Hello!
I learned a lot the last weeks about repairing and how power supplies are structured. Fixed two TVs (even though it wasnt really hard since one was a backlight and the other a ribbon tape trick fix).
Let's say I got a basis of knowledge from where I can start to repair easy projects.
Looking on local online markets, there are sometimes faulty devices for free. But where to start?

So i tried asking for a schematic from the company and they would not give me one. Instead they...
