My 43inch nec plasma, will not pick up an incoming signal. it switches on (blank screen), but after around 20 seconds, it goes to standby.

It's going into standby because it's not receiving anything on another end for a set period of time. Be sure to check certain aspects of the monitor if you are connecting it to a PC.
Check if the PC is on first. Obvious, but youd be surprised. Make sure both cables are connected firmly and securely. Also make sure you're using the right cables. If the monitor has multiple inputs, try toggling through them If it still doesn't work, check if the computer is outputting signal on another monitor.
Hope some of these tips help

I have 2 of these monitors with the same problem. On power up the green led will light & remain on but the screen remains black. On one of the monitors the screen will light up for a few seconds then...

The inverter that turns on the back light may be bad - it's suppose to create the high voltage pulses to fire the CCFL back light lamps. Apparently the back light turns on after a few seconds however, it cannot stay on because the inverter might be bad. If you connect a known external CCFL lamp to the to the inverter output you can isolate the inverter.

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.

Monitor goes blank less than a second after turning on.

I start my computer and turn it on, and everything looks fine for about 1/4 of a second and then it goes black while leaving the power light green. I can only see the screen again after turning it off and on, but that's only for another 1/4 second. What's up?
I got my rosewill flatscreen as a hand me down from my father. I've had it for several years now. Was working fine until a month ago. When I turn the computer on the screen goes black after 1/4 of a saecond. I have to turn it off and on anywhere from 10 to 20 times before it stays on. I have checked all plugs to the computer and outlets. I have absolutely no idea whats causing this.

DiamondPoint V71LCD Not displaying image

The LCD screen may be burned out. There's whats called an invertor board and there is an electronic ribbon strip on the LCD itself. If you look very carefully you can probably see a faint image on the screen. The LCD screen will need replacing. Before doing anything with this monitor, try it on another computer first and if you can try another monitor on your computer. Other than that, there really is nothing you can do but replace the monitor.
