I have an HD anywhere 4x4 1080p matrix and am having some problems with getting my sky signal distributed since the weekend. It’s been working fine without interruption for about 4 years but over the weekend I lost signal to both screens it’s connected to (over Cat5e). I’ve eliminated the problem as being the sky signal (having connected a screen directly to the sky box via HDMI in the comms cabinet and getting a perfect picture). I've also eliminated the cable having put a cable tester on the ends of the cable and all works well. I’ve also shut the matrix down, left it for 15 mins and then turned it all back on again without success. I can only think there is an issue with the matrix. Anything else i could check? I’ve got a support ticket in with them at the moment but thought I’d check with all the experts here before i hopefully hear from them in the morning.
