From what you are indicating the chip is functioning - but you are having some intermittent problem with it. The chips either work or do not (usually). I wonder if it is fully seated. Can you compare it to the LM which is not causing you this type of problem? Let me know if it is slightly higher or askew, and whether you can press it more fully seated or not. I can send you a replacement chip/holder...but I want to make sure that corrects the problem and it is not an issue pertaining to fitment.
