Question about Samsung SyncMaster 910MP 19" LCD Monitor

1 Answer

Samsung GH19LS LCD Monitor wont display computer signals

The monitor turns on, displays the message "Analog" then "Digital" about 6 times and then the monitor turns itself off. A pressing the menu button on powerup shows the message "TEST OK", but the issue is that when the monitor is plugged into a PC, 2 pcs and 2 laptops have been tried, the monitor does not display any computer generated image.
Since the backlight powers up, and the monitor displays the messages on the screen, I also tried a couple different cables between it and the computers, but nothing different. Can anyone provide some idea as to what this problem may be?

    Thanks for your comment. I have since contacted Samsung, and discovered another person with this same problem. It turns out that this is a common problem with this model, and stems from the video driver board going faulty. The monitor is 6 months out of warrenty and it will cost $55 for them to look at, and possibly $140 more to replace the video board. I am dissapointed, since this monitor seems to actually work, but wont display the picture of the incoming computer screen. Both the DVI and VGA connectors are effected by this problem.
    I think that I am now asking for assistance, with the expectation that a hardware solution is required. :( But I am not adverse to this possibility, if someone has guidance.

    I have exactly the same problem with the same LCD. As for a different input cable, No such luck here, Looks like I got the cheaper model with only vga input!

    I'm looking into the controller board problem and will post as much advice as I can if I can solve this problem.

    I have this LCD open on my desk, It is the controller board. I'm googling for spares using the part numbers and nothing! ... Not a sausage! Whereas my Xerox xm7 19w I can find spare parts no problem!

    Any ideas where I could find spares?

You should have received two cables with the monitor. One is for VGA and plugs into you video card or computer board . The second one is for DVI digidal video and if you have that cable it plugs into the square connector. Then if you look into your monitor manual or quick setup sheet it will tell you how to connect and set the monitor to either VGA or Digital. I'm sure that is what has to be set. Don't hook up both cables to the monitor and computer. Only use the one. Digital gives you a better picture if your computer has that function. Hope this is helpful. Bud

After starting the computer the screen is black and only displays digital analog on screen and the blue light is flashing. It then displays a box say "check signal digital analog." please help me. Thanx.


This blue light flashing means there is power to monitor bu NO video signal. No Analog or digital Video . analog is the regular plug for PC to Monitor, the other is HDMI digital or other digital. Check signal digital/analog means again: No video signal from PC detected.

You may be blaming the wrong device. I suggest you try the monitor with another system, the problem you describe could be located in the video output of your system instead of a monitor fault.

No digital signal but analog works fine


Seems like this was already answered? But once you've checked against the owner's manual and ruled out the PC, I would suspect the signal / video board inside the monitor. May have gotten a surge or static, etc.
