SOURCE: nec 700 crt

Not a solution at all, but I'll post that I have a NEC MultiSync FE700 monitor that I purchased back in 2001, and have I been using the monitor since that time. Lately the monitor has been showing signs of 'acting up'. I read on the Internet that CRT monitors generally have a working life of about six years. It may be, depending on years of use, that the monitors are just reaching the end of their life.

SOURCE: NEC 1860nx. When owering up monitor, screen lights

The inverter board was made using lead free solder.... thank the Europeans for that. The larger components develop cracks on their solder joints after a few months of on time. Remove the inverter board. Use 15x magnification or better in bright light and you'll see the cracks on the ends of the large resistors. Apply fresh solder and you'll be good to go. You might run into resistors where you solder one end and they lift up... that means joints on both sides went bad. Son't kow how many more fixya's I'll answer w/o free access to the other responders?

The 12V ac adapter could be the bad one. I have seen it was bad before. I don't whether you have a second adapter to test. That is what I am guessing for now, it is adapter because I have seen it happened to my clients before.

A very dark blue screen on a laptop that otherwise appears to be "on" is a sign that the backlight on the screen portion of the computer may be burned out. You can test this by shining a flashlight on the screen. If you can see your desktop icons, the backlight is burnt out. Replacing a bad backlight is not a do-it-yourself task unless you are comfortable doing delicate electronic repairs and have the design schematics for your model in hand. Your safest course of action will always be to take the laptop to a professional repair depot. There is one alternative repair option available if you're not comfortable doing surgery and a trip to the repair shop is not in your budget. Replace the entire screen module, case and all.

Doing Surgery Yourself

1.Remove the battery from the laptop. With the laptop model schematics in front of you, use the small Phillips screwdriver to separate the monitor from the laptop base. The schematics will indicate how to uncover the monitor hinges and free the monitor. Handle the screen gently because it will still be tethered to the base by a group of wires.
2.Remove the plastic case covering the "power bar" on the upper part of the laptop keyboard base. Refer to the schematics to find the way to release this cover and lift it off the keyboard. You'll see a group of fine wires leading back to the monitor. Unplug this cable so the monitor is now free from the base.
3.Follow the schematics to remove the casing covering the monitor screen. Be forewarned that the design of a laptop monitor "under the hood" is complex and delicate. Don't force anything. Don't experiment. Take frequent photographs of each successful disassembly stage so you can have some hope of getting it all back together again correctly.
4.Find the slim fluorescent backlight instrument behind the glass layers of the screen. Unplug it from the tiny cable receptacles and remove it. Insert the fresh backlight fixture and reconnect it to the cable plug.
5.Restore the screen assembly and the casing using the schematics and your reference photographs. Plug the screen back into the laptop base at the power bar. Don't reattach the screen hinges to the base until after you have tested it by booting the laptop. If the test is successful, turn the laptop off and connect the screen to the base unit at the hinges.

Alternative Repair

1.Purchase an entire screen-and-case assembly for your laptop make and model. Many intact assemblies are available online for reasonable prices. You will usually pay slightly less for an entire screen-and-case unit than you would for a professional repair on just the backlight alone so this could be an economical alternative for you. You can save even more money by purchasing as "Used but Good" unit, rather than a new unit.
2.Remove your old screen following the previous section's Step 1 through Step 3.
3.Plug the new screen-and-case unit into the laptop base. Follow the schematics and your photographs and thread the monitor wires through the hinge passes. Restore the power bar cover.
4.Test your replacement repair by booting the laptop. If the screen looks normal, shut off the laptop and reattach the new screen to the base at the hinges. Restore the hinge covers.

I hope you find it very helpful. Thanks.

HI, I have a NEC monitor 1760nx, dark blotches on the screen

Listen, for what it is going to cost you to fix the unit, you are better off replacing it and having a new warranty to boot. Simply not cost effective to repair given the cost of a new monitor these days.

My ViewSonic computer monitor keeps displaying a Vga Not Support Message upon booting then the message Out Of Range comes up on a completely dark screen. Need Help

It sounds like the computer is trying to use a resolution that the monitor cannot handle. Boot into safe mode by pressing the f8 key during boot up and select safe mode. Once booted, right click on the desktop and select properties. In settings lower the resolution by moving the bar to the left and reboot.

I would move it all the way down, you can then move it up a step at a time once you are in normal mode again.

Hope this helps
