I have a colleague which suddenly recieved an error message "E143-4 Home Gateway HNA expired" on his secondary TV during this weekend. He has 2 brand new HD PVRs (not sure whether it is Pace or UEC decoders), single dish with a dual LNB, 2X4 multiswitch and a hearbeat cable in his setup. The PVR in his living room is the primary decoder, and the PVR in his bedroom is the secondary decoder. It is a new setup, having being installed by an accredited installer less than two weeks ago. The call centre just said it must be an installation fault. However, it has been working faultlesly for two weeks, and suddenly over the weekend got this message on the TV in his bedroom.
Any suggestions what to check?
