Dell UltraSharp 2001FP (Gray) 20.1" LCD Monitor

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 monitor screen is coming on and off

Check the cable connections to make sure they are not loose. Do you see the image still on the screen when the light goes off? You might have a bad backlight inverter which would cause the light to flicker.

Sometimes the screen goes blank and today when I restarted the computer the screen is flickering very lightly.Does this means its going?


The picture board on your monitor is bad, since the power led or button is on and all connection are corrrect, it means the picture board of your monitor has developed fault.

The best thing for you to do now is to take the monitor to a local repairer within your vicinity to help with the replacement of the picture board because the fault is not something you can fix yourself, in order not to complicate issues.

Take care

LCD monitor very dark.

The fault may lie with the ccfl inverter which basically provides a high voltage to drive backlighting for the lcd display. Not sure where you can get this part other than Sharp, but look round on the internet on this subject. I successfully repaired a similar problem with a portable dvd player using a ccfl inverter normally used to modify pc base units with neon-type tubes. Cheaply available at Maplin electronics,but may be a bit large to fit inside the monitor? Could be fitted outside as the wiring is quite long enough?

Back light

I would suggest Tritronics for the service manual and the replacement parts. Unless you have a service manual, it takes a lot of disassembly by careful observation (or trial and error) to determine how that delicate LCD panel is put together! Of course I'd want to be sure that the problem is not in the inverter instead since that's a much more common cause of backlight trouble. Unless you happen to know it's one or more CCFLs, then of course you'd want to replace them all since they have the same aging.

Sharp LL T17A4-B (Black) 17 in.

Are you using the digital connection?? If so try using both the analog and digital connection then set the digital as the Main monitor in your graphics card interface. To check if the backlight is out, darken the room, and light a flash light into the screen. If you can see a picture, then you need to replace the backlight. Good luck
