Its the capacitors on the backlight power supply. Samsung installed crappy ones and they blow up after a year or two. Change out the caps and you're good to go

SOURCE: Samsung monitor picture clicks off after 2-5 seconds...

Yes, It sounds like the backlight inverter circuit is shutting down. No inverter power, no backlight. On some monitors the inverter circuit will shot circuit the power power supply which makes the power light flash on some it just kills the backlight. You can usually check with a flashlight. Hold the flashlight pointed at the screen and see if you can see any of the icons or background picture. If you can then it is the backlight circuit or backlight tubes, usually the circuit.

SOURCE: blacks out after two seconds of display,

I had the same problem with my vx2235wm. the symptoms were it would power on with no signal and the blus light would glow. when the PC was turned on it would kick back to the "power-save" state and the desktop would disappear.

To fix this you need to take the case apart (3 screws, one is behind the stand, then gently pry it apart starting at the bottom with a flatscrew driver and pop each tab carefully every couple inches, along both sides and a final wiggle to free the top edge.)
Inside you will find a metal cover, to remove this undo the screws holding the power supply and display ports then unscrew the screws holding it on.
Take notes of where the wires going in are oriented and then you should be able to see two boards.
In this case the suspect part is the DAC which the power supply goes into. On the DAC there will be a part number. In my vx2235wm it was DAC-19M009. Buy the whole board online. Mine shipped for around $40 total. Wait 2 days for it to arrive and installation is pretty much reverse of removal.
My dead display is back in comission, hope this helps with yours.

SOURCE: dell E228WFP monitor cutting off, goes black

sysjrm, You need to visit YOUTUBE for video clips of "lcd monitor repair" to see if DIY project is what you can handle!!! After you "learn by seeing" some printed circuit "switch-mode-power-supply/inverter boards" having their "aluminum-can" electrolytic filter capacitors replaced and/or "thermally-intermittant" fractured solder-joints "resoldered" then you will be able to make decision on what to do about attempting a repair to your E228WFP! Note!!!! Make certain that your pc is not the cause of your BLACK SCREEN or BLACKnBLANK SCREEN problem/symptom by connecting a "known-good" monitor to your pc first!!! Please read the higher numbered(32 and up) pages in my fixya profile for more information on how to do the simple "flashlight test" for evaluating the state of shutdown that the switch-mode-supply may be in. Also read and follow the links you find in the profiles of "budmrtn" and "buddymc" that are very good ccfl back-lit lcd monitor technicians here on fixya. After you do your web research, remember to come back to this posting and do a comment and rating of this response if you feel that it has steered you in the right direction. Good luck with the repair. 12fixlouie

Samsung 244T 24" LCD Monitor suddenly lost


Hello,

The problem you are having is a common symptom of a failure in the power supply. Parts called capacitors start failing. When they fail they stop filtering the voltages correctly and the power supply shuts down to prevent additional damage. If you would like more information on capacitor failure please check out this page on our web site explaining what they are and what they do: http://www.ccl-la.com/blog/index.php/capacitors/ If you can solder then you can do the repair yourself. We have a kit available with all the capacitors that you need to replace. The kit details can be found at: http://www.ccl-la.com/catalog/product_info.php?products_id=124 The kit contains all of the capacitors that need to be changed on the board to return it to full operation again. If you don't want to do the repair yourself we do offer a repair service for this unit. You can get details on our repair service at: http://www.ccl-la.com/blog/index.php/service-request-form/

I hope this helps, if so please rate our solution.

Syncmaster 226CW showing picture only for a second + flickering


Hello,

Call and get the RMA for your monitor, the problem is in the power supply and it will only get worse. This is a common problem with LCD monitors after 2-3 years of use.

Samsung 226bw visible flickers just after it is turned on


You may have a faulty inverter or loose power inverter connection. OR
You may have a defective CCFL backlight, it may have the following symptom: Screen flashs on red/pink and off. Picture stays on in red and slowly be come normal. Picture flickering with dim display or appear black. Picture flickering on and off. All these symptoms indicate that the LCD backlight lamp (CCFL Lamp) has reached the end of the life and all you need to do is replacing the CCFL lamp.
Connect an external monitor to your laptop and power the monitor up first then the laptop, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight. Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight and it could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out or burnt out, most likely this is the case.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.

Computer monitor flickers


Sounds like the lcd ribbon might have come loose. Or the lcd screen itself needs to be replaced. I have included a link here. The website shows detailed pictures about how to access the parts needed to fix this problem.

The ribbon i'm speaking of is just like the vga cable you use on a normal monitor. Since there is a limited amount of space in notebooks they turned this thick cable into a small flat ribbon.

Try to look and make sure all the connections are tight and as they should be. If nothing changes you will have to change the LCD display.

Flickering picture


chech out some other devices near by to the monitor, they might cause interfearence and in a result your monitor flickers.

1. If there is nay CVT/UPS near your monitor put it away.
2. If you have any speaker without magenetic sealed it will cause flickering, keep it away from monitor.

Otherwise your monitor need to be get service. So please contact your manufacturer service centre.

Thanks

Monitor only stays on for 3 seconds


There is probably a bad capacitor within the monitor that will not allow the picture to "hold" in the on configuration. This will need to be replaced. You can send it back to Phillips, or 17" monitors are pretty cheap these days. I would suggest a Samsung or BenQ. They both carry 3yr warranties.
