Thanks very much for advice, I fixed my webcam on my DV6 by just peeling the bevel off at the top as you described (with laptop running) and pressing the webcam cable clip (it was a multicoloured clip entering from bottom of webcam to the right hand side)

To see whether it had connected I opened up the Device Manager and looked under “imaging Devices”, before I pressed the cable I had no imaging device, afterwards it came up automatically.

All good now and easier and cheaper than taking it to a technician but would have been good if HP had a better design in the first place as it seems it is a common problem and something they could have fixed.

Travis,

Questions:
1) Is it possible for my laptop to not have an inverter board?
2) Is it possible for the inverter board to be somewhere else like closer to the motherboard?
3) There is a square area covered with some sticky foil behind the screen, Is it possible for the inverter board to be square and hidden under this sticky foil?
4) Is it possible for the inverter board to be permanently attached to the screen? (e.g., when I buy a new screen a new inverter board comes with it, because the inverter board is part of the screen.)

HP Pavilion dv7 notebook comes with two different types of screens:
1. CCFL backlit LCD screen. This screen requires the inverter board.
2. LED backlit LCD creen. This screen doesn’t require the inverter board.

You have a LED backlit LCD screen installed, so there is no inverter. The video cable runs directly from the motherboard to the LCD screen.

I just updated the post and mentioned two different types of screens at the end.

I have a HP Pavilion Qdvt7-3300 and this worked great!!! Thank you Thank you Thank you!!! so much! Nonetheless, I did not find an inverter board when taking out the screen. (Not that this matters for my purposes, but I am still curious.)

My screen model is: LP173WD1(TL)(C2)

All I can say is Thank You, Thank You, Thank You!!! I consider myself to be pretty capable of doing most things, but I was feeling a little intimidated after watching a couple of differ youtube video. After finding your instructions, I was able to tackle replacing my screen within 1 hour – mostly because I didn’t have a small enough screwdriver and had to use the end of a sharp knife! My laptop is a dv7-3188 so it was a little differ than the above but easily figured out. I’ve gotten it done and it looks GREAT! Our local computer store was going to charge me $130 for the screen and $66 to put it in. Now I only have a total of $82 into it…so, so excited! I think my husband should let me spend the difference

Hey again!

Yes,i’ve tried that before i decide it to taking apart the entire laptop and display aswell!Normally,this is the first step when you decide to isolate the failure…So,i’ve take it out the lamp,and has the both edges black,so i presume it’s old &burned.
Now,i’m waiting for the new lamp,already ordered from the link you’ve posted.
Thanks a lot for your fastest reply,and i’ll keep you informed.
All the best!

@ Toni,
Maybe it’s a stupid question but have you checked LCD screen brightness settings in Windows OS?
Normally you should be able to increase/decrease LCD brightness using a keyboard shortcut.

Hello,
I have an Hp dv7 1105eg with poor screen light and i’ve just changed the inverter with a new one,but the screen it’s still darker…i’ve already checked with an external display(LCD,TV)and it’s working fine!
Please,can anyone tell me what can be!?
