SOURCE: 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.

SOURCE: Removing a screen protector from a Hitachi 50UX58B Projection color TV

There is a black plastic strip that fits into the groove at the top of the frame holding the protector and front screen. Pull that down and out (you might need to pry a little to get it started). The attached picture shows the strip partially pulled out at the right edge (photo depicts the top right of a 58K - with a wood cabinet).ea84b4b.jpg
Once this strip is removed, you should be able to see a gap (~2mm) between the top of the protector and the frame. Pull the middle of the protector toward you (you may need to hook it with something like a chrochet hook to get it out to where you can get a finger on it). Pull out one side of the protector, then work it loose fromt he bottom. (If it is stubborn, you may have to loosen the bottom frame. Take of the speaker grill, then unscrew the screw on the bottom of the surround for the control panel and pop the surround out. Then there are 3 screws that hold the cabinet frame {might me different for the 58B} and beneath that, 3 screws that hold the bottom of the inside frame. Once those are removed, you should be able to flex the inside frame enough to loosen the protector.)

Installation is the reverse. There are two grooves (at least on my set), and the protector goes in the rear groove(!) (same as the screen itself - first time I tried to put it in the unused groove closer to the front of the screen, and that iddn't work). The black plastic retainer strip goes in the front groove.

My toshiba 57 inch rear projection tv every once in awhile makes a loud pop similar to a spark noise and the screen either goes black or flickers. do you have any suggestions what is causing this??


THis could be one of the CRTs (Color Tubes) is bad or the high voltage is leaking somewhere.
Toshiba projection TVs have history of yoke problems.
My guess is one of the CRTs is arcing inside. This TV has 3 CRTs red, green and blue. Replacing a CRT is not easy or cheap to buy if you can find it. If you like this try calling a TV technician to track down the high voltage arcing. DO NOT TRY TO DO THIS BY YOURSELF.

Best of luck my friend.
