Question about Samsung SyncMaster 940MW 19" LCD Monitor

3 Answers

Intermittent Power Supply

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...

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.

No use troubleshooting it any further. You know the AC outlet works, OK, right!
Sounds like a warranty claim to me.
Power supply in these units are all switch mode these days. Basicly a digital controlled (switch on/off at very high speed with feedback) power supply. So, even if you can find the internal fuse there is not much you can do except replace a module. Sorry

Won't turn on


This is a clear failure of the power supply or the control panel due to the power outage and so will require that the power to the unit internally is checked. Sometimes this can be due to a fuse blown out or a control panel failure within the unit due to the intermittent fluctuation.

I have an old Panasonic TV that has recently started shutting itself on/off. What could be the problem? Advice?


Make sure the TV is not plugged directly into the wall outlet use a surge suppressor or protector to avoid AC spikes which can kill the TV's power supply board. If the TV has multiple media inputs this could put strain on the power board and cause thermal conditions to rise which will trigger detection circuits and shut the TV down temporarily. If nothing else it seems as though the power board needs servicing but it could also be a main board intermittent fault also. But try the above first see if that helps any...

My laptops screen does not come on even though the unit powers up,i have tried another screen,and tried using external monitor,neither worked,the lights by power button also don;t light.


Did you check the power supply? They go bad and if you get no power, nothing else will work. You can check the power supply by plugging the unit into an outlet and then using a volt-ohm meter measuring the voltage at the cylinder which normally plugs into the computer. If there is no voltage (DC) present, then the supply is bad. You can get a replacement online or at the place you purchased the unit.

My computer won't turn on! It seems like no power is getting to it, even though it is plugged in and SHOULD be working fine. Please help!


check if your power used to connect form your CPU to the outlet is not defective...use a multitester to test the said cable,,or simply use another power cord and conenct it from your cpu to the outlet...if still the same you have to purchase a new power supply since there is no power and your curretn power supply is already defective.

The TV will not power on with remote or manual button


Have you had any major power outages in the days leading up to this issue? It could be a power source, cable or outlet. Try different outlets if you can and see the tv responds.

Best of luck,

Make sure the power supply cable is tightly plug-in, the one in the back of the TV. This fixed my problem.
