Is your LCD Screen damaged? Are you planning to replace it? But be careful while choosing the LCD Screen for your laptop. The most accurate way to find a LCD Screen for your laptop is to use the original manufacturer (OEM) part number directly off the back of your laptop’s LCD Screen. For this you have to be able to remove your laptop’s LCD Screen.

Here are few steps that will tell you how to remove laptop LCD screens all by you.

  1. Firstly you have to make preparations and have all the tools ready. Unplug and remove the battery. Get a sharp pointed instrument (something like a thumbtack) and small Philips screwdriver with you all the time.
  2. Next inspect and located the screws which are usually covered by rubber screw covers. They may be in the front or on the side of the plastic bezel depending upon your laptop model. Remove the rubber covers with the pointed instrument (thumbtack) and using the Philips screwdriver remove all of the screws. Place the screws in a container, in case they might get lost.
  3. After you have all the screws removed, remove the bezel slowly. If it’s still difficult check if there are any screws left. Unsnap the bottom corners too (for this lean the display assembly as far back as it goes). If you can’t get your fingers between the bezel and the LCD screen, then probably this is because there is a protective screen attached to the bezel. For this you need to force-open off the bezel/protective screen assembly.
  4. Next just calm down and analyze the situation. See what’s left after the bezel is removed. You must see that the LCD screen is held by a metal frame which is again attached to the rear bezel by two brackets each secured by 2 Phillips screws. In the bottom you video cable and the inverter is partially seen.
  5. Now lift the LCD screen assembly along with the frame and brackets carefully (just enough to access the 2 screws which might be on the side of facing you) and unscrew the frame screws. Once they are all removed, bring the entire display upright to 90 degree and bring the LCD screen forward and lay it on the keyboard. Before that place a paper towel or a piece of cloth on the keyboard just for protection.
  6. Again take a moment to look carefully and understand the back of the LCD Screen. The video cable is going diagonally across the back and the inverter is between the LCD screen and the rear plastic assembly.
  7. Disconnect the video cable from the LCD video connector. If there’s any tape holding the video cable, take it off too. Then disconnect the inverter plug from the inverter. In some cases you might need to unscrew the inverter to get the connection. Also, there may be another connection (a digitizer) too that you may need to disconnect. Check on it too.
  8. The final step is to record the OEM part number for the LCD screen manufacturer which is the main reason why we went through all the above processes. But this is the trickiest part as there may be more than one label present. Each manufacturer uses a specific pattern to begin their part number. Once you’ve found the full OEM no. use it to order the LCD Screen.

Here’s a list of some manufacturers and how they begin their part numbers:

  • Acer begins “L”
  • AU Optronics begins “B”
  • Chi Mei begins “N”
  • Chung Hwa begins “CLAA”
  • HannStar begins “HSD”
  • Hitachi begins “TX”
  • IBM / IDTech begins “IT” or “IA”
  • LG Philips begins “LP”
  • Matsushita begins “ED”
  • Mitsubishi begins “AA”
  • NEC begins “NL”
  • Quanta begins “QD”
  • Samsung begins “LT” or “LTN”
  • Sharp begins “LQ” or “LM”
  • Sanyo/Torisan begins “TM” or “LMJK”
  • Toshiba begins “LTM” or “LTD”
  • Unipac begins “UB”

Well, these steps work for most laptops. Some however may be very different for which you have to take help from the experts. Hope, this could be of any help.
