I'll Have to look at the layout but maybe C16 was backwards? I've switched to all ceramic caps and that one was polarized...but glad you got that fixed for now :)

Yeah, just looked at the layout; C16 was backwards. You're lucky it didn't blow up; tantalum caps HATE reverse polarity.

Don't use polarized caps. I intentionally left off polarity markings on all caps because I used ceramics.
