    beenwriting, Samsung KNOWS they have a problem! If your unit is less than 36 months old you still might be able to get a replacement FOC. try calling Samsung at 1 800 samsung. If possible find purchase recipt. If you can't get any help at samsung then get back to me at fixya and we will try to help you out. Your described symptom sounds like the 931B might have a power supply failure. louie12fix or lmistyrel @aol.com Even if Samsung replaces your monitor, please get back to us and tell us about how well they did about replacing it!!!! We want to know!!

SOURCE: blinking blue light

You have to check if you can see the image on the screen or not after it went blank (Power on both CPU and monitor) 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. Like mine, I can see window image using flashlight and check lamps inside. 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.
Thank you

SOURCE: my samsung syncmaster 2232bw wont turn on at all,

Solution for Samsung SyncMaster 2232BWplus:

The problem is bad capacitors: 5 pcs. 820microFarad – 25v and 1 pc. 330microFarad -25v. Replace these capacitors. Then re-solder the two transformers of inverter side. Also re-solder the power transformer and the inductor coil.
To open the casing:
At the bottom of the stand just twist the knob to unlock. Then, use a small flat screw driver beginning from the bottom (left or right) then using a hard credit card (or alike) then slide/glide it in between the cover plastics.

Samsung syncmaster 2220 blinking blue light and no image display


Here's some tricks I would try...
1. Verify the monitor's power cord is plugged firmly into the wall outlet and the back of the monitor.
2. Verify the monitor cable is firmly connected to the computer and the monitor.
3. Verify that you have turned the monitor power switch on.
4. If the power light on the monitor is not on, test the wall outlet (plug in a light or something you know works).
5. If the power light on the monitor is not on, try a different power cord.
6. If the power light is on and yellow or orange or flashing, but nothing displays, or the display is incorrect, borrow a monitor from a friend. If that works, your monitor probably needs replaced.
7. Also, you could try your display on a friend's computer. If it doesn't work, your monitor probably needs replaced. If it works properly on your friends computer, the problem may be with your computers video output port, motherboard video chip (or video card, if you have one), or drivers.

Good luck.

Black screen with power switch flashing blue.


I have been same problem but in other type syncMaster, the solution is open your LCD monitor look for power supply module (PCB which have connector to AC power), on that PCB look for capacitor , for normal condition its look like small tube. now look for broken one which upper part is bloated.
