SOURCE: monitor power shuts off without warning

You might check the filter capacitor on the power supply and see if it is swelling or shorted.

SOURCE: nec multisync lcd 2080ux no raster no power indicator light.

If u a tech, try checking the PSU of the monitor for blown fuse or dead driver element ( typically a FET, Power transistor or an Hybrid chip) . U need to take the monitor apart, if unfamiliar, get it to a service tech.

SOURCE: touch system not working NEC multisync 1550v

You have to install the nec driver for this monitor. I have the same monitor. Im looking for the driver now. There are 2 versions of this monitor with the same model # . You will need to find the driver to the touchscreen model.

SOURCE: The resolution notifier keeps popping up (NEC

It probably is warning you that your video graphics adapator is puting out a non-native resolution to the monitor.

LCD monitors are designed for a specific resolution. If you don't use that resolution, the LCD has to try to mimick the resolution you've asked for.

Check your display settings and also consider updating your graphic driver if a new version is available.

Steady red status light on NEC VT45 projector. Would not POWER ON. LAMP was replaced with a new one


the power supply on that model seem to go bad after a while. the caps aren't properly reted it's power needs. they dry up. if you are good at soldering, replace c1 on the board (big cap) with a cap that has a slightly higher voltage rating. or replace the whole power supply. you might not be able to get one from nec, but you can try www.projectordoctor.com

Multisync LCD 1700V turns on then screen goes blank and shuts off


Does the power light stay on? If so, you have an inverter problem. If the power light goes off, you have a power supply problem.

NEC MultiSync VT540 not turning on - Temperature error


Hi
if the status light is blinking red in 4 sec interval it means that there is something wrong with cooling system. you shold check if there is a thermostat failure or if there are any switches that are not turned on. i suggest you to open the device (using screwdriver) and check if there are any switches broken or damaged.

i had pretty much the same problem (one second interval). i took off the cover and there was a broken switch and i just short-circuit it and now it works

Sorry for my english

Check to see if the fan is running on the bottom of the unit. If it senses no rpm from the fan, if will shut down to protect the unit.
