1488 won't white balance and goes dark after 3 minutes
It seems like something overheats inside your consoles or the heads. I would start with troubleshooting the issues with airflowing the units. Try also quick cross connecting the hot head or console with the other cold ones. That might give you an idea of what is out of order either the Head or the Console.
The problem seems to be with the console , one of the internal board/card problem. The exact problem can be assessed over a Zoom call and I will be glad to help by providing instructions over a video call.
