Levono IdeaPad Z575 screen broken



In this guide I explain how to remove and replace the LCD screen on a Lenovo IdeaPad Z575.

In my case the laptop was dropped and the LCD got cracked.

Most likely this guide will work not just IdeaPad Z575 model but for some other IdeaPad models too.

If this disassembly guide works for another model please mention the model number in the comments area after the guide.

Before you start make sure the computer is turned off and battery removed.

STEP 1.

Using a sharp object remove the screw cover from the lower left corner of the display bezel.

Remove left screw cover

STEP 2.

Remove one more screw cover from the lower right corner.

Remove right screw cover

STEP 3.

Remove screws found under those covers. You’ll have to use a small Phillips screwdriver for that.

Remove screws from screen bezel

STEP 4.

Insert your fingers under the display bezel and start separating it from the back cover.

Wiggle the bezel in order to unlock hidden latches.

STEP 5.

Continue separating the bezel on left and right sides for the display assembly.

After that move to the lower part.

On the back side you can access the web camera cable and video cable. They are bundled into one video harness.

  1. Hi, thanks for the help.
    I was using my compaq presario CQ61 when it suddenly went off. With the manner in which it went off, i thought it was a battery drain. But when subsequent attempts to power the laptop failed after making sure the charger was properly fixed to the power source, i thought the charger had gone bad. I replaced the charger but there was still no response from the computer. No lights at all.
    So i took off the battery, plugged the charger and tried to power the laptop. The laptop still didnt respond only i noticed that the small charging light at the point where i insert the charger comes up and then goes off after a few seconds (this happens only when the battery is out).
    Any suggestions as to what could be problem? Anyway i can further troubleshoot? I would appreciate your help.
    Thanks.
    Best regards.
    kels.

  2. I just replaced the LCD in my Thinkpad. When I turn it on, I get the IBM logo for about three seconds before the screen goes black. The computer still starts, but no backlight so I can’t see anything.

    Is it possible to connect the LCD properly but not the backlight? Might it just be the inverter? (It worked fine with the old broken LCD.) It is possible to have “connected it wrong” to where it goes out after 3 seconds?

    Thanks.

    @ Mugsy,

    I just replaced the LCD in my Thinkpad. When I turn it on, I get the IBM logo for about three seconds before the screen goes black. The computer still starts, but no backlight so I can’t see anything.

    It’s possible the replacement LCD screen has defective backlight lamp.
    You can try installing the old broken screen back in place and see if the backlight still works. If it does work, the new screen has defective backlight.
    If you have the same problem with the old cracked screen it’s possible the inverter failed.
