Hi @mrmajorthorburn
Here's the [https://dl.dell.com/manuals/all-products/esuprt_laptop/esuprt_alienware_laptops/alienware-m18x_service%20manual_en-us.pdf|service manual] for the laptop. Go to p.20 (of 64) to view the procedure to remove the display assembly from the laptop base.
Here's a [https://www.youtube.com/watch?v=e4aQhm_HotY|video] that shows how to remove the cover from the display assembly so that access to the LCD panel is possible.
Hopefully this is of some help.
