Nec lcd2080uxi, monitor power light comes on green but no video is being displayed, screen stays blank , cannot get into the built in setup selections. nothing is being displayed on the screen


Power supply or backlight inverter problems, those are the two areas you need to check.
If you are going to DIY and have proper tools and know safety precaution then please read on:
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, blown fuses; poor solder joints, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

Not really that tough. Sounds as though the backlight is shutting down, either from a power supply failure, or a failure of the backlight circuit itself. You can verify this by holding a flashlight to the screen in the area where the menu usually appears to see if it displayed on the LCD panel with no backlight. If you can faintly see the menu displayed, your backlight has shut down and the most likely cause is the backlight inverter board, followed by the power supply and the backlights themselves which are part of the LCD panel. If you found this information answered your questions, please be sure to rate it. Thanks!

NEC MobilePro 780 Screen


A couple of things spring to mind. Have a good hard look at the screen when it goes dark. Is there still an image there but it is really dark? If so, consider that it may be a faulty backlight. It may also be a faulty ribbon cable joining the screen to the main unit, or it may be that the brightness down button is stuck and causing it to lower the brightness. The fact that you are pressing the brighness (up button I am guessing) and it comes back on, may indicate the bright down button is stuck or by pure chance you are pressurising the board in that area causing a bad contact to work, such as power to the backlight or pressure on the ribbon cable. I dont have one of these MobilePro's but I am just going on things I have seen with notebook PC repairs. Hope this helps.

My monitor not stay on


Very common for this model that top backlight globe goes faulty. Can be also inverter PCB fault. If you have couple spare lights connect them to your inverter instead of panel lights and see if fault remains.

Problem with plasma tv


Something in the path to drive the other half of the screen has failed or is broken. Need some basic troubleshooting information in order to be any more specific, but I've seen this problem before with NEC plasmas. If still under warranty better use it Good luck
