Question about Samsung SyncMaster 710N 17" LCD Monitor

7 Answers

No display on SyncMaster 710N

I bought this display used. I can't get it to display anything from the computer. The monitor passes the self test with the signal cable disconnected from the computer; there is a floating "Check cable" box as there should be. But as soon as I connect the cable to the computer the check cable box goes away. The green pilot light at lower right goes off and on periodically. If I press the menu button on the monitor I get no OSD display, but sometimes I get a graphic box in the upper left corner saying Test Good with a graphic of five small circles with dots in the center, arranged as a row of 3 and a row of 2. None of the other buttons does anything except the power button seems to turn the green pilot light off and on. I'm on a Windows XP system on a laptop with dual display, and I have run other external monitors and projectors off it with no problem. I installed the monitor driver. It seems like the monitor can't read the sync signals from the computer. I'm using a brand new VGA signal cable. The computer can detect that a monitor is connected. The monitor detects when it is connected to the computer or not. Can anyone help?

    I tried the 50 Ohm resistor fix, but it did not fix the problem. I can read some Spanish, and the problem discussed in the dtforum series was not the same as mine. In that case the monitor displayed the message "not optimal resolution." In my case the screen stays blank except a brief message when I press the menu button, as described in my original post. I think the monitor does not read the sync signal coming in from the computer display card.

    Can you please tell me the type of this 50 Ohm resistor? Watt?

I used 2 resistor of 100 ohms (1/8W) to make one of 50 ohms. Like others instruction, just put the 50 ohms resistor between pins 5 and 6 of this chip and the problem is solved.

I tried 50oms(2x100oms, 1/4w), it worked for about one day and went back to original situation. Then, I found 4x218oms, 10w resistors, made a 55oms resistor. Now, the monitor works just fine.

I tried soldering a 50 ohm (actually it was a 47 Ohm resistor, 1/4 watt) between pins 5 and 6 on the Novatek IC and that seemed to have fixed the issue. I have been running the monitor for over an hour now with no problems.

Hi, i had the same problem with a same model monitor, the reason for this problem is a IC (IC200) in the main board on the monitor of course. The fix is cheap and easy, you just have to place a 50 Ohm resistor between pins 5 and 6 of this chip and the problem is solved. Here is the information (in spanish) i found, please give thanks to the autor, not to me!

    Well, my monitor had the same problem as yours and i fixed with the 50 Ohm resistor, first i installed a 75 Ohm and nothing happens, then i try with a 47 Ohm and was working for a short time and last i try with a 50 Ohm finally it works, but before that, i changed all power supply capacitors and fix all soldering, if that don´t works, well i guess and out of ideas!

I solved the problem by replacing the main IC board. Cost $40 and shipping. The monitor now works perfectly. If I had more time to fool around trying various resistances, or temporarily use a variable resistance for testing, I might have solved it cheaper. However, I'm satisfied.

Hy my monitor (710n) is having half picture scrambled. The lower part of screen is that the upper is ok. Like somebody cut it with the knife. Will the 50ohm tweak work for this?

SOURCE: NO DISPLAY :(

the resolution setting may have been in inadvertently change to one that your monitor does not support you mentioned that you have another monitor that does work with your computer what i would do is to set the video resolution to the lowest possible setting and the turn off the computer and connect the questionable monitor to your computer and reboot if it does come up then you will be able to make changes and find an appropriate resolution for your monitor

SOURCE: my syncmaster 710n is not working.

Not completely sure what you're saying. Here's what I got out of your problem:

You have a Syncmaster 710n that displays a box saying the best resolution is _____ x _____, but your Syncmaster 710v doesn't show that message.

The main question I have to ask you is whether or not you see the screen or display behind the message on the Syncmaster 710n.

In either case, I doubt that this is a hardware problem. I also highly doubt that your monitor cannot be repaired. Try the following:

1) If you see the display/screen is showing behind the message box, this is almost definitely a setting issue. You need to press the menu button on your monitor and look for an option that says something like "display resolution message" or "ideal resolution message", or something else like that. Then you need to change the setting for that option, for example if "Yes" is selected, then you need to change it to "No" or if "Enable" is selected you need to change it to "Disable".

If you have the manual for the monitor, it should make it easier to know what setting to change. If not then go here:

http://www.samsung.com/us/support/detail/supportPrdDetail.do?menu=SP01&prd_ia_cd=05020100&prd_mdl_cd=&prd_mdl_name=710N&prd_ia_sub_class_cd=P

and download the Manual that you need.

2) If nothing is being displayed behind the message, try to change the display settings of your computer. While using a different monitor, try the following: If in XP, right-click on the desktop and go to Properties, and select the tab for display settings and adjust the resolution to something compatible with your monitor (like the one it suggests you to change it to). If in Vista/7, right-click the desktop and select Screen Resolution/Display Settings and adjust it there.

Good luck. Let us know how it goes.

On dell 2405fpw, the screen just went black. Unable to select VGA input. Unable to perform self test.


You need to power cycle your LCD moniter, and then disconnect the display cable of your LCD from your system and see if yor LCD is doing the self test, if that is passing the self test that means there is nothing wrong with your LCD you need to check your system espeacially display adaptor and the drivers, you can also cross check if you have any other monuiter at home.

If your LCD moniter does not pass the self test then it means it has crashed you need to get it repaired or get the new one.

My monitor is brighter on the lower left side than on the rest of the display?


Hi,

NOTE : steps below are only for a Dell monitor
There could be two reasons for the same,
1. The monitor settings are bad or
2. The monitor has gone bad.

Request you to disconnect the monitor signal cable from the back of the computer (cable with the blue jack)

A self test feature check would run on the screen. If the screen is bright in the feature check . The monitor has gone bad and needs a replacement.

If the screen appears ok in the self test . Press the menu button on the monitor and select factory reset.

Thanks

I switched it on and begins to flicker and even with noise


1)Restore Monitor to factory settings using Menu buttons.

2)Perform Monitor self test

Turn the monitor off and disconnect the video cable from the computer. Turn the monitor back on.


If self test is displayed on screen without any issues, Monitor works fine
OR
Monitor gone bad
