Firstly - this is a dead output CCHD (it simply sits high and has no oscillation). I thought others would be interested in a recent CCHD internals and if it would be possible to replace anything busted internally.
It looks like there's a voltage regulation and SOT23-5 device for the output (dual mosfet or Schmitt trigger?), next up to look at what may have gone pop.

Yup, no output on the crystal unfortunately (I have a new one so this is scrap). However it was interesting there's a SOT output device that has both Schmitt triggers and a buffer for driving mosfets - I'm wondering if that device is used on the output.
