Price of a Sharp 19' Bulb
 

I'm just wondering bout this but how much would it cost for a new bulb for my Sharp LCD 19' TV? How long do the bulbs last in those things anyways?

LCD tv's do not require bulbs nor are they 19 feet in size.

Perhaps try a google search with your model number or go to Sharp's website if you have a DLP tv.

Okay! Sorry I didn't really realize there were no bulbs in LCD TV's thatnks for the information though.

Well, there's a backlight of one sort or another in a flat panel LCD. But when it goes out a new TV probably costs less.

The backlight probably costs < $10 but it can be very difficult to replace (soldering and lots of disassembly required). It's not easy.
