I assume you mean the 52XV540U. It does, of course, have a backlight bulb. But yes, it will likely outlast the bulb in projectors many times over. But it will eventually fail, or dim enough to be of limited use. Not really a big concern, so I agree "there is no bulb issue" but wanted to clarify that this LCD, and almost all LCDs, do have "bulbs" or "tubes" to backlight them. LCDs shutter light, they do not generate light like PDPs or OLEDs do.
