove some of the sub-systems.
The advice above is pretty solid, but take into account not all component hoels are populated... and probably there is a good portion of traces shorted to ground. I would start from there, use te continuity meter and start checking which ones are shorted, where do the "0 ohm" go and so on.

Here are some different views of your board that might be helpful.
