  blacks out. 
• An image is still visible on the screen but it’s very
  dim. 
• Sometimes the backlight works and fails repeatedly or
  occasionally.

  backlight never comes on but and image is barely visible on the LCD
  screen.

How do I install an LCD inverter?

    Most laptops are going to be very
different with their LCD inverter installations. Some just require
opening a small compartment above the keyboard, while others require
taking off the LCD screen itself. You will always need a small
screwdriver to work on the tiny screws throughout the laptop. Also, the
full manual to your laptop usually helps as it conatins diagrams on
where to unscrew/unhook laptop components.

How do I find a replacement LCD inverter board?

    When shopping for an LCD inverter, there
are a few things to look for. You must note your laptop’s model. Not
only do you need the brand, but you also will need the specific model
for your LCD inverter. (For instance, Dell
E1505 LCD inverter) You can also look on your inverter, and
there will be a group of white text that will state the inverter’s part
number. You can try searching for that part number for a compatible
inverter. The last thing to note, is the connections on your inverter.
If you’re browsing online, compare the connections on your inverter to
the pictures of the store’s to see if they match. You can find LCD
inverters here.
