    This monitor was removed from a system at work, after it failed.

    the monitor is bad and I believe the problem to be somewhere in the tha main power board.

    I got another one just like it about a year ago and its problem was three under rated caps on the power board, I was hopeing this would be the same, but it is a different power board design.



    any help would be great.

    Thanks

Have you tried another monitor with the computer to make sure you have signal coming out? If you have missing or corrupt video drivers in the computer or have memory seated on the motherboard incorrectly it will cause the same symptoms. If you have checked all these before now, disregard this.
I know that monitors do go out, but rarely. 90% of the time , it's not getting a signal from the computer due to a freeze from hardware or computer driver issue.

    Prolly more than one suspect capacitor and possibly a protection diode, also check for cold solder joints around the main caps on the power supply.

Where is the on/off switch?


Switching the power

If the OSD is active, press Auto to exit a selection in the OSD. If the OSD is
inactive, press Auto and the monitor will automatically optimize the
position, focus, and clock of your display.

If the led does not light up at all then either the power lead is faulty or there is no power in the power board.

How do i factory reset my NEC LCD1712 Monitor?


Here's some tricks I would try...
1. Verify the monitor's power cord is plugged firmly into the wall outlet and the back of the monitor.
2. Verify the monitor cable is firmly connected to the computer and the monitor.
3. Verify that you have turned the monitor power switch on.
4. If the power light on the monitor is not on, test the wall outlet (plug in a light or something you know works).
5. If the power light on the monitor is not on, try a different power cord.
6. If the power light is on and yellow or orange or flashing, but nothing displays, or the display is incorrect, borrow a monitor from a friend. If that works, your monitor probably needs replaced.
7. Also, you could try your display on a friend's computer. If it doesn't work, your monitor probably needs replaced. If it works properly on your friends computer, the problem may be with your computers video output port, motherboard video chip (or video card, if you have one), or drivers.
Good luck.

To get monitor work for you, you should connect the VGA cable to CPU. When you remove the VGA cable, monitor has got nothing to display so it goes in stand by mode with orange LED on.

Sir Help me with my Compaq monitor MV520 it won't turn the power led flashing orange to green continously


it could be th epower supply and it could be the monitor.
power ON button should not flash orange regardless what you do. it should stay green. then orange. not orange to green to orange.
try the monitor on another PC if you can fine one.
the other thing is are the 2 monitor similar (CRT to CRT and LCD to LCD), you can't mix the the two, they will work but need different video driver to function correctly.
