In this guide I explain how to take apart the display panel and replace the inverter board in HP Compaq 8510p and 8510w notebooks.
The inverter board located inside the display panel below the LCD panel.
The inverter works as a power supply for the backlight lamp inside the LCD.
When inverter fails, the LCD goes dark. The image is still on the screen but you can barely see it.
OK, let’s start taking it apart.
There are two rubber covers in the lower left and right corners of the display bezel.
You can remove these covers with a sharp object.
Remove two torx screws found under covers. You’ll have to use a T8 torx screwdriver.
Insert a piece of soft plastic (I use a guitar pick) between the display bezel and screen and slowly move it from left to right to release plastic latches securing the bezel.
Continue removing the bezel with your fingers.
Carefully separate bezel from the hinge cover.
In order to access and replace the inverter board it’s not necessary to remove the bezel completely.
All you have to do is lift up the bottom part of the bezel. You can see the inverter board located on the lower part of the display assembly.
Separate the inverter board from the display cover and unplug cables on both side of the inverter.
The inverter board has been removed. Now you can replace it with a new one.
According to the HP maintenance and service guide for HP Compaq 8510p and 8510w notebooks, there is only one inverter listed for these models.
The part number is 452214-001. Google the part number and you’ll find it.
By the way, in the previous post I explained how to remove the motherboard.
