I have two XU 300 projectors and they both are basically doing the same thing. They are hooked to Extron MLC boxes and you can go check them out press the ON button on the Extron and everything comes on OK, you can control all functions from the Extron OK. Leave, and then a couple days later somebody will call and say they are having problems. You ultimately have to unplug the projector and plug it back in to get anything to work. After you do this the projector will work fine again for a few days and then do the same thing. Anybody had any issues like this? I thought it was the Extron Serial Driver but I spoke somebody else at the college that was having the same issue and they did not have an Extron Controller. Thank you
