Question about Televison & Video
I just received a big screen TV for free. when turned it on and adjusted the settings after cleaning it out, i found that there was a big circle in the middle of the screen. so i cleaned the RBG projection lenses, and the mirror that projects the image onto the TV. when that did not help i took the screen off. i noticed the screen was encoded with tons of tiny unseeable circles. i tried to clean them but it did not affect it. any sudgestions on how to clean it or fix it? and if not where i can get a new 52 Inch screen for it.

it's fairly easy to remove the screws on the back bottom portion of any rear-projector television. when the bottom part is removed, you will see both the mirror and the 3 lens. isopropyl alcohol or windex should do an efficient job. a soft lens rag can be found at any camera store. i'd spray the lens rag instead of the actual lens or mirror when doing this job.
