Hello,

The usual cause of this type issue is the power supply not the backlight bulbs. The power supply will start failing because of parts called capacitors that overheat and bulge so they can't hold the charge like they should. We have an article posted on our web site that explains better what they are and how to tell when they go bad. It can be found here: http://www.ccl-la.com/blog/index.php/capacitors/ If you can solder then you should be able to do the repair yourself. The 731s use the same power supply as the 720 series and we have a repair guide for this series. It can be found here: http://www.ccl-la.com/blog/index.php/samsung-930-and-720-series-repair/ If you don't want to do the repair yourself we do offer a repair service, you can request service here: http://www.ccl-la.com/blog/index.php/service-request-form/

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

Might be from overheating, monitors do overheat sometimes. I had the same issue happening to one of my old monitors and it wasn't fixable unfortunately. I had to replace it and get a new one.

Samsung 920nm sync master Black screen


Samsung sync master monitors were well known for bad capacitors, if you have a esr capacitor meter you can check in circuit, if not look for dome shape at the top of the capacitor, a dead give away it is open, also check for poor solder connections in the power supply inverter board area.

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.

Samsung syncmaster 731bf screen stays white!


It sounds like the T-CON board (part of the LCD panel) is not getting the +5vdc from the logic bd. Check the ribbon cable between the panel and the logic bd. first, then check to see if it has blown fuse on the T-CON bd.

Start up problem with Samsung Sync Master 731BF 17" monitor


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/

The screen flick when connected to Samsing Sync


Hello there!

Screen flickering can be caused by instability of cable you are using, or it can be also caused by difference between power input, so check your power plug ,where your monitor and pc are plugged, make sure they are ok for your region, and check those cabels. Also check settings on monitor for what input you are using DVI or VGA or both at the same time.

A 20" monitor gets a black screen when turned on


sounds like you might have a back lighting issue? take a flash light and shine it on the monitor when it is black and look to see if the image is there but not lit up, if this is the case then you might need to change the light balist in the monitor of even the back lights themselfs..
if the picture is fuzzy for a long period of time then you have a controler card issue there is a controler card in the monitor that changes the image coming in from HDMI, VGA, DVI into the binary that the vertical and horizontal drivers use to show you the image onthe screen... hope this info helps. good luck

Dell 2005FPW Monitor Flicker problem


The flickering is most likely the florescent backlight having a hard time starting, Just like in a light fixture, as it gets old, it takes longer to warm up to get full functionality.
If under warranty, contact Dell for a replacement, if not, then when it becomes untenable, replace the monitor. Prices are dropping drastically, an new 20 or 22 In can be bought for about $150 or less

Flashing on and off


I would suggest trying another monitor to rule out your PC or monitor card. I would also check the video settings on the PC. Then assuming your cable/connector and video card are okay, it sounds like a lamp or lamp driver (a.k.a. ballast or inverter) issue. In other words, an internal issue that probably needs component-level troubleshooting.
