Question about Samsung SyncMaster 940MW 19" LCD Monitor
Have recently purchased and have only used as tv. Sometimes even though plugged into an active outlet, can not get any green power light at the screen. A day or two later it will work ok. Sometimes after minimal use it will shut down or it will go to a mode where none of the remote will work. Unit worked good for the first couple of weeks without any of these problems. Have not used it with a pc yet and have not configured it with any supplied software as yet.
As with most Korean & Chinese manufactured products, the quality of construction in the factory can be less than desirable. We often find problems of this nature to be due to poor connections:sometimes it's as simple as the various cabling & harnesses between individual circuit boards & modules (those going to the light engine in Samsung DLP & LCD sets are notorious), but more commonly it's about the lead-free solder that the E.P.A. has mandated must be used in new electronics products for the U.S. market---lead-free solder requires higher temperatures to flow than older lead-based alloys, while the wave-soldering robotics used by these manufacturers is apparently still capable only of what they were designed to do, i.e., working with lead-based solder. Perhaps 25-30% of the problems we repair are of this nature...

I have same problem too. My monitor shut itself every 20 to 30 minutes.Only way i bring'em back on is unplug the monitor.But this is not the solution.

There is a high resistance short between the pins on the board for the channel/volume/power etc. buttons. This can be verified by ohming between the pins on the board. Clean around the pins to remove the short.
