Hello,

Your internal power supply is failing. There are parts called capacitors that are not functioning correctly and this causes the power supply to not be able too stabilize the voltages that run the monitor. After repeated power cycles the capacitors will hold enough charge to function until you urn the unit off and then they discharge so you have to start all over again. We have a step by step repair guide article posted at: http://www.ccl-la.com/blog/index.php/samsung-204b-lcd-monitor-repair/ This should get you back going again. If you don't want to do the repair yourself we do offer a repair service, you can get that information here: http://www.ccl-la.com/blog/index.php/service-request-form/

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

I have a Samsung Sync Master 731BF and when I switch it on, the power light stays on but the image is black and wont show any picture whatsoever.


Hook a spare monitor to the computer to rule out the Video Graphics Card in the computer, if okay! It is the Samsung, "power supply issues" bad capacitors, sometimes show a bulge at top. But to be on the safe side replace the video cord from the computer to the monitor if possible.

The screen is all yellow. i am using samsung sync master 713N. it was working fine but now suddenly all white has turned light-yellow.


It does sound like a bad monitor, but first! hook a spare monitor to the computer, if okay The Samsung SyncMaster is the problem, caused by the master board which is attached behind the LCD display, the video signals are feed to the main board where the colors are balanced. To repair this would not be cost effective "cheaper to buy new" Now! if the video cable from the computer to the monitor can be detached, sub another cable just to be sure. Finally if both monitors show the same issue, the problem is in the video graphics card of the computer.

Hello,

The slow startup is an indication that your power supply board i failing. The board tries to power up but the voltages are not stable so it shuts down and retries over and over until they do level out and you get a picture. This will get worse until it dies all the way and you get no power at all. The repair involves replaceing a few parts on the board. If you can solder then you should be able to do the repair yourself. We have an article posted here that shows what needs to be done: http://www.ccl-la.com/blog/index.php/service-request-form/ The 731 uses the same power supply board as the 720. If you don't want to do the repair yourself we do offer a repair service, here is more information on that: http://www.ccl-la.com/blog/index.php/service-request-form/

Mine shut down during my normal working day. Same thing, turn it off and on again - screen flashes up briefly then flicks off again.
Called Samsung and they are replacing it with a refurbished screen under warranty.
