Hi, I have a 210 and all it is doing is showing 2 jpgs that fade into each other. That's all it's doing. I used BrightAuthor to create the presentation and I am just using an SD card to update when I need to (no networking involved.) I had tested the unit here in my shop for a few days and it ran 24/7 with no problems at all. I installed the unit 3 days ago and every day since it has been installed the screen will go black and stay that way until the 210 is unplugged and plugged back in. I can't bother my customer to have to do this every day. It it happens at different times of day every day so I can't figure out a pattern. Can anyone tell me what the first step of figuring out what is wrong? I assume that it's something that I did I just don't know how to check it.
