Hi
I'm having a weird problem with my Placid HD BP. I checked my soldering and component placement but I can't figure out why RD2B is not lit on the negative side. The other two LEDs are lit. I measured the voltage on TP_VREF- and i'm getting -10.80V or so. That's obviously wrong.
I'm sure my transistors are in the right place. I checked that several times.
What could be the problem?

Found the problem.. the LED was bad. Swapped it out for a new LED and it works fine.

I checked the orientation of the LEDs and they were all fine. Somehow this one was a dud.
I swapped one with a different forward voltage (1.6V) though. Seems to work fine.
