Hello, I just recieved one of these TV's from a relative and noticed that my picture quality was a little faded. I figured that was how many of the older Projection TV's would show and never thought about anything else. A couple of days ago I was thinking about how to troubleshoot the internal speakers (I have a problem with all four speakers where no sound is produced, but I can hook the TV up to my A/V receiver and it works just fine), I took off the rear cover (about 20 screws) and noticed a bunch of dust covering everything. The first thing I did was get a baby wipe and a soft dry cloth and cleaned the 3 lenses. I then turned on the TV and WOW! What a surprise! It was bright and sharp and clear from edge to edge. I can even see the picture when I'm standing parallel to the screen! I suppose this is all you will need to do, however, I am going to go one step further and remove the dust layer on all the other components also. Hope this helps. -G
