Will Bestbuy's performance service plan replace the fried lamp on my panasonic pt-50lc13 lcd projector tv?

bought this tv in july of last year and today when i turned on the tv
the power led blinked green then red. seems to me the lamp needs to be
replaced. i did buy the bestbuy's 4 year extended warranty and was
wondering if it will cover the lamp. i'm waiting for the service guy
to call me tomorrow and see what he says....

I purchased the extended warranty on a projection TV from Best Buy as they
told me (sic) that adjustments and such are covered. Of course, they
weren't. So, I asked for a refund, and they prorated it.

But, in your case, unless BB can *prove* abuse, it's covered.

makes perfect sense

Best Buy sells the policies for "peace of mind"

You had plenty of peace of mind until you found out the Best Buy policy was
worthless.

Thus they prorated it.

the bestbuy service guy called me and told me he'll mail the lamp with
instruction on how to install it. i didn't want to wait till my off
days for him to come so i figure i can just do it myself. he said the
the warranty will cover lamp burnt out until my warranty expires.
good thing i bought the warranty..... what other type of hdtv(dlp
projector, plasma, lcd....) don't have this problem. this will be the
last time i buy lcd projector tv....

Did he ask you if the power LED flashes for 2 minutes in addition to the
lamp LED coming on? If it does you may have more than a bad lamp and the
ballast may need repair. Some of this model have this problem.

Lamps go out. Direct view LCD uses backlighting but not high intensity arc
lamps like RP. PDP, and CRT based products do not have lamps. RP LCD, DLP,
LCOS, SXRD, DILA all use similar lamps.

Right. Direct-view LCD panels usually use cold-cathode
fluorescent lamps for backlighting. They go out as well, but
the expected lifetime is pretty long compared to projector
lamps. CCFL MTBF is usually on the order of 50000 hours.
That's 34 years at 4 hours per day.

PDP, and CRT based products do not have lamps.

CRTs have filaments in them that heat up to orange/red hot.
They aren't "lamps" but they will go out the same way that
incandescent lamp filaments do. CRT MTBF is typically somewhere
around 30000 hours, but I think cathode and phosphor usually
wear out before filaments burn out.

RP LCD, DLP, LCOS, SXRD, DILA all use similar lamps.

Projector lamp lifetimes usually seem to be quoted as 1000-5000
hours depending on who you ask and how bright you run them. At
the low end, that's only 8 months at 4 hours per day.

That's why them make them user-replaceable.

Most of the current lamps are rated for 2000-8000 hours, but they vary
greatly.

CRT filaments rarely wear out. Sometimes we see them open but this is
unusual. Phosphors and cathodes seem to age out at similar rates in most
sets, but this varies a great deal as well. Cathodes (and grids) age by
deteriorating and by building up a layer of oxide. Most manufacturers
resist giving a life spec. When they do they will usually specify time to
50% brightness on the phosphors, not MTBF. Again, they vary a great deal.
30,000 hours is probably optimistic for many sets, likely underestimating
the life of higher qualtity sets and sets run at more reasonable contrast
levels than factory presets.

no he did not ask me that. i guess we'll find out after i replace the
lamp...when i press the power button, the power led flashes green for
about two minutes, then it flashes red along with the lamp led
flashing simultaneously and indefinately....
