What's best for cleaning a Projection TV screen filter? There seems to be something on the inside part of the screen. I've removed it but I want to make sure I use an appropriate substance, that would damage the screen.

Re: TV Projection filter screen
I would not use any kind of chemicals on the screens, I definitely would not use any liquids on anything besides the screen protector, the inside screen is a Fresnel lens and will wick up moisture, the one with the vertical grooves is the Lenticular and either one will leave a mark, if you have to use liqud, I would try distilled water, but no guarrantees you will get it clean. I usually end up replacing the screens. Looking at your post you said filter, do you mean an air filter? I dont think these sets us an air filter, if it was just dust a t-shirt or microfiber towel usually work, the towel being my choice.

No one seems to know what they are talking about when it comes to this issue. I had the same problem for a couple of months. I looked up and down the internet for answers and manuals and came out empty handed. I didnt want to pay a repair guy so i decided to take on this filter problem myself. The OSD should say Projector Fan Filter Unit Needs Cleaning. The fan filter unit they are talking about is on the projector itself. That means you have to remove the back panel. I placed the tv on a blanket screen side down. Revome the board inside the stainless case and remove the projector unit. You have to unplug a few cables...thin gauge wires so be careful. Underneith and on the side of the projector are two foam filters. I vacuumed the heck out of them and its been working fine. You could try getting away with removing the front panel to the right of the lamp. you will see the small foam filter to the left of the projector but there is another one under the projector. Try vacuuming the best you can. My tv was pretty dusty inside so I'm glad to dug in a little deeper.
On each side of the set is a round access panel.
Remove the oblong style cover to get to the screw that holds the round door on.
You should have access through the hole once the hole cover is removed.
Don't spray anything inside and cleaning should be done with a dry soft cloth.
