Question about Dell UltraSharp 1800FP 18.1" LCD Flat Panel Monitor

1 Answer

Dell UltraSharp 1800FP is black on start up but green light is on

Every day when i turn on my computer and monitor, the monitor stays black, but the green light turns on. I have to unplug the power cable and plug it back in a few times before it starts to work. When its doing this, the power button in the front doesn't work either, any ideas what the problem might be?

    I now have this problem with my 1800FP after a power outage last night while the monitor was on. I have the monitor on a (cheap) surge protector, but the breaker didn't even trip. Now, no matter what I do, the green power light stays on, but the screen is blank. I have tried unplugging the power and video cables in different combinations, but still no luck. Is it likely that the power outage fried something? Thanks!

    I have a similar problem with the 1800FP monitor. when i boot the computer the monitor flashes the box that says "DSUB power saving" mode and then goes into perpetual sleep mode, with the LED indicator remaining yellow.



    When I initally booted the monitor, it worked for a few minutes, then I pressed to see the menu (to adjust the colors) and it stopped working.



    any thoughts on what the issue might be?

SOURCE: dell ultrasharp blinks on and off

It could be a setting problem, power saver setting, or a mode that the monitor does not really support - things like refresh rate - or actual hardware.

Easiest way is to borrow another like monitor, and say another video cord and see if the problem remains, or if a newer monitor says 'out of range' or similar.

Then, if you have a fancy video card,remove it and use something primitive. Not reading instructions is a big cause.

If its not a setting issue, and as the inverter board is ok; if the above description is correct, reseat the inner board connecting cables.(wood fires and seaside locations) If not that, a lucky guess might be the electros on the logic board.

SOURCE: my dell ultrasharp 1800fp monitor keeps flashing

Inside there is a IC chip on the power pack that goes bad, replacement is called for also look for bad capacitors when you are inside looking around, those need to be replaced as well
hope this clears things up. dells third party who built these units did a rotten job on this model. that chip always fails.

Most likely, this is failing "inverter."
The backlight of the monitor (that makes the image visible) is controller by a special chunk of electronics called an inverter. They tend to fail over time. The symptom is that the backlight either never comes on, flickers, or shuts off after a short period of time.
It is a moderately advanced repair job to change out the inverter, but you can usually get the part on eBay. Search for the exact monitor model number and "inverter".
The 2001FP has six lamps and the inverter is fairly expensive. You might be better off putting that money towards a newer monitor.

My Dell 1800FP monitor went black


Confirm your cables did not work themselves loose. Try using a different power cable to confirm that it was not the cable. Finally try a lamp in the socket you are using for the monitor power cable, if you are not using a power bar but even then just to rule that out. If the only thing left is that your monitor is dead, you will need to recycle that one and purchase yourself another one. Sorry
