Word of advice to anyone who is buying the 2.0 kit and planning to keep their WOZ... install the kit sooner than later. Most of you won't want to find out that you have an issue outside of warranty.
I sat on my kit for many months, maybe even a year as the previous 'near full light replacement' was done with the filtered/buffered boards and had been working without any issue. I too order the kit as a back-up for a rainy day. One day it hit me, "what if there are DOA issue(s) with something in the kit?" There are a lot of parts in that kit, boards, cabling, power supply etc...
Long story long, I did the full install and had an issue right away. I contacted support first via email and then by phone and was eventually able to get Butch on the phone and we stepped through a bunch of stuff to try to isolate the problem. It all came down to the main RJ45 pass-thru board having an almost invisible line of solder shorting two solder pads together. Butch narrowed it down to that pcb but was surprised as there really isn't any 'tech' on that board, it's all signal pass-thru. He was going to send one to me but I decided to look at it under a magnifier and found the short. It literally was spiderweb thin.
