Heie is a poster boy for how tough Pentax cameras are! Abusing his cameras to explore the limits so we mortals can rest assured our cameras will survive our more sedate lives.

On a microscopic scale, you cracked the LCD at sub-zero temperatures.
Now that the camera is warmer, the cracks are gone because the LCD is warmed up and the cracks have expanded.

If you take your camera and put it in the freezer, my guess is the "damage" will return.

There are no "miracles" just unknown science.

My $.02

hm... seem logical, but if the cracks expanded in warmer temp, it will be more visible. :P

Not necessarily.

When the LCD/glass was cold, on a molecular level, the area was smaller because it *was* smaller. When the glass broke, it broke at that temperature and dimension(s).
As soon as the glass warmed, it expanded into the cracks, and they disappeared.

Since there is probably some substrate that holds the entire assembly together to deal with expansion and contracting, it appears that everything is fine, but it's probably not.

Note to self, don't buy Heie's camera if I see it on sale in the marketplace.

Actually I already had a note not to do that because I know that you are the guy who puts pentax gear through the test of fire (and water and dirt and mud and snow and every other thing) but we all love you even more for it.

Ricoh Imaging should buy it and put it into a museum. With a description of every abuse it went through (and demonstrations that it still works).

Due to all the free publicity you gave Pentax, they sent you a magical camera

Also to note that LCD after a certain temperature turn black. It might be a cold pattern exacerbated by the hairline cracks.

I am such a klutz that I fit my equipment with the Delkin metal shades. They also gives a bit of light protection trying to read the screen in sunlight by shading it. The shade part snaps on and off when working indoors when I have the camera on a tripod and know that neither I nor the local rug rats aren't going to hit the LCD with anything.

That is truly fascinating.

I remember reading an article a couple years back about Infinity and higher end Nissans being painted with a self healing paint. That way when you get unnecessary door dings and rock chips, it will heal over the primer. Like a creepy new skin.

But the Science is known

The pressure from the impact forced the liquid crystal through the coulour filter substrate leaving a splodge of liquid trapped between the polariser and filter

Given time this drains back betwen the electrode and filter (where it shoudl be)



An explanation of LCD Panel Technology

There never was any cracked screen so no miracle.

Well regardless of the explanation, I can confirm that the K-5 IIs is 100% good as new despite the horror of how it looked originally
