Stairville Led Bar 240/8 RGB DMX 30°

Outlook and LED's power are fine, but the electronics inside are tragedy. I got my example with not working DMX protocol because of 1. pin of XLR unconnected. When I opened to look for reason and fixed it, the fixture stopped working because of weak LED drivers, which replacing was also very hard, and not beacuse of SMD parts, but because of the fact, that every time I replaced the part, it got destroyed. Finally I fixed that, but I won't forget how hard it was.
