In this post I explain how to replace LCD screen in a Dell Studio 1555 laptop.
UPDATE: today I had to replace damaged screen in a Dell Studio 1558 laptop and the replacement procedure was identical to Dell Studio 1555.
In my case the LCD screen started showing horizontal lines and only small portion of the screen still worked properly.
In order to replace the LCD screen it’s not necessary to disassemble the entire laptop and remove the display panel. You can replace the screen while the display panel still attached to the laptop.
Before you start, make sure the laptop is turned off and battery removed.
There are no screws securing the screen bezel to the display cover. It’s secured by hidden plastic latches.
Insert a piece of soft plastic (I”m using a guitar pick) between the screen bezel and display cover and wiggle it to release hidden latches. Separate bezel from the cover.
Continue removing the bezel with your fingers.
Separate bezel from the cover on the bottom of the display assembly.
Remove the screen bezel.
You’ll find a small magnet attached to the back side of the screen bezel. This magnet activates lid close switch when the display is closed.
Do not lose the magnet or the lid close switch will not work.
Remove four screws securing the LCD screen.
Separate the LCD screen assembly from the display cover so you can access the webcam cable.
Unplug the cable from the webcam module.
Place the LCD screen face down on the top cover.
Remove sticky tape securing the video cable connector.
Unplug video cable from the LCD screen.
NOTE: if you have an older LCD screen with CCFL backlight, you’ll have to disconnect one more cable from the inverter board.
My Dell Studio 1555 laptop came with a LED-backlit LCD screen which doesn’t require the inverter board.
Remove LCD screen assembly from the laptop.
You’ll have to transfer mounting brackets to the new LCD screen.
Each mounting bracket secured by two screws on the side of the LCD screen.
You can search for a new replacement LCD screen by the screen model number or Dell part number.
In my laptop the LCD screen model number is BT156GW01 V.4 and Dell part number is 01G5D3.
Dell Studio 1555 laptop comes with a few different types of screens:
1. 15.6” WXGA (1366X768) HD screen with CCFL backlight.
2. 15.6″ WXGA (1366X768) HD LED-backlit LCD screen.
3. 15.6″ WXGA++ (1600×900) HD+ LED-backlit LCD screen.
4. 15.6″ WUXGA (1920×1080) Full HD LED-backlit LCD screen.
Make sure to find the right replacement screen for your laptop.
