Just to be clear I do not have a 976. My processors are as listed in my profile. Does this issue occur with other devices. Is it possible the 976 can't "see" the Firestick when it initially starts up but once it is up it responds correctly. You may have to insert a time delay into the programming to allow the 976 to get hold of the firestick after it starts. It could also be the order in which the system is starting. You can change the order such that the 976 starts first followed by a time delay and then the display. Hope this helps.
