Murray,
Those diffuser leads should just touch the top of the board since 2
spacers are 1/8 inch and the leads are also 1/8 inch. Solder them from
the top of the board - being careful so the iron does not touch anything
but the leads and the solder pads.
If the leads do not touch the solder pads, sand down a spacer so that it
does just touch. If there are rough spots on the spacers, sand them off.

I've been busy. But I'm having fun now!
I have the K2 Owner's Manual Revision G, May 29, 2007. I also have
Errata sheet Rev. G-1, Dec. 12, 2007.
In the Front Panel section, page 27, the original instruction advises to
use two spacers at each end when installing the LCD backlight diffuser
to keep the diffuser exactly 1/8" above the PC board. The Errata sheet
clarifies to use the spacers but remove them after soldering the
diffuser into place.
The issue is that the two spacers are 1/8" thick. The diffuser leads are
exactly 1/8" long. This means with the spacers in place, the diffuser
leads don't actually reach the solder holes. The lead ends are suspended
just above the holes. If I actually manage to line everything up and use
rubber bands to hold all in place while I solder (good luck!), the
solder would need to bridge up to the ends of the diffuser leads for the
soldered connections to hold. This doesn't seem like a good practice.
Is there a newer errata sheet? Or am I not understanding this correctly?
