samsung dlp and lamp life

Archived from groups: alt.tv.tech.hdtv (More info?)

Is the lamp issue with Samsung dlp an all or nothing phenomenon (it dies one
day) or do I need to worry about a gradual dimming of the screen that will
be perceptable after 3 to 4 years. Is gradual dimming an expected
phenomenon?

Quote from manual : "When do I replace it? (Bulb) It should be replaced when
the screen becomes darker, less color or when all three LEDs on front
(Timer, Lamp, & Temp.) are flashing."

You are welcome

So if you have a 4 year policy that covers a dim lamp (you get a
replacement) you might think about calling them in 3 years and 11 months and
say, "my lamp looks dim, could I get a replacement? Does my thinking make
sense?

You're thinking makes sense, but you better ask for specifics on what the
service plan covers and get it in writing. For example, at Tweeter they
told me that their service plan covers bulb replacement. However when I
asked about the nitty gritty details I found out that it ONLY covers the
case where you have the 3 blinking LEDs (i.e. the bulb burned out). They
said it did not cover the dim screen scenario that you mentioned.

Most manufacturers only guarantee the lamp/bulb for 90 days.
