Hi Detrix, Check with if you want a repair. Something is wrong with your LCD controller and or GUI interface circuit or the circuit supplying power to it. If your technically endowed, you may want to open the monitor case and clean the dust and lint from around the circuits using a Small paint brush to sweep away any built up dust. These circuits take the Signal from the computer and controls the 2.5 million pixels on the LCD screen. Dsut can cause major problems with handling all that data. Give it a shot, what do you have to loose, its not dangerous if the monitor is unplugged.

SOURCE: monitor screen looks dark but if you look close you can see image

husslin, Yes, you too can join the crowd of people whoose LCD/FPD power supply and or Cold-Cathode-Fluorescent-Tube power supply(called an INVERTER circuit) which supplys hi voltage to light up the backlight tubes so you can see all the pretty colors on the front of your screen has failed.
If Samsung won't do a swapout, you send them your's plus some cash and they send you a same model refurbished unit in exchange, then most likely you will need to effect a repair on your own. The fact that you are able to see the image ( Windows Desktop or IE) is a good sign. It means that the MAIN POWER SUPPLY board is at least supplying voltage to the logic/video processor board inside the monitor. LCD/FPD displays have 2 or 3 printed circuit boards, not counting the tiny board that has the on/off and adjustment switches on it. The large board that is connected to the AC line will be the Switch-Mode-Power-Supply which may or may not include an on-board Inverter circuit. These SMPS/INVERTERs have 2 causes for failing. Either one or a combination of the two. Failed ELECTROLYTIC FILTER CAPACITORS from thermal stress, and or other heavy components whoose leads are soldered on the bottom of the board have developed circular stress cracks in their solder joints. Well, I've probably told you enough to get both of us in trouble, but if you surf over to youtube, do search for vids on lcd monitor repair and or bad capacitors or swollen caps in lcd monitors. Got to run now, but you can get back to me at louie12fix on fixya or lmistyrel@
PS look for vids on lcd dissaembly or such. I have seen some about 10min long.

SOURCE: My flat screen Samsung monitor flickers on and off

or it could be the cable? if you have a different vga cable you can try that, if that's not the problem then it sounds like your lcd is possibly dying. you should also look at the pins on the vga connections and make sure none of them are bent

SOURCE: I have a Samsung SyncMaster 931c monitor (2.5 yrs

jcacolice, Most likely your 931c will need work done on it. When strange things start to occur with any LCD CCFL backlit display I would suspect the "switch-mode-power-supply" first thing!!! If unit is out of warranty you or someone will need to inspect and troubleshoot it. A good place to start will be to see some DIY videos on YOUTUBE. Try search of "lcd monitor disassembly" and "lcd monitor repair" and learn all you can about the TOP CAUSES of monitor failure. Then visit (FYI) and for more info. Explore ALL your options before you do anything. Then get back to us here at fixya if you still need some asssistance. Read some of my other responses in my fixya profile and other those of other tech's on fixya.
Hope to see you back on fixya with a plan of action!! 12fixlouie

SOURCE: Problem with Samsung 17" Syncmaster 793 MG monitor

As you said the monitor is OK. the RAM in your system is not working so you are not able to see anything when you turn on the monitor. Replace or reconnect the RAM and check it once again.

My monitor shows image immediately when switched on but just as soon the image appears the screen of the monitor goes dark after that need to off/on the power switch three to four times before the image...

Please restart your computer and tap the F8 key as soon as you see something on the screen. You should get the advanced boot menu. Select Safe Mode from the list.

Let me know if you were able to boot to safe mode.

White line appears in the middle of the screen

please describe the issue better cause it doesn't make sense..are you saying that your screen background is black no matter of the picture you choose??or that the image of the monitor is just showing a black screen??in the case I sescribed ..if the operation system seams to work but you can not insert any pictures anymore on wallpaper and it is black ..and a genuine advantage program is inserted a banner in the tray system ..(right ) ..this is a case that yous windows is not genuine and the warrning was placed after you check it on a installation get rid of it ...just make a search in the start for a file named..WgaLogon.dll ..and after you lcate it ...rename in by changing a letter in th emiddle (ex: WgaLogTon)..and restart the computer ..after this the functions will be right back ..insert another walpaper and go on ..
If you are talking about the image being just a white line in the middle and the rest is black like it is shut down..than the issue is caused by a condenser burned on the image should have it checked and changed..

Screen jumps back to prior screen

If you mean to say that the computer-generated displayed image on your screen changes, it's a function of the computer, not the monitor. If you mean to say that some monitor-generated displayed image is appearing (such as a setup/configuration menu or a splash screen), please tell us more so we can diagnose further.

Acer X193W Monitor / screen image

Check your video card drivers are installed correctly.
If unsure, the reinstall them again, it won't hurt the system and there are probably new drivers out for it anyway.

Screen image display distortion

What you are reporting is a problem in the pincushion circuit in the horizontal section of your CRT monitor. Usually this is from an electrolytic capacitor that is no longer willing to play nice with all the other components.
It is repairable, but get an estimate first. If the repair bill appears to be around $100, you would be better off to put a few more dollars with that and buy an LCD TFT monitor.
If you are quoted $25 or $30, it is probably worth having repaired. Just keep in mind that these older CRT monitors have age on their components, and once repaired, it will still be an old monitor.
Only you can decide which choice is right for you. At least now you have a few facts to help make the decision.
I hope this helps.
