I have a Dell Inspiron 1545 that is running Windows 7.
Recently, the display has been starting to freak out and get thin horizontal lines all over the screen. Sometimes it helps to adjust the screen angle, but sometimes that also makes it worse. After it has been like this for awhile the screen turns completely white. I can still do things and hear sound from the computer while the lines are there, but the screen appears frozen. If the screen goes back to normal then the changes I made appear. I hooked it up to an external monitor and it the lines didn't appear on there.
I was wondering what exactly is wrong with the computer, and how much will it cost to fix it?
Thank you for your time reading this
Try reseating both ends of the cable that runs between the mainboard and display. If that doesn't fix the problem, replace the cable - and if that doesn't fix the problem, replace the display panel.
