SOURCE: Samsung syncmaster 245bw is black

You need to check and see if you are getting the 24vdc feeding the backlights inverter board, also check the fuse on the inverter. Does the backlights flash on for a second at all?

No screen power up


There are one or two open capacitors in the power supply, they often have a bulge at top due to leakage.

Samsung SyncMaster 245BW - no image - screen flickered once or twice and then went dark. Reconnected cables, tried different cables - all with same result - no picture. Any usggestions?


It may ahave 24vdc power supply problem due to bad caps, ect, or bad backlights inverter board, worst case will be the lamp assemblies. It will require in-depth troubleshooting.

Samsung Syncmaster 245BW displays no image. Unit receives power and the blue LED on the power button is lit but the screen is not illuminated. I can't tell if the pixels are changing at all, but there...


laqbot7000, If you have opened unit, what is the brand name of capacitors (electrolytic's) printed on them. CapXon, Elite, Jun-Fu, are some you don't want to find on the smps board. Are any of the rubber seals pushed out of the bottoms of any capacitors? Is fuse still ok? Did you use a magnifying glass or low power "inspection" microscope(5x - 20x) to possibly find any "thinner than hair" fractured solder connections to component leads soldered to the copper foil circuit traces?? Also "visual" the black bodies of all solid state (transistors, bipolar, mosfet) devices for "burns" and "distortion" from overheating. 12fixlouie

My Samsung Syncmaster 245bw LCD displays a blank screen.


wardysbiz, I should think SAMSUNG would ship you a replacement unit. It might be what is called a REFURBISHED unit of same model.
In future try not to use the word BROKEN. I thought an elephant stepped on it, or it fell from a great height. Try "nonfunctional" or "inoperative", "has failed" , "never worked" "out of box failure" "Dead on arrival unit" Also contact NEWEGG and ask lots of questions about quality and reliabilty of lcd monitors. Find Your sales receipt or card statement to prove pop. Don't let them off the hook!! I would think turn-around process to be about 14-20 days. 12fixlouie

My syncmaster 245 bw will only display a blank screen through the dvi port. Another crt monitor works fine through the vga port . I'm running a nVidia 7800 GS video card.


You need to adjust the monitor refresh rate to 60 Hertz or 70 Hertz.
Use the CRT first to adjust it, then after adjust,plug in your Sync Master to see is it perfect or not,find the best frequency that work best.

To adjust it,right click on the screen,enter properties, then click setting tab.
Then in advanced tab, click it then you see the monitor tab, find the perfect screen refresh rate.

Blank (dark) notebook screen after hooking up digital ext monitor


I notice a difference in the setup of the two monitors, have you installed the correct driver for the new screen?

Try F8 on startup to get into safe mode, this should allow you to use the default VGA screen, and to reset the correct monitor drivers.

245BW monitor not working (stranges colors ad aeternam...)


I had the same problems as almost all of these people and the answer seems to be that I uninstall the current Nvidia Drivers and use a previous set. The 169.28 were a real problem for me. Just when I thought it was working I would get the strange wash out and I could not turn it off except with the back power switch, aslo using the DVI turns off all the on screen controls.

Good Luck
