I started the night by cutting the 1/4" out out of the panel rib so that the 4500 will fit. I re-installed the 4500 and powered everything up. Shortly later, the right 4500 went screwy and ended up with two white bars. I power cycled the unit multiple time to no avail.
I sent a text to Geoff Combs telling him about my problems. He happened to be having dinner with the AFS gang at SnF. Unfortunately, when I powered the screens up again, they all worked fine. I generated a system log and mailed it off the Ken at AFS. I'm looking forward to what he sees in the logs.
I did start to configure the left 4500, but this video problem distracted me and I didn't get much done this evening.
The right screen with the two white bars is the problem unit
