Smarthome ICON Schematics?

[Brian W. Antoine‏]

Anybody ever reverse engineered the schematic for these? I've got a couple
that have failed for reasons other than those cheap button switches, and
I'd like to repair them, if I can trace through the circuit and find the
failed capacitor.

I've got a couple that try to power up, but the led just flashes, like they
got power via a capacitance dropper circuit and the cap has failed.
