Your instincts are probably right about the problem not being the LCD itself. Besides color warping or seeing dead pixels/a patch of dead pixels the problem with the display most often comes from the inverter board inside the LCD case. So many people assume their LCD is bad if ANYTHING is wrong with it when that’s usually not the case. Since you are
using a Dell laptop it should be pretty easy to replace.
Remove the plastic covering for the LCD. This can be tricky if you haven’t done it before. It is connect with tiny little clamps on the inside so you have to be careful when removing it. On Dell computers you pull the plastic AWAY from the LCD itself so if you are working on the right edge of the screen you pull it RIGHT. On the top side you pull upwards, bottom
side downwards, etc.
The corners are very tricky and you just have to pull them diagonally away from the screen. You literally do put your fingers in the small area between the LCD and the plastic and slowly pull on it. If you have a plastic tool to pry it apart that’ll work too.
DO NOT USE SCREW DRIVERS OR ANY HARD EQUIPMENT FOR PRYING. The plastic is soft and will scratch or dent easily. Only use plastic devices to pry it open if you need to use something other than your fingers.
On most models the inverter board is on the bottom of the LCD (on Dells it is usually on the bottom right corner). It will be connected with one or two wires that easily pull out. There may be a screw or two holding the inverter board in. Simply remove those, remove the cables and it’ll pop right out. Replace it with a good board and reverse the steps to put it back together.
If the computer is under warranty they will send the inverter board for you. Sometimes they prefer to send the entire LCD kit (inverter board + LCD screen + plastic covering) and ask you to replace everything and send back the old parts.
