Sony rear projection TV lamp problems !!

[Kenno24]

I own a Sony KF-WE42 rear prolection TV I am sad to say. The set is 16
months old, has run for 2600 hrs. and is now on an extended warranty.
The lamp has failed,Sony don't want to know and the extended warranty
does not cover a new bulb. Sony will not even offer a pro-rata on the
price of a new bulb. They say that it should last between 6000 and 8000
hrs. YEAH, RIGHT !!!!!!!!!!!

I discourage our clients from buying any type of rear screen technology,
especially the ones that use lamps. The lamps are expensive, and do not
always last. Sometimes they will go more than the full rated hours, and at
times they will not even get half the rated hours. A lamp is really an
unpredictable device. In theory, if the temperature of the lamp is well
controlled, and it is not power cycled very often it should last longer.

I personaly would get the set working, and then put it up for sale. Then go
and get a good flat panel type TV set that does not use projection
technology. The LCD sets should give you at least 50,000 to 60,000 hours
before there are any problems. With LCD sets, there will be no lamp changes.
With the rear screen sets, by the time the life span of the set is over, you
would have spent more than the difference than if you bought a high end flat
panel LCD set in the first place.

Power cycling is very hard on discharge lamps in general. Metal halide
lamps for general illumination are often rated 15K hours @ 10 hours per
start. Sports field lamps are normally somewhat higher power, but are
normally rated at 3K hours @ 3 hours per start. The warmup cycle puts
very high stress on the electrodes.

LCD sets _will_ require backlight lamp changes, only less frequently.

Do you know anyone who has changed a backlight in a consumer LCD flat panel
display? If you do it is a rarity. They are not only very reliable, and
likely to outlive many of the other components in the sets, but are usually
not available as replacement parts.
