How to Replace the Lamp on a CRT Rear Projection TV
Rear projection TVs come equipped with a lamp or bulb to ensure your picture is bright and clear. As with any bulb, it eventually burns out, which results in a dim television screen. Most rear projection TVs also come with a lamp hour counter, which warns you when the bulb is close to the end of its expected lifespan. The process for replacing the lamp is similar for most televisions. However, check your user guide for specifics such as what replacement lamp to buy and where the lamp is located in your TV.
