Question about Samsung Computer Monitors
Menu for syncmaster 940s is a disaster. I have put up with it for years but now it has totally defeated me. How do I turn off magic color demo?
PS I have worked in broadcasting technical and have no problem lining up three tube color cameras. But the the program for this monitor has brought me to tears. Something like your web site
Does the monitor remain on does it switch off?
Problem seems to be hardware related ie monitor itself is defective.Try connecting to another known working system.If monitor is defective it could be a power/inverter related issue or panel could be defective.
Please provide feedback and rate the solution.

Have you unplugged the power cord to the LCD? Let it sit for a minute, then try it. ALWAYS buy a UPS and plug any computer devices into it. Doesn't have to be big, a $50 unit will protect it from dangerous voltage surges.

rcpips, You may need to replace one or possibly 5 -8 aluminum can "electrolytic filter capacitors" on the "switch-mode-power-supply/CCFL inverter board. If, as you say "works for 5 or 6 seconds" then that means that fuse is good. Another thing you will need to inspect SMPS board for is "cold" "frosty looking" solder joints where the components (surface mount or through hole) are soldered to the copper circuit traces. May need large magnifying glass or low power inspection microscope to locate them. Resolder any that look bad or loose. Some solder joints have thinner than "hair" thermal fractures that can also cause YOUR TYPE OF SYMPTOM!! PARTS: digikey. mouser. newark. and possibly Radio Shack. If buying filter capacitors, make sure they are rated 105 deg C only!! NOT 85 deg C!!! If caps need to be replaced (swollen, leaky) be sure to tell us the brand name you find installed on your unit! CAPXON, ELITE, JUN-FU are just 3 that you don"t want to find in your unit. BAD news if you do!! If DIY suits you, remember to document with "close-up" digital stills your unit tear-down, so you can reassemble unit without any "extra" parts laying on kitchen table!! Filter capacitors are polarized. You put them in + to +, - to -!!! if you put them in backwards they go BOOOOMMM!!! Hope this helps a little. lmistyrel on aim or 12fixlouie at fixya.

They are referring to the video card in your COMPUTER, not the monitor. There is a supported list of cards at http://www.samsung.com/Products/Monitors/magictune/magicrotation_06s.htm

Sounds like the backlight has failed. The backlight illuminates the liquid crystal display. Without it, everything's black. Though, as you observed, if you get really close you can still see something of the image.
