Problem with rotary selector (CDJ 850)

Hello everybody,

one of my CDJs has the problem which has already been described a few times. If I'm using the rotary selector, the list skips 2, 3 or 5 songs back or forward.

I don't want to spend 250-300€ for the whole sparepart (DFLB Assy DWX3152).

Do you know a DIY solution? Maybe a cold solder joint to fix? Or replace the rotary search part (YSD5019)?

Best regards :-)

Edit: YSD5019 or CSD1153. Which one is better?
