Fresnel lenses	Can't Post

I don't really know anything about TVs but am looking for a Fresnel lens for a science project.
I can get either a Toshiba 42pw23p or a Toshiba 40PW8DB second hand, and I was wondering which will contain a Fresnel lens. If both do, which is going to be bigger/better?
Thanks in advance for any hlep you can give me!

projection tv's have a fresnel and a lenticular lens. In your case the 42inch will be bigger
