Do Lcd Rear Projection TV's And Dlp Lamps Really Go Out After 3 Years Of Use Or Is That Just An Estimated Time

Question

i have had a mitsubishi projection tv for 10 years and never had to replace an bulbs.

Answer 1

its more like 6-8 years i think. my sony lcd rear projection hdtv came with a free replacement bulb which is worth about $150 itself. but ur open box model probably won't come with that.

Answer 2

Mitsubishi, as far as I'm concerned make the best DLP T.V. 10 years is a long time for the bulbs to last. Try not to move your T.V as that alone can cause the bulbs to go out. $150 for the bulbs if you know how to change them...

Answer 3

They did not have single-bulb projection tv's 10 years ago.

You have a rear-projector CRT unit. This unit has 3 large picture tubes which can last 10-15 years and is thicker and deeper.

The early LCD and all DLP televisions use a single projector bulb which has a lifespan of about 3,000 hours (roughly 3 years of average TV watching).

The advantages is that this design is cheap and simple using mature technology.  

The bulbs are pricey because you do not just replace the bulb - there is a small metal rack that holds the bulb in a precise alignment for the optics.

I just had to replace mine and the timer inside the TV that counts hours of use said I was around 3,600 hours.
