Hello, we installed a Grafik eye system (QSGRJ-16E) in my office over 3 years ago and now have run into a problem. We had a power outage last Friday and once the power came back online, the lights began strobing. I reviewed the controller and everything seemed to have saved as far as programming goes, but they don't stop strobing until I turn them off. Thoughts on what can be causing this issue and how I might resolve the problem?
