I cleaned my 60" big screen tv (Samsung DLP) screen yesterday with tissue
and glass cleaner, now a black triangle about 5 inches high has appeared
in the lower left corner, very annoying, looks like perhaps some of the
cleaner somehow leaked behind the screen, damaged something or whatever. I
am depressed about this of course. Is there any way I can fix this myself,
or even pay a TV repair person to fix it? How serious of damage, what sort
of damage, might I have done? Any feedback or help greatly appreciated.

Yeah I am not feeling good about what happened, might call the "TV Doctor"
repairman today, see what he says, but curious if anybody else has heard
of what happened, seemed if might be common if caused just by cleaning the
screen. Not sure what I will do if it can not be repaired, I guess try
and sell it used, buy a new one.

I dont think you're supposed to use glass cleaner on them at all...they make
special screen cleaners for them...I hope you didnt use a cleaner with
ammonia in it...

Yes, it was "Glass Cleaner with Ammonia". Am I screwed? Can I have a TV
repair guy fix it for a few hundred? Actually that would be worth it-- I
am dreading the thought of buying a new TV at a cost of $1500-$2500.

glass cleaner typically has ammonia which can damage coatings, but not
like what happened to you. Is the set under warranty? Sounds like a defect.

I think I *might* have gotten the extended warranty. But I would think
any warranty would not cover my stupidity as using ammonia based cleaner
when the instructions likely said to just use water or a bit of soap and
water. I screwed up. I hope an ext warranty might cover it, but if I can
even get away with paying just a few hundred I will be relieved.

then don't tell them.

The only thing ammonia based cleaner will do is possibly discolor the
surface after many years of exposure.

Well, a DLP screen is just that, a screen. Not like a plasma or LCD where
it's most of the cost of the unit. That doesn't mean the mfg won't still
try to charge most of the cost of the unit for a replacement though.

#1 Do not use GLASS cleaner on PLASTIC.
#2 Never spray any cleaner directly on a Tv screen
#3 Do NOT tell the repair person what happened. Maybe they will just repair it
under warranty.

I agree with #3. #1 is overstated. Glass cleaner will eventually discolor
the screen, but one application won't have any noticeable effect. No
ammount of applications will crack a screen.

You DO NOT want to use any cleaner with ammonia on plastic, period!

You have probably damaged some of the non-reflective coating on one
of the surfaces and are looking at a replacement cost of a few hundred
dollars. Just out of curiosity, what does the owner's manual say
about screen cleaning?

I would guess soap and water, or just water, sigh. I know I screwed up.

On my DLP rear projector (Sagem) it's an easy job to remove the screen.
(mine was delivered with the screen pushed in out of the rubber surround
in one place and I fixed it myself rather than get a repair man out) I
can't see why it should be difficult on any make. The screen is some form
of flexible plastic so I'd not use glass cleaner, but just mild detergent
and water.

why not call the people that made your tv & ask them what todo?

I've read all these posts, and there's no correct answer to this problem.
Whats happened is that some of the cleaning solution has run down to the
bottom of the screen, into the U shaped ledge that holds the screen, and the
fresnel lens behind it. It has then "wicked" up between the two sheets of
plastic, and is causing the dark spot. You can probably get the spot to
change shape slightly if you press gently on the screen. And its a very,
very small amount of water.
So, to fix it, get a hair dryer. Put it on LOW (!!!) and slowly move it
back and forth over the wet spot. Dont want to get it hot, just warm to
make the liquid evaporate. The spot should
disappear, unless the cleaning fluid was very, very contaminated with dirt,
doubtful.
No new screen needed.
BTW, some time back, I had a HD big screen Toshiba come in that had been
marked on with crayons, magic markers, and who-knows-what -else by children.
I used a can of WD-40
and a fine toothbrush to clean the screen, worked like a charm. Had a great
picture, sold it for over $600.
Try drying your screen before you do something drastic.
And, I have to admit, I've done the same thing, and created exactly the same
problem when I clean my 60" Pioneer. The problem will go away with
time,(evaporation) but the hair dryer will cure the problem quicker. Oh,
and I use warm soapy water on the Pioneer. In very sparing amounts....

oh man did i dodge a bullet on this one! The screen is back to almost
normal, that black rectangle is 95% gone, I had the heat in my home turned
up to 70 the past couple of days because of cold weather here in northern
MN, and brought up the hair dryer to do what you said and the spot was
almost gone! Evaporation from the heat in the house and low humidity. I
still blew the hair dryer on it for awhile, will do so more later. I can
live with it the way it is, hopefully more of it will still go away.

I just do not understand what causes the black coloration if it is just a
liquid, that is the bluish glass cleaner liquid that got up there. Just
curious, if anybody knows. Polarization of the liquid or something?

Thanks all for the help, even though this time I did not have to buy a new
screen. I was just SICK over the thought of $800+, I am sure going to be
VERY careful now about cleaning the TV, taking better care of it, reading
manuals (ok, yeah right, like we all say we will wash and wax a new car
the first days after driving off the Dealer's lot, LOL).

Just whatever you do in the future, never spray cleaner directly on the tv
screen, apply it to a cloth then clean with that. Also never clean a TV with it
turned on. Static just attracts dust like a magnet.

That's exactly what could have happened. If any cleaner got between
the screen and the outer protective screen, it will cause this type of
problem. There shouldn't be any damage to the screen, but it may take
a while for it to dry completely. It might have to be disassembled
for proper cleaning, but there's no serious damage. Glass cleaner
shouldn't hurt the screen if used occasionally.

Spot is almost gone from drying, and like you say I might at worst have to
pay $100 for a repairman to come and clean the inside of the screen if
some of that "black" residue sticks and does not evaporate. Man that is
much better than a new TV, or $800 to replace a screen!
