Hi everyone. Wanted to see if anyone could help before we call a service agent. I'm working at a university over the summer doing some tech cleaning and maintenance and stuff. In one room, we are running a Smartboard on a wall connected to a Mac Mini, Apple TV, Blu-Ray Player, and some other devices. Everything is connected to a Crestron DMPS-100C media switcher. The switcher is connected to the SmartBoard via a powered Ethernet box which then connects through HDMI. The length from the switcher to the box is about 70 feet because of the tall ceilings. Our problem is when we switch inputs then back to the Mac Mini, static fuzz appears and it won't get a signal displaying the image. Any ideas? It worked well for a few years then this started to happen last year.
