LCD error
My Dell inspiron 15 3542 was running fine. I used it for 10 15 minutes and then its screen went white and flickering. I went to a local store and the technician told me that my screen has malfunctioned and they need to change it. I want to know how my screen can just go white while I use it without any damage . They checked the display cable , it worked fine. Just the display was wrecked.
I press the power button and all I can see is this white vertical lines. Can you please elaborate a little more how to repair this?
The technician applied another screen to check the screen. The other screen worked fine when he powered the laptop.
Does that mean the screen is faulty or is it still the control board?

That's usually a control board failure, and these can happen suddenly.
If the system shows the same fault through a screen test -- hold D through powerup to access -- it does need to be replaced.
