Roadhog 3 touchscreen issues

I've recently started losing one or both of the screens on our Roadhog. They periodically go dark and stay dark for up to 5 minutes. Sometimes it's just one, but sometimes both. I'm going to open it up and check that the connections are seated, but yesterday I lost both of them and it displayed an "out of range" message. Has anyone experienced this or have an idea what that might mean?
