Cleaned 46HM95 screen with electronic safe DLP screen cleaner. Solution dripped down underneath screen by the Toshiba emblem. the screen is now clean and dry but now there is a black smudge, almost looks like a ink smear, spread across bottom portion of screen. The liquid solution moves when the display is pressed, which is trapped inside the screen. The smudge seems to be disappearing, as the solution could be evaporating. Otherwise the picture is good. Any ideas besides don't let cleaning solution run down to bottom of screen and collect??

do not use Windex. Or any other ammonia-based product. Trust me, ammonia and TV's is not a good combination.Chances are, your instruction manual agrees with me too.That Office Depot Screen Cleaner, along with many others out there, is
safe to use - gentle on the screen - and will do a great job at
cleaning.Usually that stuff will be < $25 for a decently sized bottle that
should last about 3 years for a 50" screen that gets cleaned weekly.
Most come with a micro-fibre cloth too. Overall not a bad investment. Will work great on the smoke residue on your tv - along with any
computer screens and anything else in the house. Definately worth
How Can I Clean The Fingerprints Off The Screen On My TV?To clean fingerprints and greasy smudges off your TV screen, first try using a dry, anti-static cloth and rubbing gently. Note: Many Samsung TVs come with a screen cleaning cloth. Use that cloth and follow the directions on the package. If that does not work, get a bottle of ScreenClean screen cleaning solution or similar screen cleaner. You should be able to get it at most regular and on-line stores that sell monitors or TVs. Put a small amount of ScreenClean on a clean, soft, dry cloth, and then rub the screen gently. WARNING: Never use any type of window cleaner, soap, scouring powder, or any cleanser with solvents such as alcohol, benzene, ammonia, or paint thinner. Never use abrasive pads or paper towels. If you do, you can scratch the screen or strip the anti-glare coating off the screen and cause permanent damage.
Cleaning It Right
There are four steps you must take to do the job right:
Unplug your TV before you begin to eliminate the risk of electric shock.
If you use ScreenClean or a similar screen cleaner, put or spray the ScreenClean onto the cloth. Never put or spray it directly onto your TV screen.
Wipe as gently as possible. LCD, Plasma, and DLP screens in particular are fragile and can be damaged if you press too hard.
Let the screen dry completely before you plug the TV back in.
Food and DLP Screens
Getting sticky food such as peanut butter or jelly off the screen of a DLP TV is especially difficult because the tiny grooves in the screen's surface trap small food particles. In fact, you probably will not be able to remove the food entirely. If you need to remove sticky food from your DLP TV screen, follow the directions above, be patient, wipe gently, take additional time, and understand that you will almost certainly leave some food residue on the screen.
can you feel if the surface is rough has it been cleaned with an abrasive cloth like a scouring cloth used for dishes as this will scratch the surface of the screen try getting a good polish spray on but dont spray to much on and use a soft cloth ideally a proper duster cloth see if they polish out if not the the screen surface has been scratched this can be polished out but you will need to get a pro to do this as doing it your self could ruin the telly permanenty as this is a delicate job to do hopefully you should polish these marks off but if not i would get somebody out to look at the telly to get the scratches polished out of the screen this should not cost to much but will save the frustration of watching a smuged screen the only thing you can do yourself is try polishing the screen properly in case she cleaned it and the cleaning product is still on screen if not you will need to get the screen profesionally polished goto a tv repair shop and these should tell you who to call hope this is some help to you but their isnt much you can do yourself
You need your optics cleaned. To be more specific, your projection lens. This is an easy repair which works best with long arms. All you need to do is remove the screws around the screen frame, then pull the screen frame and rear cover apart a few inches on the top. It will give a bit, but don't try to yank it. Then stand on a chair and reach down into the cabinet from the top with a micro fiber or a clean cotton cloth and wipe the dust off the lens. Don't scrub it, treat it like a automobile finish... gentle. It's ok to do this with the TV on, as you need to see the results as you clean it up. Becareful not to touch the big mirror in the back, you'll see any smudges in the picture. I hope this helps.
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.
Most likely cause of your trouble is dust on the small mirror inside you set. Your DLP set has 2 mirrors not including the DLP chip itself which has about 500,000 tiny mirrors. The 2 mirrors reflect the DLP chip image to the screen you view. The first is the main suspect it's about 4inches by 7inches. It's mounted on the bottom center facing backwards. This mirror faces slightly up and somtimes after time dust, smoke, dirt settles on it . The second fills the space of the entire back of the cabinet but it faces down and takes alot longer to get dirty. The compartment is sealed but dust seems to find it's way in. If you remove the screws that secure the screen assembly from the top , sides and bottom. Make sure to have a friend available the screen assembly is delicate when it's not mounted to the cabinet. You can remove and clean the mirrors. These mirrors are glass and you can use glass cleaned. Don't use glass cleaner on the screen it's plastic. You can clean it if necessary with plastic cleaner only. Probably not needed. Good luck.
my tv repair man said use a blackboard eraser and rub it on screen vertically - that is up & down only. He said to use no chemicals or cleaners, or you'll ruin it. He had a customer that had a child draw on it with crayons-he told her to leave it there because it's better than destroying the screen.
If they are grease marks you can use a warm water a soft cloth like a t-shirt and little dish washing liquid. Gentley wipe the area only stroking down or up--- NEVER SIDE TO SIDE---. Have a dry cloth ready if you drip water down the screen. Now if those are scuff marks, your done, they cannot be removed. They are like the old record albums with the grooves, once the grooves get distorted that's it. Good luck.
