Hi @albereinst10408
Here's the [https://dl.dell.com/content/manual25870910-dell-g15-5510-service-manual.pdf?language=en-us|service manual] for the laptop.
Go to p.35 to view the procedure to remove/replace the display assembly.
Looking online it seems that you can get just the LCD panel or the complete display assembly.
Search for ''Dell 87TPD'' to find suppliers of the complete display assembly.
I can't find the part number of the panel but if you want t6o try just changing the panel, perhaps check of the back of the LCD panel itself to find a part number or a manufacturer's make and model number and then search for that. LCD panels are made to order by specialist panel makers and not by the manufacturer of the device.
