As a bit of perspective on choices.
I work in the field of IT, as a network admin. I have seen technicians replace dozens of screens, and I have always preferred them to do it. While we have warranty etc, taking it to a third party - one advantage you have if the replacement doesn't work, particularly if they provide the part, is that they agreed to fix it for x cost. If you do it yourself, and the screen is faulty, you then have to source another one at 90 again, which means it would be 180.
I pull hard drives (particularly for data recovery) and ram from laptops all the time, and I have replaced a keyboard or two, a couple of DVD Drives. These are all parts designed to be user serviceable. An LCD is not. Without the proper tools, you can easily break tiny plastic clips, cables etc. While I might have an attempt as a long shot if a device was out of warranty (never while in warranty), if one part has failed, particularly with a burn out right after a power surge from a storm etc I would be highly suspect of the other parts.
We even have qualified technicians say that some screens are a nightmare to replace.
Laptops are not really meant to be user serviceable other than the parts marked as such. And even then - user serviceable, is a label that has certain expectations. Many of the devices I support, I would not trust the end user with a screwdriver.
