Hi this is the way how to examine what's wrong with your LCD monitors. After you turned it on and the screen blacked out or stopped working, you have to check that if you can see the image on the screen or not by shining a flashlight into the screen, not directly but find the best angle to the screen and take a look very closely. If you can see the icons or any image, there will be a minor problem. This is because of the lamps inside screen. Some of them were broken and it is very easy to replace. If you cannot see anything on the screen, there'll be some problems with inverter board. If you have soldering tool and want to fix it by yourself, check the caps first. It may cause this problem. Some caps might show leaking or burn spot on the board because of too high temp. If you don't have soldering tool, you better go get a technician to do so. Hope this help!! If anything I can help you with, feel free to let me know.
Thank you,

You should have received two cables with the monitor. One is for VGA and plugs into you video card or computer board . The second one is for DVI digidal video and if you have that cable it plugs into the square connector. Then if you look into your monitor manual or quick setup sheet it will tell you how to connect and set the monitor to either VGA or Digital. I'm sure that is what has to be set. Don't hook up both cables to the monitor and computer. Only use the one. Digital gives you a better picture if your computer has that function. Hope this is helpful. Bud

Hello cstafford35,

Your monitor has a very common problem. The internal power supply has blown a part called a capacitor. If you are comfortable working with electronics and with soldering I can talk you thru the diag/repair. If you are not ready to tackle that we also offer a repair service, about $30 plus shipping for your model. Let me know if you want to try fixing it yourself and we can go from there. The repair will require opening the monitor case and replacing from 2 - 5 parts. You can call me at 318-447-9040 if you have questions.

This problem may be caused by defective capacitors on the power board. This fix requires techical skills and should not be attempted by anyone not familiar with such work. If you still want to attempt it, here are some instructions. You will need soldering skills and equipment. 1. Remove the back half of the case. It does not connect to anything inside the monitor, so it can be removed completely. Remove the pedestal by unscrewing the wing-screw on the bottom, This allows good access to the slots on the bottom of the case between the two halves. Use a screwdriver about the same size as the 2 slost, insert and twist at each. You may want to wrap some tape around the blade to protect the plastic. Work your way around the case using a second screwdriver to keep separation. Use the corners especially because the plastic is stronger there. Remove the back. 2. Unplug all cables for the metal pcb chassis. The 4 small ones have 2 plastic covers that unsnap. 3. Lift the metal chassis and flip it over. 4. Remove the 4 screws holding the main pcb and lift the board and flip it over on top of the smaller board so you can see the capacitors. 5. Examine the caps for bulges, replace any that do not look flat on the top. Try Radio Shack for replacements. 6. Reassemble by following these steps in reverse. Note: the metal chassis is resting on but not fastened to the panel, and is restrained by tabs in the back cover, so keep that in mind while snapping the cover back on.

Screen wont show cameras or record


Are you pressing menu button on the monitor or the DVR?
Your problem may not be the cameras, but between the DVR and the monitor. Found this on page Eng-19 of the user manual which I found on Samsung.com
This monitor was set to password lock when you purchase a new set. Therefore, you must first enter a 4 digit password to activate the On Screen Display... the default password is 4321. Not sure if that helps.

sales660, Monitor should not be doing that!!! Use Samsung warranty if available. Complain about "premature failure". Examine black screen for very faint displayed image with aid of bright flashlight(test all owners of CCFL back-lit lcd displays should know) to determine full or partial SMPS shutdown mode. Read more in my fixya profile for more that you can do. It could be bad capacitors or a thermally intermittant solder connection that you or qualified electronics tech will need to fix if warranty not option. After reading and surfing net you will understand your CCFL back-lit lcd display and how it works. Your monitor no different than ANY other brand of CCFL back-lit lcd monitor in it's basic design and operation!!! 12fixlouie

Screen goes black but power light stays on


Hello. I had the same problem with my X2gen 19" (model MW19R)monitor. In my case, the monitor would turn off after 20 seconds or so but the blue power light would stay on as well. I had to replace a high voltage capacitor located in the backlight power supply board. There are 4 blue capacitors on the board which are identical and they are marked as 27J 3KV. Fortunately, I only had to replace one of these capacitors ( it was turning a yellowish brownish color ). Hope this helps.

Samsung SyncMaster 215tw screen goes black after about 1 sec.


I have the same problem its defenitly a problem with the lcd monitor not with the graphics card nor the pc. I hooked up the digital and afterwards the vga connection both had the same result. 1 s perfect screen all visible but than black. pushing the on/off or standby button again shortly 1s the display works than it blanks. Did the same test while connected to a dvd player via the composite video... same problem . Since the previous posts are that old and without a solution I guess there is no hope in getting it fixed.

Monitor black screen


Your first step in troubleshooting this problem is to plug in another monitor to your computer. If you are having the same problem it is related to your computer. If the second monitor works fine then your original monitor is shot.
