I have the problem, that I had a short moment where I was not paying attention and measured a 230V AC over a wrong connection and seem to grilled only the oscillation.
The normal measurements are still working correctly, at a visual inspection the only SMD part which seems damaged is the component D11 at the board HDS200-MAIN-V3.1.
I cannot see which part this is, so I can replace it (no visual, no wiring diagram and no PCB info). Hopefully someone here can help me with this, I do not want to buy a new one, when the repair cost would be only cents.
