I've partially disassembled the knob unit--
there's a glass/ceramic disc
with radial markings, and with what appears to be an incandescent bulb on
one side and a pair of sensors on the other. The bulb does not appear to
be illuminating when powered up (it does seem to be getting 5V),so this
seems suspect but I don't know whether it's supposed to be emitting
visible light or not. I also don't know what to replace it with.
Anyone repaired one of these before?
I'm guessing Tony'll havesome input here :).
Thanksas always,
Josh
I haven't repaired (or even seen) one, but the limiting factor will be what the
sensors can detect. If you can
get a part number you can look them up and see if you can get a LED that will emit light
of a detectable wavelength.
