[SOLVED - Not an LCD test fail] Circuit Gem - LCD Test fail?

I have just finished soldering the Circuit Gem to the Raspberry Pi, flashed the SD and tried to boot but it seems that it loops the LCD test, displaying:
---------------------------------------
[Its current Time]
---------------------------------------
GPIO SHDM = [OFF]
TEST LCD..
followed by the test pattern over and over.
I have made a small video of the boot sequence:
And here are two pictures that show the error and test pattern:
Any ideas on what to check/do?

Going through the GPIO list in the FAQ (https://github.com/kiteretro/Circuit-Ge ... it-Gem-FAQ), I think it is GPIO SHDN = [OFF] and not GPIO SHDM = [OFF]. I have tested GPIO 7 to test pad F (PI_SHDN) and there is continuity.

Looks good to me, i need to actually apply a few fixes to the tester app as it currently disables the safe shutdown (when in testing mode only).
If working properly, it should show what you see, and when you slide the switch OFF it will power down instantly.

Yup, sliding the switch to OFF turns it off instantly. So all is good then! Should I just # the testing mode and boot normally?

Yep i've added a note to the wiki about what to expect with testing, luckily the gem is 'simple' and if it boots and shows stuff on screen then that's the hardest part done!

So, when I run this test, it says 'GPIO SHDN = [ON]', not 'OFF'. Is that anything to worry about?
