Is there any case law where the trial court turned its back to defense expert during his testimony?

If such an ambiguous judicial slight is perceived by counsel, a more timely complaint than was made here is required. So too is a request for a curative admonition. (People v. Franklin (1976) 56 Cal.App.3d 18, 24, 128 Cal.Rptr. 94 [Trial court turned its back to defense expert witness during his testimony. No curative admonition requested. No prejudicial error.].) As in People v. Franklin, the trial court instructed the jury: "I have not intended by anything I have ... done ... to intimate or suggest what you should [7 Cal.App.4th 853] find to be the facts, or that I believe or disbelieve any witness. [p] If anything I have done ... has seemed to so indicate, you will disregard it and form your own conclusion."

Appellant's contention is not well taken.
