The lamp on your model comes out a small door on the left side of the tv, if you take the speaker cover off on the left side below the screen (it pops right off, just pull) you will see the lamp door then if you look there is a screw you must take out, once this is out you need to remove 2 screws inside and then pull on the handle it will slide right out. I have included a link to your instruction manual, if you click on the link and go to page 94 it begins talking about replacing the lamp, there are also instructions with pictures there.
If you have not purchased a lamp yet, there are many places online you can get them from, my favorite is http://www.dlplampsource.com/
Here is the link for the instruction manual:
