for now.

This tv has a smudged / blurry area on the screen. It looks almost like it
is dirty from a oily hand but it doesn't wipe off. It is not a rectangular
area.

I am not familar with the common failure modes of Plasma displays. What is
your best guess would cause this.

Thanks in advance,

Mike


Is there anything between the front of the plasma panel and the user?
Dust/Dirt gets sucked in by fans and deposits itself
on any available internal surface.

Someone used solvent to clean the screen?


Interesting idea.. That's a case where the screen could be fixed... I
will have a close look at it in a couple of days.
The price is right on this thing, but I don't want to sink money into it
if the screen is about to crap out.. Since that's the one piece that cant
be repaired.


Lets not get ahead of ourselves - do we know for sure it's really a plasma
and not an LCD? My customers often confuse the two.

If not damage to anti-glare coating which has been suggested, it does
sound more like an LCD type problem to me.

To be honest Mark, I'm not sure that as described, it actually sounds like
any kind of display technology fault that I have seen. I would be struggling
to think of any kind of LCD problem that would result in an irregular
smudgy-looking mark, unless it was an actual physical mark on the surface of
the panel ...

I will let you know if I finally get a chance to see this thing again.. I
saw it very briefly and it wasn't a major flaw. Had I not been told about
it, I'm not sure that I would have noticed right off. Seeing it I thought
it was a very strange fault if electronic, but I haven't seen a plasma fail
except in getting darker or burn-in. Anyway. . Hopefully I will see it
tomorrow and solve this mystery.

Ok I got another look at this TV. It is a Hitachi W32-P5000
Upon close inspection it appears that there is something on the inside of
the front glass.
You can tell by looking closely moving side to side and watching pixels go
from blury to clear

My next question is that is the front glass typically seperate from the
plasma display or is it part of the
display like an LCD tv. If it is indeed seperate it would be an easy fix.
My best guess is
that its seperate but as I said I dont know anything about these and dont
want to drop $160
on something that I cant fix.

By the way, thanks everyone for all of the insight. This group has always
helped me in my
electronic ventures.

Forgive me if this is a double post. It seems that it didn't work.

I had a closer look at the TV today. It is a Hitachi W32-P5000.
Upon closer inspection it appears that the "fog" is on the inside of the
front glass. I can tell by looking closely and moving side to side. The
pixels were obviously clear and the front glass is fogged.

The next question is that if the front glass is attached to the Plasma
display.
If its not this should be an easy fix.
 
I'd get in touch with Hitachi today, or tomorrow at the latest (even though
"in touch with tomorrow" was Toshiba's slogan). I'm not so sure this is a
case of the protective front surface pulling away from the panel.

You'd have to get ahold of someone who has either tried to separate the
front glass or who has successfully separated it. This is going to be a
real challenge because it is not something that is normally done. I don't
think I'd toss $160 at the owner either for the chance to find out on my
own.

I would pass on this unless you can live with it as it is. I am
definitely no expert but it sounds like and internally caused flaw or
manufacture flaw that was not originally seen by the owner.

My best guess by looking at it is something that is on the inside of the
panel, but certainly not the actual pixels. It is definitely tolerable. If
anyone saw it they would think the TV just needed to be cleaned in that
spot.

My son for some untold reason scratched the glossy protective cover on my
51" Panasonic rear projector. It was done with a pencil and maybe an inch
long vertical. It took me a very long time to stop staring at that
particular spot that wasn't anywhere near the center of the screen. I
think too that it would be too much of a distraction for me to watch a
set with a big smudge anywhere on the screen.
