My laptop's wireless was not working, so I opened the monitor to check the wireless cables and receiver.

you did not reassemble it correctly

lcd's tend to have two thin and LONG strips of gray and black or black and white strips of CONDUCTIVE rubber

these make contact inside to the circuit board

i would co check out the website "I-Fixit "
https://www.ifixit.com/

for your brand
they also sell the REQUIRED and NEEDED tools for this type of work

Well it sounds like you un-seated the cable that send the picture to to the monitor. The reason you are only getting a white screen is that the back light is on but there is no data coming through to display.

The cable usually is a ribbon that fits into a slot. The slot then locks by pushing down on the cable and that makes the connection. It is easy to pull this cable out of the slot slightly (or all the way) and this will cause the problem that you are experiencing.

After more than a year, I wonder if OP still have the laptop with the bad display. If the built-in display does not work, you could try attaching the laptop to an external monitor. Many laptops will auto-detect the external monitor and automatically switch to using it.

I think your laptop should have one of following reason

    Loose connection between the video cable and the LCD screen.
    Defective LCD screen.
    Defective motherboard (I assume the graphics card is integrated into the motherboard).

The white screen means that your backlight is working. So it is not an issue. What you do not have is any data to your screen. Check the cable, the connector and start off by connecting an external monitor to your laptop. If that works you will know that the GPU and its circuitry is working.
