content: I've had my 940MW for over a year. When 1st received, after turning on, it would work for 5 to 10 minutes and then cut off. I tried removing and re-pluging in the power cord and it would work for a few minutes and then the monitor would again cut off. Then I tried a different approach. I removed the power cord and squeezed the end that goes to the monitor with regular pliars. SINCE THEN, THE MONITOR HAS NOT 'TURNED ITSELF OFF' ONCE!I believe that what was happening, in my case anyway, was the power cord connection at the monitor would heat up and expand and break the flow of AC. Squeezing the power cord with the pliars 'tightened up' the connection allowing the cord to maintain contact. I looked at the monitors plug hole after removing the power cord, and the connection lugs were inset into the monitor farther that I think they should be. I think that that caused the problem.Don't know if this helps anyone else.That is the only reason I don't give this monitor a 5 rating.
