I have recently bought a Sony HitBit HB-75. I would like to replace the rifa filter capacitors. However, the little PCB is connected to the voltage converter via several cables, using connectors which i have never seen before and i have no clue how to disconnect them. Does somebody have a hint for me ? Thanks a lot.

Please post a photo, it's not clear what PCB and connectors you mean.

Here is a picture of the connectors on the little PCB with the filter capacitors.

This is so-called "wire wrap": https://en.wikipedia.org/wiki/Wire_wrap

I don't think that you should touch these connections.
