I knew that certain cleaners had to be used, and that Windex and paper towels was not the way to go. So, when I got the HDMI cables I needed to hook my FIOS and my computer up, it came with something called CleanScreen, and a micro fiber cloth. The directions said to hold the bottle about 6 inches from the screen, spray and wipe with the included micro fiber cloth. I did that. It didn't do a good job as it seemed to leave a lot of streaks. So, next up, I got Monster Cable's TV screen cleaning kit. This time I sprayed it on the cloth, wiped carefully-still streaks. The first cleaner has "proprietary polymers" Well, one of them have mucked the screen up. Smudges all over.
But the thing that gets me, when I'm watching the TV, in the upper right corner there looks to be like a streak on the screen...about the length of a finger, slightly crooked. It's really only visible when something light appears on screen, but it's annoying. Is it possible that some of the first cleaner ran down behind the screen? And if so, is it possible to clean the back side of the screen to remove this shadow? Can the screen be removed somehow?
I'm going to go with another mf cloth, and some distilled water to try and clean it again.
It's extremely unlikely that anything would drip into the internal layers but not impossible, I managed a network with over 600 LCD monitors and dozens of LCD TV's. Occasionally I'd get a bad line of monitors and we would disassemble units that failed prematurely to troubleshooting and identify the failure points and there are about 7 layers on most CCFL's but it's rarely that internal dripping to occur. What's more likely is for chemical sprays to damage the outer layer coating of the LCD - you don't need chemicals - distilled water misted on the cloth should work 99% of the time but regular dry use should suffice unless the panel is exposed to smoke, dust, and young childrens tendency to touch everything.
I've tried a dry microfiber cloth, and I've tried another cloth with a mist of distilled water. It's still there.
Here's what I'm talking about. In the upper right hand corner of the picture. Looks like a smudge mark going from top down in a crooked line, like a finger.
Lots of people have looked at this. I hope that somebody will give me an idea on how I can make this go away.
I'm still curious what it is.
Some commercial cleaners will leave smear marks on the panel because of their chemical composition and some can interact with the panel's outer coating leaving smear marks. If you can't remove those by using warm, distilled water and a microfiber or with the eye glass cleaner, there probably isn't anything that you can do. I don't know if this would be covered by any sort of warranty because it's not really a defect in manufacturing, unless you say it just appeared after a period of time I have a two-year old LG and have used the water/microfiber/Swifter Sweeper cleaning/dusting methods and my panel looks the way it did when I first took the LG out of it's box.

Black streaks on LCD screens are visible against light backgrounds.
Dark streaks on most liquid crystal displays (LCDs) tend to be manufacturing defects. Although it is possible to experience temporary image retention on an LCD, this usually goes away with normal use. Dark streaks can plague any brand, visible when the screen displays a light-coloured background. Technically known as birefringent streaking, it is one of the most-noticeable and annoying LCD screen defects. Black streaks are possible on any sized LCD screen, from televisions to portable devices.
And that describes perfectly what I encounter. The TV picture overall is beautiful, and I only see this when that part of the screen is lighter. I've never used anything but approved cleaners on the screen, so it's nothing I did. And since I have a 4 year warranty that covers defects, I can get a new screen. Yay!
I have a question. I was sitting here this morning when I see a small gnat crawling on my screen. I use a 24 inch Orion lcd for a pc monitor. Anyway, I try to brush it off only to find it's not on the outside of the screen. So I'm thinking it must be some Facebook Halloween stunt or something. I push against the lcd a little only to end up squishing said gnat. Now I have a dead gnat sitting in the lower right hand corner of my screen...all the time. Is there a way to clean it out of there?
got exactly the same issue... pressed on this small bug just to find out it was inside the screen and got stuck in there, really annoying.
Have anyone managed clean the panel from the inside?
If I will find a simpler solution for the dead gnats inside the screen, which I found is a very common problem, I'll post here
