With major parts, it’s usually more practical to buy a junk laptop with the parts you need and then keep the rest for parts, especially for LCD assembly issues. With a lot of these, there’s often hinge and back cover damage. Most of the time I add up the cost of parts for major work like this I can buy the whole laptop with a lot of missing parts because it’s got a major fault for very similar prices as I would for just the bare parts - if I’m paying more, I have a use for the rest of it.
See if you can find a similar laptop to yours since the specs do not need to match in terms of the motherboard if it’s dead, and negotiate it down to a price you’re okay with. Once you find the donor, take the parts off you need and transplant your good LCD, webcam and LVDS cable.
CAUTION WHEN BUYING A DONOR: In some cases, the donor has much better options that if you can verify it’s perfectly functional or needs a minor repair, take what you need and part ways with the original device. I have a few of those where I’m parting with the previous device if it has a serious issue and moving my SSD and RAM over. I would not hesitate to part ways with my LVDS HD 4600 (IGP) E6440 in favor of the HD 4600+8690M (dual GPU) I came to own due to cross part compatibility negligence.
