Can anyone offer any advice on the replacement of the protective screen in
front of the plasma panel.
(Have got a customers set with a cracked glass)

Is there a safety issue regarding special coatings etc to protect from RF
interference etc. Or could one just use -say tempered glass.
I can't measure any resistive coating. There are 3 plastic stick on covering
sheets none of which have a conductive coating, just a tint.

Do plasma panels emit any unwanted particles besides light from the
phosphors- and need special screening?

Lets see, massive amounts of infrared, small amounts of xrays, and
some uv light are all filtered in the front protective glass on plasma
tv sets. I am not sure it is available separate from the entire
plasma screen assembly on most models.

Buy another Plasma Television, The one that is damaged is beyond economical
cost to repair.

Wait a sec, he said it's just glass over the face, is the panel itself still
intact? If it still displays a picture then the panel is good, I thought the
glass on the front was part of the panel itself but if it's not then a piece
of normal glass should work. There's nothing particularly dangerous emitted
from a plasma panel, some UV, but that will be blocked by ordinary glass.

Hi JVC Dude,

As David say's Plasma panels emit huge amounts of IR radiation. I have been
told that it is so great that if you remove the IR filter (The bit of glass
your talking about) all remote controls in the room stop working!

In all the models I have worked on there is a piece of specially coated
glass in front of the PDP to stop IR radiation. Haven't you seen the video
on the internet that came out several years ago when plasma was a new
technology. The news reader touched the front of a PDP and jumps back in
surprise saying something like "**** that's hot"

What Brand/model are you working on?

Hi The model is a JVC AV42PD20 - the pdp works fine and it is just
the glass screen thats seperate from the pdp thats cracked.
JVC want £834 for a new 'screen filter' as they call it- so yes I presume
theres something special about it for it to cost so much. It just seems a
rather ridiculous price for a 3mm piece of glass with a coating, and 3
layers of plastic filters.
Do other manufacturers charge similar figures for their screen filters?-
perhaps since 42" is a common size, another manufacturers screen , if
available at sensible price, would do .

any one know who charges what for these screens (in UK)

Been repairing the Pioneer, Sony, Panasonic, Etc Plasma units. All the
Manufacturers indicate any kind of glass damage to the front panel-screen
assembly will require replacement of the complete panel assembly due to the
high probability of loss of seal between the cells and eventual failures.
Therefo in most cases addressed, when there has been any type of cracking
and/or damages to the front panel assemblies, inclusive of the overlaying
glass, the Manufactures furnish the cost of a replacement panel, then the
servicer is required to change all the electronics, mounting, and enclosure
assemblies to the unit before considering the item being operational. The
cost of the display section is usually between 75% and 85% cost of the whole
unit, that is why I posted normally the item will be uneconomical to repair.

And you accept that as "fact"? If the set operates normally and a close
inspection shows no physical damage to the underlying plasma panel, wouldn't
you just replace the protective screen if it were your TV rather than spending
$5,000 or more to replace the set?

Good point, Sam. Too often, we fail to recognize the difference between
assumption and fact.

There was a scrap dealer in my hometown with the slogan, "one man's trash is
another man's treasure."

Re how damaged it was!

Some object by the owners lads being thrown across the room caught the lower
middle edge of the glass & frame. A small crackof perhaps 2-3 inches
appeared. The set continued to work ok for some 3 months until the crack had
propagated across most of the front- as glass tends to do. The front glass
to the pdp itself has not been touched, cracked etc. and the front filter
sits 10mm away from it. Nor is the filter 'sealed in' in any way, so I don't
believe there is any safety risk etc

AW

BTW: I did not say that Samuel! Just denoting information that we are
requested to inform the customers of if the products is still under
manufacturer's warrenty. Also, Leonard, I have a hard time assuming
anything, I personally presume until proven otherwise, teachable: yes!
opinioned: occasionally, wrong: of course (We are all still human): open to
public correction: We had all better be, inclusive of myself!
These items possibly may be serviced in many other manners that what we
have been trained to do however, when dealing with multiple items, still
under manufacturer's warranty, we tend to follow their specific
directives. When they are completely out of warranty and have no other
options to mitigate costs to consumers then the other options are
evaluated and discussed with the customers. This pertains to all type of
repairs, not specifically these "High End" Displays.
Thanks again Gents; Cheers

Hi Andrew,

At first glance it seems a bit expensive. When I convert it from Pounds into
local currency it's looks as if you've been quoted retail price...

After some googling I think the customer paid over UK£5000 for this unit
when it was new? If so, £843 for the 'Screen Filter' sounds about right.

Hope this helps,

Sure is!

It can be fun trying to talk someone through stripping down a unit etc on
