If the screen is all white light then you can have a number of problems.
One could be a bad video board, the next could be a simple loose wire from the video board to the back of the lcd screen OR a simple blown fuse on the back of the actual lcd screen can cause the same thing.
Snaps are all sround these things and can be really stubborn at times. Best to start the bottom first then work up each side to the top.
Something flat, thin and with a decent sharp edge on it will help. A pocket knife held parallel to the joint between the front and rear plastic works, you can also sharpen the edge of an old credit card with a file (nail file works) This isn't as strong as a blade , but safer if you slip !!

Resolder L781 on the powerboard from the backside. Typically L781 is glued to board with white adhesive. Remove the old solder and scrape off some of the wire's lacquer finish for good contact.

This is a known issue.

White screen


The white screen you are getting is it just right after turning on the computer? If yes it means that you were not able to see the Dell logo correct?

Try connecting an external monitor thru VGA. While monitor and laptop is on with white screen please do this. Hold down Fn key then press F8 at the same time. This will toggle the display from the laptop to external monitor. If laptop displays to external monitor means that laptop LCD needs to be replaced.

If you do not have an external monitor try this.
While laptop is OFF. Do this. Hold down the D key then press power button at the same time.
Check if the laptop will display colors the whole screen. If you still see white screen then LCD needs replacement.

LCD mean LCD panel or the whole screen together with LCD cable and Inverter.

Hope this helps.

My dell E151fpb 15' monitor screen turns white


Look for loose connection between the LCD panel T-CON board and the logic board first, it may also have lost the 5vdc for the T-CON board.
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, 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.

Dell E151FPb 15" LCD with power LED blinking.


The problem may be a loose connection. When I turn on my monitor, the green light blinks and a flickering white screen appears for a brief second every time. There must be a loose connection on the power board which may be causing this. The easiest solution is to tap at the back of the monitor. This will reconnect the loose end and the monitor will work fine until it gets disconnected again. I will open my monitor soon to find the real problem. But it will take some time to find it.

Wacko Dell E151FPB


that sounds like a computer problem, not a monitor problem.  Plug the 'old' monitor in and see if your computer will boot with it.

Lcd monitor goes white


The E151FPb's seem to have a problem of this sort. After doing some research online I've found that the most common problem is a few dry solder joints on the large circuit board inside the monitor. There was also some talk of a connector suffering from heat creep that sound be connected better on the inside, but usually that would make the screen turn black if it were to become disconnected. The monitor can be opened by unscrewing all the screws on the back, there should be 6 screws you need to pull out before being able to open the case. After those, insert a thin, but strong piece of metal into the side and sort of twist/slide it along the side and it should pop open some clips and just work your way around the perimeter. After that it's just some simple and obvious screws to get to the circuit boards.
