Re: wet screen

You will need to take out the screen from the front of the TV set. Then the screen will be taped together, as it is in two pieces. Clean the screens very carefully and do not forget what way you took them apart. It will make a differance as they are simply not plastic, they are each a special lens. Good Luck

I did something wrong.....

Windex is not the best cleaner. Bed and Bath Beyond has a very good NON-Streak class cleaner that I tell my customers to use. The best solution is NOT to Spray directly onto the TV Screen. Remember the glass is only delivering the picture from an RGB projection unit sitting inside the enclosure. It is not the electronic projector and the screen is separate. It can be replaced if damaged; however I believe it is only streaked and needs proper cleansing. If you get the new cleaner, spray the solution onto a soft cloth and wipe the exterior screen. Promptly wipe it dry and if you need to do this a few times, eventually you will get the glass clear and enjoy the show.

My nephew spray windex on my dlp tv and not is in between both screens n it black but you can move the water still with your fingers

Well I'll say this. There has been no damage done yet. The problem is that the windex has wicked up in between the Lenticular screen and the Fresnel lens screen. If you attempt to seperate both screens yourself then I can guarentee you will damage both screens.
Not cheap to replace both screens. The screens CAN be cleaned with a screen cleaner from Screen Clean but the real problem is finding a Highly qualified technician who has done this many times before. The Fresnel lens screen is EXTREMELY soft and has tiny ridges that damage very very easily and you will see permenant black streaks in the picture. Never use Windex,Amonia or 409 and the like cleaners on the screens. When you use a screen cleaner, spray the cleaner on a MICRO cloth (Very Soft) then carefully clean the scree. Like I said, the screens can be cleaned safely only by a Highly skilled technician. The black spots from the windex will not eventually go away. Contact the tv manufacture as they can direct to a authorized service center they trust.

Liquid under screen on mitsudishi dlp tv

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

Liquid in screen

The screen is two separate pieces of plastic. One is a fresnel screen and the other is a lenticular panel. They act together to disperse the light evenly. Yes the front bezel will come off and the screen will come out. But they are taped together with just a slight air gap between them. The windex was wicked up between the two panels by capillary action of the fluid and space between the panels. Trying to take the screens apart would be easy. The problem is the grooves in the two panels are almost microscopic so any attempt to rub them will leave a mark. Plus unless you have some kind of clean room the slight dust particle or hair that gets left in there will stick out like a sign when it is reassembled and turned on. The only hope to try to correct this is to removed the bezel and then the screens but do not separate them. Then wedge some tooth picks in the very bottom of the edge where the stain is being careful not to push the picks up into the viewing range. Then with a spray bottle of just water try to rinse the windex and wick up the water with a wedge of paper towel just inside the edge. The same action that got the water up there will wick it down.Repeat this several times to delute the windex as mush as you can. It may not get it all away completely but it should make it livable. After the last rinse leave the picks in and left the panels air dry before putting everything back together. The most IMPORTANT thing not to do is to lay the panels flat and flex them, this will allow the two grooved panels to chaff one another and they will be destroyed.
