Anyway, the fact that you are getting the power voltage on your output tells me it's shorted somewhere....and as Brian says..you should be getting 23V+ on CPUMP(36).
It's no coincidence that CPUMP is supplied through VDDA and C9...very close to C10...so look closely for shorting.

After some probing around, C16 and C18 seem to be shorted out.
