Where is lamp location in polaroid 32 in hd tv

I'm not sure which TV you have. The Philips 50' plasma does not have a backlight. The Polaroid 32 can have a incandescent or a florescent backlight. The backlight is accessed by removing the back of the TV and replacing the lamps. There can be 1-4 of these light for florescent and 1-*** number of lights if incandescent, depends on the design, model, features, price point.
