Yes, probably the display module uP clock is not running at
close enough to the correct frequency to receive
the communications properly (or some other problem).
So, you can try to keep it warmer, or we can try another
display module, which MIGHT work better.
Did you build this as a kit?
What color is the LED Display?
If you have the mechanical skills to replace the display
module, I can sell an original type display module to you,
with the three wires already soldered on.
Last I checked, http://www.sparkfun.com
no longer makes this
module (COM-09765) , and their "replacement" module ( COM-11442)
requires a one-byte firmware change, because it is not perfectly
compatible (apparently due to an oversight).
Or, you can send it to me to replace the display for you, which
would be a bit more expensive, and require shipping two ways.
PM me your address and phone number (if in the USA)
and I will call you with/for details.
Yes, very frustrating, I know!
