My two an a half year old got hold of pledge orange oil and tried to "clean" the TV screen. The oil dripped down and is trapped behind the screen. Now there is a black blotch at the bottom of the screen. What should I do?

Re: Black blotch on bottom of screen
If you can take the screen out , then use some dish soap,rag and water to clean the black blotch
if that don't work you may need to use something a little stronger , but not enough to hurt the screen
please rate a fixya and I'll be happy to assist you in the cleaning process and care of the screen

It's possible the mirror has dome dust on it from jostling during the move. W dried water spot will do it too. The front screen will come off by removing the screws on the bezel. Be extremely careful cleaning the mirror.Any scratch by a cleaning cloth (never use paper) will permanently ruin it.
Thanks for your reply. The only thing that causes marks like that is usually the glue that holds the lenticular screen and the fresnal lens together heats up and drips (or slides) down. There is usually a strip of black tape that seals the two pieces of thin, glass sheets. This allows for easier installation and keeps debris from getting between screen and lens, however, someone overlooked the elements of heat and aging on this tape.The screen and lens can either be replaced or disassembled and cleaned. They are very expensive, (a few hundred dollars each), and disassembly can be very tedious. One caution I must give you is to make sure if you seperate the screen and lens make sure they go back together facing the same way. Try to clean only with warm water and a few drops of a very mild cleanser like dawn. If all else fails, you can buy a used screen sometimes from a local factory authorized service center. Occasionally they save the ones that are in decent shape. I have one 57" screen here in cincinnati that would work. Good luck, Russmann.
yes you can clean it. i clean mine all the time. after you remove the screws at the bottom you should be able to just lift it up. it will be hard be cause there is sticky tape with a hinge that the hole screen sould just lift off. i know it doesnt feel like it but it will. just do one side at a time. now the problem with the purple spots are because you move a speaker to close to the front of the tv the was not shielded and cause it to do this. you can move the tv so that the earths magnetic field will restore it for you. make sure the tv is not plugged in when you move it for 2 to 3 days . after the 2 to 3 days plug tv back in and leave on for 2 hours. after this you can move it back and plug back in. this should fix it. if not you will need it to be degoudged. tv repair center can do this at your home. hope this help you.... thanks eddy
Unplug TV, let it set unpluged for maybe a half hour or more (Just for safety) Pop off the speaker covers in the front of your TV, then remove the four screws under each cover, this will will remove the bottem face plate between the two speaker covers, then under that you find (I think four) more screws to remove just under the screen. Now if it is a BIG screen find someone to help you slide the screen up about two inches so that it will be released from the hooks on the inside. The screen is not at all heavy ( less than 5-10 Lb's) just flimsy and aqward. The screen is just a plastic frame holding two very thin plastic screens, one is a magnifing glass the other is vertical lines. If you must remove these from the frame,then as you remove the screen frame from the TV lay it face down and then remove the screws from the inside of the frame, Pay close attention to the way they come out if you put either one of them in backwards it will distort your picture and you will have to do the whole thing over again. The whole thing should only need a philips screwdriver and a half hour of time. GOOD LUCK.
if its is viewable when off then yes its water or oil.between the screens.these screen don't normally come off from the front. they have to be access from the rear. could be big job. only way to tell is to remove the rear cover.
This is probably caused by dust, either on the mirror, lens, or possibly inside the light engine. There is a 5" dia hole on the side of the back of the tv where you can take out one screw and take the door off. this is just big enough for you to put your hand through to clean the mirror and lens. Hope this helps.
usually these are caused by cleaning the screen with a damp cloth or fkuid rear projection tv's usually have two plastic screens separated by about quarter inch with bulbs between,one being a magnified screen.problem is,condensation can occur causing various blotches,letting the screens naturly dry out usually solves this but failing this you have to strip down and wipe them with clean dry cloth.be careful though the inside screen is very delicate.
I just fixed the problem on my epson 57" living station. The picture is like new. Yo have to clean the dust off of the the 3 lcd lenses. (I'm not sure if thay are actually called lenses)
You can get to these by entering thru the front of the TV. Yes the front. You must remove the screen. There are A LOT of screws. This screen housing covers the entire front of the tv. and you have to remove the back panel and ALL the screws on the back of the tv to get it off. The only electronics that have to be disconnected are the Speakers and the front control panel. They both have snap connectors. After you remove the entire front panel which houses the screen and expose the inside mirror you will see more screws. You must remove those as well to remove the mirror housing. DO NOT REMOVE THE MIRROR FROM THE HOUSING. Note that there is a peg that is next to a screw in thre front of the mirror housing thst you must pull the plastic housing out in that area to release it.After you remove the mirror housing you will see the 3 LCD panels or lenses. YOU DO NOT HAVE TO REMOVE ANY ELECTRONICS OR SCREWS AT THIS POINT. Use a can of compessed air to spray the dust out of this area. I used a vacume to catch the dust as it flew out in the air. Try to hold the can as upright as possible.Keep hitting it with the air until no more dust comes out. Put the tv back together. As you open up the tv you will see dust everywhere. I took the oppurtunity to clean as much as I could. The Mirror though was clean an I was afraid to touch it.
I am a Construction Salesman yet fairly handy. I have no electricle experience. This took me 2 1/2 hrs. I spent the first 45 min. trying to get to the lcd panels from the back of the tv. Don't waste your time. You can't.
