I wanted it back ASAP, so I just ordered a replacement board, and it's a happy ending at least for now.

But when I was consuming the first fix... I mean cup in a while, I realized that I had a couple of questions which either required me to open the blasted thing up again (no chance in hell), or to just ask the community. Please forgive me for being Google-impaired, but I tried. Honest.

Does anyone know (for BV1980_TRIAC_BOARD RPBBV198040):

• What is that Zener diode marked ZD1?
• What components do people use to replace optocouplers and triacs? The originals seem to be obsolete and out of stock everywhere...
