DEAD PIXELS! = SHARP XVC20E - Advice?

I purchased my SHARP XVC20 about 3 weeks ago, I'm really happy with it
apart from about 1 week ago it developed a single "dead pixel" - this
appears as a permanently white dot - this definately wasn't there when I
first got it.

Is this normal? - Do I have any rights? i.e. Am i entitled to a
replacement, or is this unavoidable with LCD projectors?


The projector manual contains a note, saying that pixel may die but it
"won't affect enjoyment" or something like that (don't have it to hand).

Any advice will be much appreciated.

Hi !

Welcome to the world of LCD-Projektors :-))

Well the problem is that there is a european-wide confirmation of all
LCD-Producers that dead pixels will only be covered by the guarantee when
there are more than 15 dead pixels. But i would go to your dealer and do a
reclamation.

Normal "dead pixels" don愒 happen often to lcd projectors. But be happy that
you扉e got a white dot. A friend of mine also got dead pixels, (2) but he愀
got red dots. That愀 really ugly.

Sorry that i couldn愒 give you better news.

Greetings from austria/vienna

You are entitled to have every aspect of the unit working, I assume you have at
least a one year warranty (typical for the UK), even without an additional
warranty you are still entitled to a repair. Since you have not had it for
very long I would say you also have the right to a refund or replacement. Time
is of the essence in the eyes of the law of consumer rights so decide what you
wish to do right away.

LCDs are not guarenteed to fail, usually if pixels are dead they were dead when
they leave the factory. Failure can happen during use (but is fairly rare, as
is any major failure in any projector).

Is this some sort of LEGAL agreement?

I must have been unlucky as there were DEFINATELY no dead pixels when I got
it.

I'll get on to the supplier - I'm expecting them to argue about this, so I
thought I'd get my facts straight first.

You can try hassling your dealer or Sharp over the dead pixel... but I don't
think you will get anywhere as they normally state somewhere that there is
tolerance of 7 or so dead pixels.

Are you sure it is a pixel drop-out... it may have sucked in some dust and
left it to settle on one of the LCD panels... dust will normally be smaller
than a whole pixel... there are companies that will clean out your projector
for you.

Dust and dead pixels are then anathaema of LCD projection (and fan noise).
Just one of those thing.

Sorry,

Leon

Does their "tolerance" statement have any LEGAL bearing. Noone said anything
to me about it when I bought the thing?

Surely dust would cause a black dot rather than a white dot??

If it happens during use, it tends to be in the first week or so. Once
you're past that, the risk seems to diminish.

A few manufacturers (Sony is one of them but I think a couple of the other data
projector maker manufacturers do too) use a dual transistor technology
to reduce the chance of failure. In theory this is a solution, as on
a million pixel panel the chances of the same pixel failing twice
is virtually nil. In practice it doesn't seem fool proof.

Well the problem is that a "dead" pixel isn´t a reall "damage" on the
projektor. The legal situation is the following: The projector works fine,
everything you want to do with the projektor is possible, so there isn´t a
damage which would be covered of the guarantee.

Hmmm Not sure i agree. When I want to see a black screen. I see a black
screen with a white dot! - The projector does not work fine in my opinion.

Yes, i also think so. But the industry doesn´t think so and the legal
situation is as i described. Maybe you have luck and get it repaired.

If your dealer blocks, call sharp directly - this is in most cases more
effective !

Can't post a directly helpful comment here apart from 'good luck'.
For this very 'drop out' reason, I wouldn't advise anyone to touch an LCD projector. CRT are more expensive and harder
to set up, but this pixel thing is rediculous.

John,

I have had the same problem with the Sharp XV380H. I went through four
machines, all of which dropped a minimum of 6 or so pixels. In the ned I got
a refund and went for a large rear projection set. If I were you I'd take it
back to the store and demand a replacement right away. Official blurb from
Sharp say you need a minimum of 6 dead ones for a swap, but I don't think
you'll have a problem.

Hope this helps

You clearly didn't do enough research to know what you were buying.

Pixel failure is common. The Owner's Manual will typically state an
expected and accepted failure rate of pixels (8 is common) and there is
no legal redress.

The projector is operating within the manufacturer's stated tolerances.

Pixel failure is the risk you take with LCD projectors.

If you didn't know this during testing and the pre-purchase stage, what
other criterion did you use?

I am amazed you purchased an LCD projector in ignorance of well
documented pixel failure, this is the first negative on the list of
positive/negative qualities of LCD units.

Buyer beware - chances are you won't hear it from an in-store sales rep
and if you do make a purchase decision based on their evaluation you're a
mug.

Sorry folks - but there is now a plethora of information/experience about
used projectors..use it before you buy one.

