I like to buy a DLP TV, but I wonder how often that I have to change the bulb and what is the cost?

Different models of DLP projectors use different light bulbs. Your TV's user manual should give you an estimate of bulb life (usually 2000-5000hrs). However, that is an estimate and not a guarantee. Some bulbs may fail sooner. More likely, you will find that the bulb dims with time, and the real end of life comes when you think that the picture has lost too much brightness. My DLP projector claims a bulb life of 2000 hrs (it is an old model--newer units have longer life). Howver, by the time it reached 1200hrs the brightness had dimmed considerably, and I replaced the bulb.
Note: all projectors (DLP or LCD) use similar bulbs, and all have limited life and are replaceable.

A DLP-based HDTV set should last indefinitely because the digital micromirror device behind it is very reliable. There is no maintenance or alignment required for DLP based sets as they age. The only consumer replaceable component is the DLP light source (lamp) which will last for 8,000 hours and costs around $250 to replace. The micro-mirrors used in DLP are not subject to degradation due to heat, humidity, vibration or "burn-in".
