[Elecraft] K3S: LCD backlight is on, but no segments are lit

[Christopher Hoover]

Replacement part is:

C37,102    10 uF,10V,20%,CERM,0805,SMD       E530223      Panasonic
ECJ-2FF1A106Z    Digikey    PCC2233TR-ND        PCC2233CT-ND

This is Y5V dielectric.

It looks easy to get a 16V part in 0805 (and X5R at that).

I've bodged in a 10u 10V Y5V 1206 for the time being.
