How to open display and replace inverter board in HP Compaq 8510p and 8510w notebook

4

In this guide I explain how to open the display panel and replace the screen inverter board in HP Compaq 8510p and 8510w notebooks. The inverter board located inside the display panel beneath the screen. The inverter board works as a power supply for the LCD backlight lamp. When inverter fails, the LCD screen goes dark. The image is still on the screen but you can barely see it.
By the way, in the previous post I explained how to remove the laptop motherboard.
OK, let’s start taking this unit apart.

STEP 1.
There are two rubber covers in the lower left and right corners of the screen bezel. You can remove these covers with a sharp object.


STEP 2.
Remove two torx screws found under covers. You’ll have to use a T8 torx screwdriver.
Attention! If you are looking for a good, reliable and unkillable screwdrivers, buy Wiha. You will never ever regret. Wiha screwdrivers are THE BEST! I purchased my screwdrivers over 4 years ago and I use them every day. They are still like new. Before that I was changing screwdrivers two times a month.

STEP 3.
Insert a piece of soft plastic (I use a guitar pick) between the bezel and LCD screen and slowly move it from left to right to release plastic latches securing the bezel.

STEP 4.
Continue removing the screen bezel with your fingers. Carefully separate bezel from the hinge cover.

STEP 5.
In order to access and replace the inverter board it’s not necessary to remove the bezel. All you have to do is lift up the bottom part of the bezel. You can see the inverter board located under the screen.

STEP 6.
Separate the inverter board from the display cover and unplug cables on both side of the inverter.

STEP 7.
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.
