Monitor turning off

I brought home a flat panel from work that we no longer use. When it is turned on, you see the desktop for a brief second and then it goes black. If you turn off the monitor and turn it back on, you see it again for only a second before going black again. I have check the power supply and connections. I have tried it on different computers and with different power supplies and cables. What am I missing? Any ideas?

    It is a Dell flat screen monitor. It does not have a model # anywhere on it!

    I have the NEC 1760NX which is reputed to be the same thing. I have precisely the same problem. The display worked okay yesterday so I'm thinking it's a heat problem, although I took the case off and felt around :) and I can't find anything like that.

That is to say, my NEC monitor is supposed to be the same as the Neovo F-417. I just went in and tapped on many of the components on the backlight inverter (while the power switch was off - this display has a real power switch on the side) and then turned it on and now it's working. I suspect the specific problem with this specific display (or displays which are the same product with a different label) is actually a bad solder joint caused during the manufacturing process, and that the actual fix (mine's working right now but I don't trust it to continue doing so of course) is to reheat solder joints on the board. If we are lucky this bad joint is one of the ones for a component that mounts to a through-hole and not one of the SMT ICs.

You might wanna try the same as posted somewhere else in this forums and lower the screen brightness. I am in the same situation as you (although the screen stays on for 3 or 4 minutes).
if this doesn't work then I'll suggest you hit the screen reasonably hard on the floor (given that you didn't pay for the screen and it would have been discarded anyway) and see if it works... x

The monitor turns on for a brief second then turns off.

First, make sure both cables (power and video) are fully seated
Still have this issue?
Try using a different monitor and see if you have the same results.

Did this just happen? Was it working fine before and just started? Have you changed any settings? What type of monitor? USB2.0 or VGA 9 pin connect? CRT? Flat panel? Mac? PC? OS?


When you provide such little information, one will only receive such little help.

Screen come on then goes black

The most common problem. It is related to old backlight lamps. The best solution is to replace them, but if you don't care a lot about total brightness, you may simply replace faulty lamp with 27pF 3kV capacitor, soldered across the high-voltage connector. That would be equivalent load for the inverter.
First of all, you need to find which lamp causes that problem. Disconnect flat cable from the display so all backlight will go through the screen. Now, using that 27pF capacitor replace lamps one by one and check when the light will stay for longer time. Keep that configuration as temporary solution, but make sure you will isolate your capacitor well, 'cause there's about 1000 volts applied to it.
