How to Fix a Acer Aspire 7520 Keyboard Monitor

[laptopkeyboard]

A laptop display is one of the most expensive single parts to replace. It can be frightening to try to boot up your Acer Aspire 7520 one day and have it display only a white screen. Unless the screen itself has been broken, the cable between the laptop and the screen has either become disconnected or broken. This is a relatively cheap repair.

Disassembly
* 1

Disconnect the unit from AC power and remove the battery. This can be done by flipping the unit over, pressing the latch on the bottom of the unit and then pulling the battery away.
* 2

Remove the two screws revealed by removing the battery. Remove two additional screws set into the corners of the base on the edge where the battery was.
* 3

Turn the laptop over and open the lid. Remove the panel with the power button on it by gently pulling up from the top edge. Remove the Acer Aspire 7520 Keyboard by gently pulling at its top edge to release the four catches on the sides. Once it is free of the catches, flip the keyboard over and lay it down. If you wish, you can disconnect the ribbon cable leading to it and set the keyboard aside.
* 4

Unplug the video cable. The video cable is the thick wire coming out of the left hinge of the LCD. It is gray and rounded. The cable terminates in a rectangular plug that goes through the top of the laptop base.
* 5

Turn your attention to the LCD. Remove the rubber feet at each of the corners of the LCD. Remove the four screws that are revealed.
* 6

Pull the LCD bezel (the plastic part that surrounds the screen) away from the lid by starting at the top and pulling up and away from the inside with a rolling motion. The bezel is secured by plastic latches all around the outside, and pulling up with a rolling motion is the best way to get them to release without breaking. You can also take your blade or screwdriver and insert it between sections of separated lid and bezel to hold them apart and prevent re-latching. Be careful and patient with this step. Believe it or not, this is where the majority of laptop damage is likely to occur.
* 7

Remove the two cables connecting the inverter board to the LCD screen and the video cable.
* 8

Remove the four final screws holding the LCD panel into the lid. Two are at the bottom corners, just above and toward the center from the hinges. The other two are at the top center, holding the webcam and LCD to the lid. You should now be able to pull the LCD out of the lid and lay it face down on the base of the laptop.
* 9

Remove any tape securing the LCD cable gently, and then tug the cable out of its socket and set it aside.
Replacement and Reassembly
* 1

Begin by gently inserting the replacement video cable into the socket on the back of the LCD and re-securing the cable with the same tape from earlier. Lift the LCD back into the lid and screw the panel back into place. Finally, re-connect the two cables to the inverter board.
* 2

Press the bezel back into place with a firm, but not overwhelming, pressure. Each section should "click" when the latch engages and not separate again without effort. Replace the screws holding the bezel in place and then re-cover the screws with the rubber feet.
* 3

Plug the new video cable into the main board. Use a gentle and even pressure, making sure that everything is lined up. If you disconnected the Acer Aspire 7520 Keyboard, reconnect it and push it gently back into place until the catches reengage. Place the power-button panel back in place and press it down before closing the lid and flipping the laptop over.
* 4

Replace the four remaining screws and slide the battery back into place. Reconnect the laptop to AC power and turn it on. Your screen should now be functioning normally again!
