My computer is fine but when i wate my screen goes white

Very likely that the screen cable is damaged around hinge area. It has to be replaced. (just the cable, not the whole screen).

im only having a guess but i think it could be your ram is corrupt its known for the screen to go white when theres ram problems try taking out one of the sticks of ram and see does that sort it if not put that one back in and take out the other one if you only have one stick of ram then i would suggest bringing it to a store to get fixed it might not be any of these but its worth a try...look up youtube to see how to remove ram and dont remove it with the computer turned on and dont put it back in with the pc on either make sure its off and touch something metal before opening the pc to discharge any static...hope this helps

The new display is either an incompatible replacement or defective. Visible image material on the old display afterward proves that it is not a problem with the video cable, software or other hardware in your computer.

You need to have the inverter on the monitor replaced. You need to ask a computer technician to replace the inverter.
Hope this helps

have you got the screen output on 2nd monitor only ?
hold down windows key it is right next to FN key and press P
also you may have changed the settings to make the second screen the defeult screen . (not sure how to change this just remember seeing it as an option in settings)

When the screen glows grey/white, it means that the T-CON board is bad or it is not getting the 5vdc from the logic board. or loose conection on the T-CON board which is part of the LCD panel assembly.
Does it look like this when it goes out? Checkto see if the 5vdc goes away when it goes out, the 5vdc is supplied through the switched transistor on the logic board..

Take thhe battery out and dis connect all other power including phone wate 15 seconds and put the battery back in and reconect cables and phone. it should reset itself

2 questions do you press one of the function keys if you do it will do that and if you dont it is because of an so called "improper shutdown". what you want to do is simply move the arrow keys left or right brfore the menu. if that does not work press first safe mode wate along time and after just do start windows normly and wate along time

White screen is an indication of a faulty video board.
A blown fuse in the actual screen will cause the same effect but usually these do not reset on a fresh startup.
You can check the ribbon going from the video board to the back of the screen to see if it is somehow working loose, but I think based on your description that this isn't the problem.
