I have a HP Pavilion dv2700 laptop I bought back in 2008. Recently, the LCD back light blew out but I can still see the display. I want to replace the whole screen panel, but I can only afford just the inverter. Do you guys know how to change the inverter for a HP Pavilion dv2700 or know any Youtube videos showing how to? Thanks in advance!

You can go to HP.com and find the service manual for your laptop. The actual model number is on the bottom of the laptop.

I have to ask why you think it is the inverter rather than the LCD panels backlight? Either one can cause a dim screen.

For this model HP Pavilion dv2700 CTO Entertainment Notebook PC which is only one of the many dv2700 family of laptops.
This is the service manual.

I lowered my options down the the screen panel or inverter problem on my laptop. Since the inverter is cheaper, I'll start off with that. Thank you for the guide too!

Good Luck, I'll be interested to hear how you make out.

One thing to watch for. The connectors used in laptops are delicate. Always unplug cables by grasping the the plug. Never pull on the wires. I use a Large tweezers to grab the plug when I work on laptops.

Update:

I was able to replace the inverter. I started up my laptop and then The screen lit up again to show the HP logo, but then the screen blacked out again with the display visible and LCD light not working again. I connected it to an external monitor and the LCD screen light of my laptop appeared again, but then blacked out with the display visible.


Is there any way to fix this when I have the new inverter in?

It wasn't doing that before?
If so you may have both a bad screen and a bad inverter. This presumes you got the right inverter.

Wish I could give better news.

The next step is try a new screen with the new inverter. They could have both been defective. Not common but if the screen didn't act this way before with teh old inverter then bad screen and inverter or the new inverter is bad or the wrong one.
