Question about Zenith Z46Z83D 46" Rear Projection Television
When the set is first turned on the picture is fine. After being on for about 30 minutes, the picture gradually becomes very blurry. If the set is turned off for about an hour, the picture is clear again. But after another 30 minutes or so, the blurriness returns.
It sounds like the focus block or flyback is bad.sometimes you can put nail polish on the adjustments controls to make it stay.usually they are marked from the factory with white marks check and see if they are aligned.but be sure somebody with tech-skills help you.the flyback usually has a screen & focus control.(the big red wire to the tubes or block)
