| Remove the speaker grill and take out the screws and disconnect the wires to remove the screen assembly. | |

|
| I just purchased this Hitachi 50 inch rear projection 50ux23k- used--- from a friend. Now that I have it home- when I'm viewing it, I'm seeing dark/shadow circles on the screen... it's more visable when I'm watching a hockey game (or something with a lighter background).
The circle starts in the middle--- then another circle around that...etc... it extends to the ends of the screen... each circle is about 1 inch thick. What does this mean? Can I open up the back and clean out the dust? Any suggestions would be helpful. |
