Hey Guys,
I just read through this thread and thought I would add my experience to the post should any of you be interested
I had the same problem approximately every month when I first purchased the board. I was going inside pulliing and pushing all the ribbon cables into place, at least the ones I could get my hands onto every 4-5 weeks. About two months ago I did something a little different. I actually removed all the big ribbon connectors including the ones right at the back where the large power cable connects to, and decided to tap the sides with a small headed hammer to force the female pins inside them to close firmlybor tighten within the connector. I did this because at the time the D8B was open, the glue I ordered hadn't arrived yet. I know this may seem an unauthordox method, but since replacing them snuggly, the board hasn't played up once. The glue arrived a couple of days latter and I still haven't used it on either of my D8Bs, that's not to say that I won't some day in the future, but up until now it hasn't been needed. In my case I believe expansion and contraction due to heat and cold playing its part in the studio may be the culprit, but I'm monitoring the issue and hopefully things remain as they are
