You need to check the power supply/inverter board caps, voltages, etc. I hope it isnot the lamp problem as shown in my pictures here:

If you are going to DIY and have proper tools and know safety precaution then please read on:
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply (they should be replaced in a set), blown fuses; poor solder joints, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

My HP Compaq laptop nw9440 screen gives me white tin lines whenever I powered it on and don't display anything ,I tried removing the memory but still nothing happened


The memory has nothing to do with the display. Most likely it is the inverter board. For the display. They are not expensive an can be put in easily if you can solder. Take it to a repair place an let them look at it to make sure. I have seen the screen fail from crumbs an dirty contacts.

The screen replacement is defective or the part number is wrong, check the part number on the back of the original screen and compare it against the the one you replaced, it should match.

Monitor went out and only displays a black screen. The power button indicates that the power is on but no picture. The model is an HP f1905 19 inch flat screen monitor.


Use a flashlight and shine on your screen. Look carefully is you still see the image on the screen. If you do, this is an indication that the monitor is still working, but the backlight has failed. A common solution with backlight-failures is to open the monitor, and look if you see any "swollen" capacitors (http://en.wikipedia.org/wiki/Capacitor_plague). If you see one you should replace it. Only open your monitor if you know what you're doing and have basic knowledge of electronics and soldering.

Pleasec look through my albums so you will know what to look for.

Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps).

HP L1720 flickering!


this is common, the display is bad.
all displays, fail. all do. no reason to get angry,
a broken display is worth nearly zero value $0
so how much money will you spend on worthless.?
you can get a new display at Walmart for $65, ,
lines are usually very serious. and is not ever the DC-DC inverter
a bad inverter (< it's power supply) is for the back ground lamps. not data side. the data side is failing and is common, if you twist the screen
it gets worse. ? bingo. data driver connections bad , screen.
IN most cases the part that is bad (screen), costs $100 new. or 50 used
why go there/
?
