Star Controller LCD Screen troubleshooting steps
Posted: Fri Apr 17, 2026 7:51 am
My LCD Screen started to act strange, occasionally non-responsive. Now this nuisance has degraded into flickering and an unworkable controller that appears to reboot itself, flicker between a red and green LED and otherwise not be helpful. Then these symptoms change again if I remove all wires and USB accessories. Replacing the controller logic board just gives a green light but not even a flicker from the LCD. I have searched the forum and I don't think posts from 2013 apply to a star controller. I'd like to start from the beginning.
What is the recommended order in which to diagnose and fix what started out as a nuisance intermittant touchscreen response issue that has developed into a looping star controller.
