Today I show how to replace cracked LCD screen on Dell Inspiron 1545 laptop. The procedure is very similar to replacing LCD screen on many other Dell laptops and takes about 30 minutes.
Dell Inspiron 1545 laptop uses two different types of LCD screens:
1. Old style LCD screen with CCFL backlight.
2. Newer style LCD screen with LED backlight.
In my case I’m replacing LCD screen with LED backlight.
Update: if you need to take apart the laptop body, check out my complete Dell Inspiron 1545 disassembly guide
Before you start, make sure the laptop is turned off and battery removed.
The screen bezel has six rubber screw covers.
Remove all covers with a sharp object.
Glue these covers somewhere on the screen bezel so they don’t get lost.
Remove all six screws found under those covers.
Insert your fingers between the bezel and screen and start separating the bezel.
The screen bezel secured by hidden latches. You’ll have to wiggle the bezel in order to disengage those latches.
Continue separating the bezel on the top of the display assembly.
The bottom part of the bezel could be glued to the LCD screen with sticky tape.
In this case insert a piece of soft plastic (I’m using a guitar pick) between the bezel and LCD screen and carefully move it along the side.
The LCD screen bezel has been removed.
Remove two screws securing LCD screen to the display cover.
Separate LCD screen from the display cover and place it face down on the keyboard.
Now you can access the video cable connector on the back of the screen.
Laptops with LED backlit LCD screens have no inverter board. There is only one cable plugged into the screen as it shown on the following picture.
If you are working on a laptop with CCFL backlit LCD screen, you’ll have to disconnect video cable from the LCD screen and inverter board which is located on the bottom of the screen.
Remove sticky tape securing the connection.
Unplug video cable from the LCD screen.
Now you can remove the LCD screen and replace it with a new one.
You can search by the LCD screen model number which is printed on the screen label. In my case I had this screen: LP156WH2 (TL)(A1).
Remember, there are two different types of screens used in this model: LCD screen with CCFL backlight (older type) and LCD screen with LED backlight (newer type).
CCFL backlit LCD screen have a short cable sticking out of the lower right corner – this is backlight lamp cable.
LED backlight LCD screens do not have this cable.
Make sure to buy the correct screen.
The final step would be moving LCD screen mounting brackets to the new screen.
Remove three screws on one side of the screen and transfer the bracket to the new screen. Do the same on the other side.
