toshiba dlp tv lamp problems

From all I can figure out by googling toshiba dlp lamp
problems I made a mistake in purchasing a new 62 HM 195 it is 10
months old and average use of 5 hours a day the lamp blew up the day
after it went to half of its normal brightness on the 20 of aug 2006.I
called toshabbi imediately and am still waiting for my warranty lamp.
BUYER BEWARE
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Re: toshiba dlp tv lamp problems

Moi has a 52 inch Toshiba DLP. The unit probably averages less than five
hours per day. The bulb lasted about twenty months although one of the
selling points was that it would last three years with longer viewing hours
per day.
Toshiba and the salespeople lied, imagine that!
Fortunately the extended warranty has essentially paid for itself with the
first bulb replacement and at this rate I will make a "profit" if this
replacement bulb lasts the same or less as the original.
However one of the advantages of a DLP such as the Toshiba is that barring
catastrophe, like failure of the DLP or light wheel, the unit should give an
as new picture for many years as long as you change the bulb. It is unlikely
current plasma/lcd (non-projector) can make than claim.

Unfortunately this is a common problem among all brands of micro-display TVs
with old-style lamps. That's why there's so much interest in the new LED
technology. There's talk of a class-action lawsuit against Panasonic for
just this reason. Sony and JVC have had lots of problems but seem to be
improving recently. But some owners get many thousands of hours on their
lamps, so it's a crapshoot.

Toshiba has reportedly extended the warranty on some of its lamps. Rather
than bitching and assuming that all Toshiba products are problematic the OP
should check to see if his product is covered or if Toshiba will help out.

The idea that all brands have problems with lamps is not correct. The idea
that all lamps have short lives is not correct. What is true is that lamps
have a large variability in life and are affected by the application, the
frequency of use and on/off cycles, the manufacturer, and other factors.
Sony's problems seemed to be transient. We never experienced it in any of
the product that we sold. Most of the manufacturers that have used Philips
lamps and ballasts have had much greater variability than those that use the
Osram products. In general, our clients have had typical life results that
exceed the TV maker's ratings. Some have had early failures but they have
been very rare in mour experience.

I certainly didn't say the second, but as to the first I haven't heard of
any brands of micro-displays that have totally escaped this problem. When I
first started following the discussions in late 2004, the Sony threads on
AVS were full of complaints about premature failures on the 610 models. I'm
not surprised however that your Sony customers have had no recent problems
with premature lamp failures. This is rarely mentioned on the A10 and A20
threads on AVS either, so they do seem to have gotten their act together. I
know that JVC has been encouraging their customer relations people to
promise improved lamp life. I hope this comes to pass. Premature lamp
failure is my only complaint about my D-ILA, otherwise I couldn't be
happier. I avoid delays by buying a spare lamp, which I recommend to all
micro-display owners.

By the way, do you have any thoughts on whether LED replacement units might
become available for existing sets? Or will we have to buy whole new HDTVs
to get LED lighting?

I doubt that you will see widely available LED replacement units for lamps.
There will be some folks who will experiment with it and there might be a
few custom applications, but not widely available commercial products. The
major vendors are not likely to attack things in such a product specific
manner. You would have to have spectral, mounting, and power supply designs
that are specific to each model.

Does JVC use philips or osram lamps? We don't see much JVC here and don't
sell it.

Our experience with lamp based products has been pretty good, if you
consider the manufacturer's rated life and you know what to expect up front.
We do not sell Samsung, Toshiba, nor JVC however. I do get service calls on
the first two, but not the JVC. I think a lot of the problems are
unrealistic expectations and a tendency to generalize the problems to the
technology that are often product and model specific. Same as with burn-in
doomsayers...

Did they? I've been running my Toshiba 62HMX84 for five hours a day for
almost exactly two years now with no problems.

Lenord
apparently you have not googled this toshiba problem, it has been going
on for over 2 years and I was extreamley unhappy with their warranty
support. The fact is I asked if there problem with the dlp lamps and
they said no which I believe is a lie after all I've read on the
internet. The simple fact is that I probably would not be upset if the
warranty dept had just said they were sorry and would over nite or
second day air me a new lamp.
Instead I am still without my 3000 dollar tv for six days now . So if
toshabbi doesn't pony up an extended lamp warranty I will do my best to
cost them as many sales as possible.

I looked on my backup lamp and it only says JVC (plus oriental script). It
also says "made in Mexico with Japanese components" if that gives a clue.

The problem with 'googling' for a problem is you only find problems.
Did they sell 10 or 10,000 with 'x' number of issues? You have a 100%
failure rate but NO idea what the actual numbers are.YOU got one of the
problem units so now ALL of them are bad and by God, they're gonna PAY.
I'm sorry your TV is on the blink but that's just the luck of the draw.
BTW, I thought is was a Toy Sh*t Box.

FWIW, as of this morning, our Samsung (Samsuck if yours is broken) DLP
has 5202 hours run time since Dec '03 with the original bulb. The spare
bulb (untested although Leonard rightly recommends using it) in the
closet was $115.

Are you two guys on the pay role you completely ignore the poor
customer support and the fact that this is a long term problem that no
body mentions whe purchasing the product.

Perhaps they understand that ALL products have failures, that anectdotal
evidence of problems does not necessarily indicate a problem inherent to the
technology, and that the information regarding life expectancy of lamps is
readily available to anyone who does a little "googling" or other homework
before buying. Perhaps they at least visit quality dealers and get real
information rather than relying on the children and used car salesmen at
Sears and Best Buy to inform them.

How many people get told that the convergence ICs in their CRT RPTV are far
more likely to fail than any other part and probably more of a problem than
the average lamp?

Be a smart consumer and do some homework BEFORE buying. Then when you have
a problem, address your energy to working with the consumer relations people
for the vendor to solve the problem rather than bitching about it on usenet.

Resettable lamp hours reading is in service mode under 'options'. If
you get the access code, be very cautious about changing things. I
strongly recommend taking pictures of the various screens full of
numbers BEFORE you do anything, including accidents. Its possible to
completely screw things up if you don't know your way around. Better
yet, the service manual was <$20 on a CD which lists all the default
values.
