@Retroshire: Quartz is again a tip that didn't work.  What have you replaced so far? Everything except the PCB and the filters. I also thought about these filters; but I remembered that they are also plain ferrites, like in plus/4. (What could be wrong with them? If they are just not the right value...) But in C16 these are LC filters (EM3/4/5), not just ferrites, as you can see in the picture from MMS. After all that sucking  I would replace them with a short circuit as a test. (Of course, I would short the in+out, the GND is not connected.)
@Hifi: Sajnos 2021-ben ezekhez nem nagyon találsz szakembert a közeledben. Így sokszor marad a "csináld magad" mozgalom!
