Question about Samsung SyncMaster 710N 17" LCD Monitor

2 Answers

Monitor works for about 30 mins then goes blank with a messahe reading 'Not Optimum'

I've had this screen for over a year now and just of lately it's been turning itself off. The computer (which is a mac) still works but it goes to a black screen then I get a flashing message come up which reads something like 'Not Optimum' then it says 1260x680 or something along those lines. I've tried changing the resolution in the systems preferences and tried changing the screen saver to a basic one (as it seems to go blank if the computer lies dormant). Don't know if anyone's experienced the same thing? Cheers, Rick

    Our monitor stays on for about 20 minutes before blacking out. It needs to rest for about 5 min and will turn back on.

Hi Rick I have the same problem. Have you found a solution yet? I had the power supply tested, that is not the problem. It seems to go off when it gets hot. If I point a fan at it, it seems to last longer before blacking out. Pete

Screen turns on lights light up then after about 30 mins screen goes blank AOC PD4262

have you tried testing the screen on other pc if it wotks or the same effect? if you tried it on other pc and the result is the same, the screen or monitor is faulty,and needs repair or replacement, but if it works on other pc's, your pc have the problems. it could be the memory module, video card, or the motherboard or processor. also, try checking the settings, maybe you have set it to auto-off after 30 mins or so.

Turn on notebook (A200 2 years old). Runs fine for about 10 minutes then screen goes blank. if you plug in an external monitor both screens work. This is not an intermittent problem.

Have you check screen power down could be it is setup to shut down as you say after 10 mins. Access power through control panel, change settings ie to 30 mins

Samsung 713N screen goes black

1 Answer

Screen goes black after 30 mins of working.

There are a few things you need to check here.
1. It could be that your computer power management is set to turn your monitor and harddrive off after 30 to 45 min.

If the computer is however working for 30 to 45 min while you doing stuff and it shuts off, the there is an internal problem "Hardware"

I would suggest you check to see if the power management is set to turn off monitor 30 min and harddrive after 45 min. IF that is not so, then we go on to the next test.

It could possibly be your processor fan is not working so once your processor gets over heated it shuts off the computer.

Turn off the computer, remove the case "this is only if you know what you are doing" with the case off, power on the computer and see if the processor fan is working.

You can get back to me and I can walk you through it.

Hope thiss help.

New Samsung monitor returns only a blank screen when turned on. what can I do?

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

"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):

CRT Monitor goes blank

Have you checked your energy saving settings? Try to set the monitor to "always on" and verfy if the problem still persists.
Also check if your monitor drivers have their own energysaving options, although i doubt it.
