Question about Samsung SyncMaster 710N 17 in. Flat Panel LCD Monitor

2 Answers

No video picture

I have a Samsung 710N LCD and I cannot get a picture on it, comes up with a box saying that it wants to run in optimal resolution of 1280 x 1024 but when you change the computer to that resolution then it still does not display a picture from the computer, has anyone experienced this fault with this monitor and can you help or suggest a fix or what the problem could be?
Thanks and best regards!

    The monitor goes off after working for some time. Then even if we reboot it wont work for some time. After some time it works as normal.

    My SAMSUNG 715v 17" LCD Monitor will only display 1280 x 1024 VIDEO RESOLUTION RECOMMENDED. even if i tried using another monitor just to adjust the desired resolution, after installing the SAMSUNG 715v, still it won't work. Before this problem goes on steady like this, it has been occurring intermittent in such a manner that it will display normally a couple of minutes then suddenly it will BLANK out and display the 1280 X 1024 VIDEO RESOLUTION..... msg. Now it totally won't display normally - just the Video Resolution msg. Is their any solution to this problem?

    I have a Syncmaster 710N which also constantly displays the "non optimum mode 1280 x 1024" msg. I have tried to connect the monitor to a system that had this display setting determined - no go. I then hooked up another system with a separate graphics card (the previous one had onboard graphics) with the same result. I have also referred to the troubleshooting guide in the manual -again a no go. Yet the LCD shows the pre-test screen OK but then returns to the infamous "non- optimum...." msg. I read somewhere that if the LCD displays this message continuously then a PCB will need to be replaced in the monitor. I was looking for some kind of reset button somewhere and have almost reached the point of throwing the "piece of ****" in the bin only to keep reminding myself that there must be a quick fix for this. I did have a glimmer of hope when I unplugged and replugged the monitor in and the display momentarily came up only to revert to black in a few seconds. Any suggestions would be most welcome.

    Everything is OK until the PC enters the screen saving mode.
    When the PC comes out of the screen saving mode the 710N displays a message about not getting the optimal resolution, though the video is the same 1280x1024/60Hz as before. After that, when re-booting the PC the monitor displays the BIOS screen and the first XP boot screen OK.
    Then it goes blank and displays the same message about not getting the optimal resolution, MENU key not working.
    Powering it OFF and ON shortly does not help.
    It behaves OK again only if left unpowered for more than 10 minutes.

    my 710n does not come on after restart. it shows a dialog box about resolution/frequency. it works if i leave it for a while (power switched off). i believe this to be a known issue and samsung will replace if under warranty.

I just did the 50ohm resistor deal on a 710N I found next to a dumpster. I actually put 47ohm radio shack resistor between J5 and J6 on the NT68F63LG chip. Worked like a charm! Thanks!!

It wants you to set the PC video card video output to its native resolution (1280*1024 60hz). Are you running the PC resolution on this mode? otherwise you can turn off the resolution warning by going into the monitor on-screen setup menu to turn off the resolution warning.

I have the same problem. I get a box with "not optimum mode. But what I need is a picture of the mainboard with the 50 ohm resistor between pin5 and pin6.



hello
I am a technician-informatic. I have repaired about 80 Lcd Samsung monitors with theese problems. I offer the repair manual.
Manual has been done with the experience of the repairing Samsung Lcd monitors. Manual was made by me and shows how to open monitor, how

to solve dark screen problem, how to check and replace capacitors, how to solve the problem non-optimal mode (without reprogramming MCU or
changing the main board) photo are included. 100% functional. The repair process is very simple 30-40min. (does not need a lot of
experience in electronics and expensive instruments) and is not expensive. With this manual you can solve problems by yourself and save
money.

"Not Optimum Mode 1280x1024 60Hz"
- The monitor turns on but turns off by itself, the LED blinks green.
- If you detach from the PC points to "control cable" the picture runs continuously in the vertical direction or presents while line , and
as soon as it is reconnected, the monitor goes off.
- The monitor does not turns on and dont dispaly anything, the LED blinks green-lit, if you detach from pc points to "control cable".
- The monitor turns on, works well some time, but after a window apiers "Not optimum mode. Mode recommended 1280X1024 60Hz"
- The monitor turns on, works well only with low resolution 800x600, when try to change a window that reads "Not optimum mode. Mode
recommended 1280X1024 60Hz"

the manual you can find on ebay (my ebay name is asnerejas123):

Cannot set my SAMSUNG SYNCMASTER 710V MONITOR RESOLUTION


When you can't change the screen resolution then most likely only the default VGA driver has been installed. You need to install the graphics driver of the video card that is installed in your computer.
To check which graphics driver is installed, click on Control Panel - Display - Settings - Advance - Adapter tab. If the graphics adapter is set for Standard VGA then the graphics driver was not installed.
