Take some resistance readings on the data pad to gnd pad and see what values you have. Did the pixel just quit working as in no glowing. Was this just one bad unit? Mine was fine until the first rain and all kinds of problems occurred. They would start coming on when no signal was applied. I would take them down and let them dry out and some of them would come back to life. I had some failure due to the injection mold process. It actually pushed the pcb at an angle. The pixels would still work except missing colors. Here is the link to my Photobucket bad pixel library http://s577.photobucket.com/user/Hauvega/slideshow/Pixel%20problems
My c9 covers had moisture in them with some of them having a few drops of water. All my pixels had power applied to them. My pixels have the ws2811s chips in them. I believe the ws2811b series are the problematic ones.
The new pcb redesign helps in putting the gnd line in the middle of the power and data line. This should solve the damage to the chip data input and output. If moisture can still get into the pixel, damage is going to take longer. Need a year of testing by exposing to the elements and disassembly of pixels to see if any ingress has occurred.

Thanks for the link Hauvega, you definitely had a lot of damage to your pixels pcb.
My lights starting doing there own thing like turning themselves on and not responding to the controller at all while others worked fine within the same string. This was after leaving the power on over night but it was a cold and dry night so I do not think water was my issue. The failures were to quick so it must of been the batch of defective chips as Ray advised me. I will check the resistance to see what readings I have as you recommend.
So far I have not had any bad pixels testing the new lights but they are in my home. Saying that they would get much warmer in the house so I think the defective chip issue is definitely resolved. Maybe the overheated chip made the plastic expand and let water in where the led reflector is?? I guess time will tell all if this helps with any water problems. I hope all will be well as I really like the overall Technicolor pixel design compared to the others!
