I have a megatouch Crown that had monitor issues a while back (only jumbled colors displayed but the touch screen still worked). After leaving it sit for a few months I started it up again and now I am getting an invalid key error message (screen is now working again)?!? How do I fix/troubleshoot this?

Thanks!
 
I had this same issue a while back. I had an intermittent "invalid key" message. Some days the machine would boot with no issues. I'd try again later and I'd get the invalid key. I just had to find the sweet spot for the key to be in and I haven't had the message in months. Try repositioning the key, or removing and reinstalling it. Clean both sides and make sure it's seated correctly.

If none of that helps, try cleaning the edge connections on the boards.
