Toshiba Satellite L855-S5119 Laptop Screen Replacement

Step 1 Back Plate Removal




• Turn the laptop over to place it top down.
• Use a Phillips #1 screwdriver to remove the screw holding in the back plate. This screw does not come out of the plate.
• Lift the back plate off the laptop, exposing the RAM and Hard Disk.
Step 2 Battery

• Turn the laptop face down to expose the back.
• Locate the battery.
Step 3
• Locate the battery latches. The battery latch mechanism can be compared to a door -- The right latch, when pushed right, unlocks the battery, while the left latch, when pushed left, releases the battery, pushing it out from its container.
• Push the latch on the right to the right to unlock the battery latch locking mechanism.
• Push the battery latch on the left to the left to unlock the battery.
Step 4
• With the left battery latch pushed left, remove the battery from its port by lifting the battery from the middle of the battery.
• The battery will come free.
Step 5 Optical Drive
• Using a Phillips #0 screwdriver, remove the single 3mm screw.
Step 6
• Rotate the laptop so that you have access to the optical drive.
• The optical drive is now only attached by a port in the drive's back. The optical drive can be pulled straight out of its housing.
• Remove the drive.
Step 7 Hard Drive
• Unscrew the hard drive.
• There could be up to five 3mm screws - One on each corner of the hard drive, and one at one end of the hard drive, attaching the drive to the laptop's frame.
• Carefully push the hard drive away from its port. This should not require substantial force.
• Lift the hard drive out.
• Some hard drives have a plastic tab, which can be lifted from to remove the hard drive.
• Otherwise, take hold of opposite sides of the hard drive and lift the drive straight up.
Step 8 Back Cover Removal
• Unscrew the screws circled in red. This includes eleven 6mm screws, and one 5mm screw underneath where the optical drive was housed. All screws can be removed with a Phillips #0 screwdriver.
• Carefully remove the back cover. The battery holder contains notches that help hold the case in place, so take care not to break those.
Step 9 Fan
• Remove the two 5mm screws on the fan assembly using a Phillips #0 screwdriver.
Step 10
• Unplug the fan's connection to the motherboard.
• Lift the fan from the laptop.
• Use a soft cloth to clean the dust away from where the fan was.
Step 11 Laptop Screen
• Remove the two screws in each speaker using the Phillips #0 Screwdriver.
• Gently lift out the speakers out of the chassis.
Step 12
• Using the Phillips #0 screwdriver, remove the 3mm retention screw from the display connector.
• Unplug and remove the display connector by pulling the connector free.
Step 13
• Remove the screen by removing two screws from both hinges using the #0 Phillips screwdriver.
• Once the hinges have been unscrewed separate the screen from the body containing the motherboard.
Step 14
• The removed laptop screen should have the daughterboard and speakers attached to it via wires upon removal.
