I have an occasional recurring problem with TDL sets flashing and going out of service on a Magix. I replaced a board once and it made no difference. Once I fixed it by reseating the amphenol (sp?) cable. Sometimes the customer fixes it by turning the system on and off a couple of times. The customer has 2 TDL boards, and I fixed the problem for about 6 months by swapping them. Now it is back. Has anyone had this happen? There are no errors in the error log, and no one is near the equipment when this happens. I am wondering what to replace next??? Thanks!
