HP G6 Backlight issue

[Banana_Molester]

Hi, I found my mom old Laptop and wish to use it as a Linux machine to learn about it.

The problem is the backlight it doesn't work. I can boot into windows and if I use my flashlight from my phone I can see an image.
Here my troubleshooting step.

Tried 6 Different display 2 From other HP laptop that has Motherboard failure one that a had that was compatible. I've changed the led cable Still nothing.
I've removed the motherboard and inspect it to see if any thing was wrong and nothing.

I just ordered a power button thinking it could be the LID Switch.(Waiting for it)

Product: QA080UA#ABC
Model: g6-1b37ca

Hi

Welcome to HP Forums, 

This is a great place to get support, find answers and tips, 

Thank you for posting your query, I'll be more than glad to help you out 🙂 

As I understand your HP Pavilion G6 notebook has a back light failure,

Don't worry as I'll be glad to help, however, to provide an accurate resolution, I need a few more details: 

Did you know that the back-light failure such as dim display or displayed that's only visible with the help of a flashlight is related to the inverter board/display assembly?

That said, before concluding this as a hardware failure, I recommend you try these steps as well: Click here for instructions,

If the issue persists, I suggest you confirm the part number on the HP Parts Surfer and order it either via HP Parts Store or at any local retailer as the part numbers are universal.

Let me know if those steps worked for you,

If they did, that's awesome!
