Do not think that the argon filled bag is easy. They are impossible to seal properly and always need refilling.

Regarding the blue pixel mess, I can think of two things:
1. The condensation on the circuit board can cause shorts and can cause electronics damage or camera crashing. This is my guess what happened.
2. Thermal contraction/expansion - don't let the camera cool down/warm up too fast.
Thank you to both glen and yourself for your insights. As much as I can see how the argon filling would work and how impressed I am of the lengths that you guys went to in your experimentation, I donít think itís an avenue I will attempt as I can understand how hard it would be to achieve.

What I think I will do though is attempt to reduce moisture as much as possible starting first with setting my cold finger above the dew point referencing from the link you sent me.

Thank you both again for your help. I really appreciate it.
