Plasma screen repair question...

[none]

I've got a JVC 15 inch plasma screen tv on my bench for service that
went through the flood in New Orleans.(Katrina)
It was under water for some time and of course the screen assembly has
suffered severe water intrusion.( bubbling in between the laminated
screen as well as some water streaking in backlight unit.)
I'm trying to fix this for a friend that purchased it just weeks
before the flood.( and at a cost of just over a grand!)
I've pulled the unit completely apart and the electronics seem
salvagable, only a bit of crusting that washed off with board washer
easily.
My question to any experienced in servicing plasma's is are the screen
and backlight units cost effective to replace?
The one's in this JVC are made by Phillips.
I can post the specific part #'s off the parts if it's worthwile.
TIA for any info.

The plasma screens are rarely available as in individual part even on
the small units. When they are available the plasma screen generally
costs as much as a new replacement unit.

Electronics under salt and waste laden water salvageable?
More than likely the electronics is actually toast. You cannot see the
damage to the via , the penetration into the surface mount components
of the water, etc.

Plasma screen? Or do you mean LCD? They're two entirely different things, if
there's water inside a plasma panel it's lost it's vacuum and the unit is
junk. If it's LCD, they have several layers of plastic diffusers and filters
stacked together around the panel, sometimes you can dissasemble those to
clean and dry them out then put it back together but that's about all you
can do, the display panel is the bulk of the cost of the unit and hence not
available as a spare part. If you can't fix it the unit is scrap.

I don't think there is a 15" plasma made....only LCD

Entire display panel is probably in need of replacement......usually costs
as much as the unit itself!

You stick the wet circuit boards in a dehumidifier cabinet. It'll suck
out all the moisture from the components, at least that's how we did
reclamation in the Navy.( Salvaged alot of avionic components from
downed aircraft and such that way.)

Thanks for the reply. I kinda figured it was a long shot on the plasma
module.

Yep. it's a plasma. It spent about two week under water contaminated
with all sorts of industrial chemicals, so that explains why the
seals went.(Everything in the locale of the flood had a coating of tar
like gunk and stunk to high hell of petroleum.)

It's a plasma for sure. I didn't think they bothered to make 'em that
small either.
The owner will just have to write it off on their insurance and get
another, a shame it being so new.

What's the model number? I looked around and can't find reference to a
plasma set that small, I'd be curious to see one.

You said in your OP it has backlights. Plasmas don't have backlights, if it
has backlights it surely has to be an LCD. Come to think of it, I don't
think Plasmas have laminated screen layers either. What gives you the
impression it's a plasma?

It says so on the case.