I bought a Sharp XVZ1E 2 weeks ago. Its lovely. Towards the end of last week
though I noticed a light grey speck in 1 location on the screen. My heart
sank. Then I remembered someone told me about dust problems and that it may
need to be cleaned somehow.
My first reaction was to wipe the lens. Then when that failed to clear the
problem I ....No WAIT! That cleared my problem. No more specs!

Anyway, can anyone tell me if there is (eventually?) a problem of dust
inside my projector is it possible to use a little vacuum (or 'blower')
thingy myself rather than send it away?

I do hope you don't have a dead pixel John. I made sure mine was dead pixel
free before I bought it and thought (and still hope) the chances of them
dieing thereafter are pretty slim.
Let me (us) know if it turns out to be dust. I think dead pixels are usually
red.

-Kevin.

I also am lucky to have a XVZ1E but I have a dead pixel,which to be
perfectly honest you can only see it with your nose on the fabric of the 4'
x4' screen i'm using at the moment.

I also seem to have a slight smearing on a few small patchs which is much
larger than a pixel, which I think may be fluff in the machine or grease on
the lense.

Anyone else had anything like this ???

(I expect it's what happens when you spend your money on a DD amp rather
than a dyson!!)

Going slightly more off topic but usefull to prospective XVZ1E purchasers:-

The XVZ1E is really nice but if anyone is planning to buy one really haggle
i.e mine was 2300 UK Pounds as opposed to the 3500 rrp price that is used
for intreast free credit deals in HCC.

Dead pixels!

Ha!

What about live flies?

Whilst watching Sky news on Sunday I was
moved to comment on the superb quality of the
transmission. On further contemplation I marvelled
at the ability of a fly to enter a graphics image.

And then the penny dropped. I've got a fly
wandering around on the inside of my Sony 41"
RPTV. Never thought I'd enjoy studying the
underside of an insect.

How many live flies before I can demand a replacement?

.yeah..sorry... guess that was a bit harsh...but what research DID you
do before you bought your projector?

The only other issue to consider is even if you did get a replacement
unit would you want to risk pixel failure again?..chances are sooner or
later that they will fail..take a look at any lap-top computer screen -
same thing..

.the Sharp projector I saw had several 'blue' pixels that had
failed..how Sharp ever believed 8 failed pixels was within tolerances is
hard to fathom..

If you have ever seen an LCD picture with 8 failed pixels you would know
it is totally unwatchable.

No worries. Well i read every review I could find and I posted on this
newsgroup (no response at the time). No body warned me about dead pixels.

I'm still not convinced that Sharp putting a note in the manual means I have
no legal redress, A product has to be fit for the purpose. It's as simple
as that.

Could I sell a bucket with a hole in the bottom, and put a sticker inside
saying "there is a hole in this bucket, it will not affect your enjoyment" ?

Hey, if someone came along and gave me a high end LCD projector
with 8 failed pixels on it, believe me, I'd be watching it!

I'd be straight back down the dealers, asking politely for them
to change it, and test the new one in shop for 4 weeks, and after
that I would check it for dead pixels and then accept it if none
were found.

If they didn't want to play ball it'd be contact the manufacturer,
contact Visa (it was paid for by Visa wasn't it?), contact trading
standards, and finally handcuff myself to something just outside
the shop and moan as load as possible :->

Jees ! You can get a Seleco 400 installed for less than that !!!!

Not for long you wouldn't...

And that is the point. CRT projectors are competitive now.

I looked at LCD projectors back in 1991. I couldn't stand the
'fly-screen' pixelation..I gave up on the technology and bought a 2nd
hand Panasonic (CRT) PT-102 projector in 1992.

I learned a lot about convergance and the basics of setting up a large
screen projection system and never regretted the choice.

My projector has been thrashed - probably 2-3 hours per day, every day
since July 1992.

The other factors that come into LCD units is the fan noise - it's way
too high in a domestic HT enviroment...you wouldn't accept it in a
theatre (certainly not a THX theatre..)

.and the picture quality itself has (apart from the pixelation)
a 'staggered' quality to it...if you look at LCD pictures large or small,
movement across the screen seems to be a connection of isolated actions,
rather than just a normal progression...(it's very hard to describe)..
try small screen hand-held TV's or lap-tops the picture has the same
quality..

.it is as if each pixel is suddenly 'switching on' to receive the
information..anyways, if you enjoy it, enjoy it..some of the new LCD
units are spectacular, but at $20,000 I'd still prefer a Seleco.

LCD bulb life is also a factor - they do blow and they do wear out.

Always remember when you use a projector that it too, is an amplifier..it
will amplify poor quality pictures and expose them cruellly...get a good
source and it too will be amplfied and exagerrated for the better..

Lastly, a projector is only half the equation (like turntable and
stylus/arm), the quality of screen is absolutely VITAL..I'm amazed at the
number of people who buy and LCD and show it on their basement wall...

Have fun which ever route you choose..

Later

Max C
