A: This is a fairly common problem at Sheridan. Infact, you have probably seen your teacher call ITSC on a regular basis, they come down and do nothing but turn it on and it works fine. Here is why. The NEC projectors have a fairly long warm up time, when turning the projectors on with the remote, you want to HOLD DOWN THE ON BUTTON FOR ATLEAST 10 SECONDS. The 10 seconds is non-negotiable, if you do not hold it for atleast that period of time, you will get no love from the project. Count missassipis, I'm serious.
