My kids got the liquid from a freezer pac on the tv screen. It seeped under the screen. As it is seeping up the screen is looking black. Any chance this will dry and clear up. It just happened and I wanted to fix it as soon as possible. Can anything be done or is are tv ruined. Please help.
You need to take the screen off the front. You will find the screen comes away from the frame and seperates into two sheets. The liquid is seeping inbetween the two. If you clean it with Meths it should sort it without marking it.

Never spray directly on a screen. If the solution seeps into the underside (back etched side of the glass) it could damage the surface. You may have to get to the inside from the rear projection area or lift of the front glass screen and remove it completely. Usually the Rear surface of the screen is etched and can be wiped clean. Go to Bed Bath and get a good streak less windows cleaner. Spray it on a soft cloth and wipe the front and/or back glass. Wipe dry with a CLOTH, not a paper towel, and when dry use a flash light to see any streaks or blemishes left behind. Clean again is necessary. Do not apply pressure, gently clean and try not to cause scratches as they show up when the projection device flashes the image on the glass portion. Put it all back they way it was and enjoy.
Normaly the two screen are taped together using an axacto knife seperate the screens and use 98% alcohol to clean'em,careful to reinstall the screen exactly as removed and do not scrub very hard as they plastic and can be scratched easely.
There are a few quick fixes you can try. You can leave your tv on 24-7 and put it into the video mode when you are not watching it. This will prevent the problem from getting worse in most cases, as the root fault is usually bad connections on the systems control processor which get worse every time your tv goes from cold to hot.
You can determine if liquid has seeped into the tv, usually by water on the picture tube face. The circuit board needs to be inspected. Cleaning liquid residue with rubbing alcohol and an acid brush should resolve the problem.
Other things that can cause your problem are more involved and would need to be referred to a service provider.
If your having pixelation,try disconnecting other tvs
from the wall.you may have a noise or DB drop off or surge issues.check all splitters from the tube to the soffit of your home.If you find one upside down out side ,water maybe be getting in.Remove all snap adapaptors,screw on only.Splltters are
cheap,,easy way is spend $3 extra a month to have your cable Co repair or replace any seeping cables or adaptors and/or splitters.
With a conventional projection type screen on CRT type televisions this is not a problem,but with the newer DLP type screens the fiber of the Fresnal screen acts like a spounge and soaks up any liquid introduced.If you try to clean it it will smear and make it worse.You can remove the screen assy an clean it with Windex but allow it to dry properly.I do not see a problem with cleaning this screen,but make sure you put the screens back the way they were.I must also note that it is no easy task removing this particular screen assy.Good luck
hi there, well my friend, this rear projector tv has 3 lenses, one that projects red light, one green light and one blue light. the liquid came from those lenses and it helps the light go tru the space. each one has a sensor and if theres not fluid the tv will protect itself and wont turn on.
i'm not to sure if the fluid made any short circuit between components, because is an oily solution and don't have many conductor properties. (correct me if im wrong) but i suggest if you don't have electronic knowledge or skills, don't attempt to repair it yourself, its hard even for experts to remove all the connectors and will take several time to do it.
The cleaner will work. but the liquid if its CRT coolant, and in that model I would bet that it is. Coolant is corrosive so i would at least heat the solder on those components just to evaporate any coolant that has seeped dow the components legs as it can and will eat at the pin/solder connections.
It looks like the service centre guys are trying to get more money out your pocket.
It could be that they under estimated the cost of the repair and base on that they sent the quote to the people that pay for extended warranty repairs and now they are finding out that is costing them more money for the repair. The lamp was not causing that those lines apprearing on the TV, so it did not need to be replaced.
Hope this helps.

It's possible that the cleaning agent in the spray has dissolved the screen.
If it is the lenticular lens(the vertical lines) there will always be
permanent marks from the spray until it is replaced.
You can try a toothbrush, dry and carefully scrape the material out of the grooves.
there's also the Endust Product made just for this type of thing, It's called Endust for Electronics, and I heard it works like a champ.
Another option is a dry-cleaning solvent, trichloro-ethane, which you can find at many hardware stores. This will wipe crayon marks right off of glass without any scrubbing at all. Plus, it's harmless to most plastics.
Also heard of a product called Tough and Tender, that should be ok with a screen.
you better consult JVC on any material you plan to use though.
Major problem is in case the spray dissolved the screen.
