Finally! A decent HDTV direction!

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

While I love the LCD and DLP RPs I just dont trust the lamp
manufacturers. Way too much money for replacement lights. If someone
told you a replacement $300 SD TV was necessary every year you would
probably freak out.

Now the direction for LCD RP sets is FINAALY- FINALLY heading toward
super bright LED light sources. First sets are comparable in price to
plasma, but I would think this would be the choice over plasma to end
all the choices. Except for compactness, I guess. Anyone have any more
info on this?

Not all DLP (nor LCD) lamps are rated for 7000 hours. I have seen
manufacturers stating life for lamps in DLP and LCD projectors units from
1000 hours up to 8000 hours.

Generalizations like you made can be very misleading. One should check the
rating for a particular product then check with dealers (servicers) to see
if that product typically gets the life expected.

It is not impossible at all to be more clear and less likely to confuse.
All you have to do is say Samsung estimates 7000 hours, not DLP lamps last
7000 hours. It depends on whether you are trying to inform or trying to
support a point.

BTW, Samsung may have sold more DLPs than anyone else, but that hardly makes
them the only player, nor the "leader", necessarily. In fact, of the DLP
RPTVs on the market, the Samsung products are near the bottom in
performance.

Manufacturer estimates are, of course, very variable themselves. The same
lamp used by different manufacturers may be estimated to have very different
life. Some manufacturers are more conservative than others. Some want a
sales edge up front as opposed to being more likely to meet their customers
expectations in the long run. The quality of the performance of lamps can
degrade somewhat with time, as well as the likelihood of the lamp failing by
shattering, which can be a real mess. Typically the higher end products
will have a more conservative life estimate. For instance, the lamp that
Yamaha rates at 1000 hours of life is estimated by the lamp manufacturer to
last 2500 hours. I have never seen one last less than 1000 hours. On the
other end of the range is Sony's LCD units with a life claimed at 8000
hours. We have seen many fail at much shorter times, even aside from the
bad batches of lamps that they got from Philips. Likewise, many Samsung
lamps don't even get close to 7000 hours. Lamp life is very variable. That
does not mean that we have to be vague when it is possible to be specific.

The field of HDTV is hardly "randomly mutating." There are very clear
patterns and lots of variability within those patterns. There is no need to
make the complex market more confusing by over-generalizing, especially when
you have the ability to be more specific.
