I have a 6 month old JVC 56FN97 that has developed a dark spot across the bottom of the screen that seems as though the screen is delaminated or something can it be fixed?
Figured it out... this may help you, doing it from memory so I
may have the number of screws off a bit, but the rest is
It was windex (thanks to my kids). Here's how to fix it (on a
JVC HD-56fn97). The key is to get to the windex before it's had a
chance to react with the plastic and leave a white haze on it. I
did all of this within 6 hours of the "incident" and the screen is
fine, there is no trace of a problem - AT ALL.
1. Remove speaker trim from front of TV on the bottom, there's a
couple tabs that you can find by feeling around... press them the
trim comes right off.
2. Remove the screws holding the speaker enclosure to the bottom
of the cabinet (approximately 6-8 screws) and carefully lower the
enclosure - the wires for the speakers are kind of short, you might
want help so you don't drop the enclosure and damage the wires etc.
Unplug the wires connected to the speakers - the right side wires
are black and red, the left side are whithe and black. (Don't worry
about which goes where, the connectors are different sizes, they
only go back on one way.)
3. Take the screws out of the back of the screen trim
(approximately 8) - BE CAREFUL not to drop the screen - the plastic
trim will break... this is not heavy but it is a little flimsy.
4. Lay the screen trim (with the screen in it) on a large flat
surface big enough to support the whole thing. Don't put it on the
floor, you want something that is going to be clean, lint free,
dirt / grease free, etc.
5. Unscrew the 4 screen retainers on the inside of the trim...
there are 2 sliver colored screws at the top and bottom of both the
left and rtight sides (total of 8 silver colored screws) and 2-4
black screws in the meddile of each side.
6. Lift out the screens (there are 2 and they are taped
together. Carefully cut the tape at the side and bottom, leave the
top tape intact.
7. Use a lint free cloth to dry the windex most of the way...
the big spots mostly. BE CAREFUL NOT TO WIPE / RUB TOO HARD - the
screens have a texture to them that you can't mess up or it'll
affect the picture. Get a hair dryer and blow COOL air across the
screens to dry the windex all the way.
Get another lint free rag and wet it with clean water, not
sopping wet, but a little more than damp. Use the wet rag to wipe
the entire screen down, in the pattern following the texture (one
is random, one is circular). Make sure to get the windexed parts
good. Use the hair dryer to dry it them completely.
You need to be careful to get all finger prints off the insides
of the screens - (oils on your fingers will leave finger prints...
I used a third lint free rag to hold the screens with to avoid
getting finger prints, etc on them). You also need to make sure you
get all the dust , lint, etc off the insides of the screens, when
you put them back together they'll be trapped in the screens and
Put the screens back together and re-tape the sides so that they
stay straight, tec. I used the skinny scotch tape. Wipe down the
side of the screen that will face the back of the tv so you won't
have any finger prints, dust, etc on the inside surface. (Note -
the silver side goes in the TV, the dark side goes out.) Be careful
not to touch the mirror inside or antyhing else, you may even want
to blow the hair dryer in there and get out any dust, etc that is
in there before you put everything back together.
8. Re-assemble the tv the opposite of taking it apart. Be
careful that you put the screen retainers from step 5 back in the
right order of the screw hole won't line up right. The side go in
first then the top and bottom.
You should probably have someone help you with this, a second
set of hands isn't required, but makes removing / installing the
screen, etc much easier.
This whole process took me 5 hours, but I was going VERY slow so
as not to break anything, and about half of that time was spent
just figuring out how to take the screen off.
You could possibly put a small bead of silicon caulk along the
edges of the screen (on the retainers in step 5) to prevent this
from happening again ( a VERY SMALL bead of caulk) but I don't know
if that will affect the screen or make it harder to remove the
screen in the off chance that you have to do this again.
