How to connect a univerasl XB LED kit to an  existing Laptop inverter wire harness

This section is to show you how to wire XB LED converter (XB Universal LED kit) to the existing Laptop inverter wire harness.
Remove front bezel and then you will see an inverter is located at the bottom of Laptop screen
Remove the screws and pull out an inverter as shwon photo below
To identify the pin assignment:*

Fuse=VIN. First look for SMD Fuse (Surface mount fuse). This fuse is a small and think component. Some of inverter also has a print on PCB next (or at the bottom of PCB) to the fuse, such as F1 or F101.

Second, look for a large solder pad or large cooper pad. These are the indications of power ground (GND). You can also confirm with a multi meter, set your meter on resistor range, connect one of test probe (It does matter black or red probe) to any metal part of Laptop screen, if the resistance is 0 ohm, then it is a GND Third, connect other pins that you are not sure to either ENA or ADJ. If the LED backlight does not light up when Laptop computer is on, then just reverse these twp pins.

*Note: If you know how to use a multi meter to measure input voltage, It is much easier to identify these pin assignment. Please click here for details.
If you need an additional help, Please email us two pictures. Top and Bottom on inverter's Input connector to techsupport@lcdparts.net
By now, we had identified the pin assignment, next we need to solder the wire to an inverter. Since you are upgrading to LED backlight, the existing inverter is no longer need, so we can convert it as an “Wire Adapter”. Cut it off as shown photo below
It depends on the space right below laptop screen. However, I would suggest that you trim MS202CN down to about 2”
Solder wires on Inverter's connector according to its pin assignment that we had identified
Connect XB LED kit to Laptop computer and turn it on. All LED should be light up. Now it is ready to install XB LED inside of Laptop screen.
