Yes, I have some C# scripts.

All of my scripts are simple ValueChange calls to update tag values. I had the system running on my desk for approximately a month with no problems.

This morning the panel failed. Hopefully the problem can be identified in the RMA process.

I have an installation where during testing, a QTERM-A7 panel was working fine -- CPU at a few percent.

Now after a month of operation, the response to touches is slow ~15-20 seconds, and the canned diagnostic screen reports the CPU at 100%.

Is there anyway to troubleshoot the problem?

There's an option to turn off the backlight after a fixed amount of time but is this required? Can you get burn-in on an LCD?
