First year here, I'm just getting totally random failures every day practically. It's a bit of a pain to basically spend $2 replacing 2 pixels a night (cost of connectors and replacement pixel). I only have ~1300 pixels up but next year I will probably triple it. I will purchase my pixels a few months earlier next year and will look to burn them in for a while but based on what has happened this year I don't think that will eliminate everything as some are failing into the 3rd week of operation. My biggest annoyance is if I forget to check the pixels before the show starts I have only a short time period to be fixing pixels before it gets too dark and getting on the roof at night isn't high on my priority list.
