The lamp finally went out in my Zenith DSV100. While I am waiting for the lamp to be refurbed and sent back to me, I was wondering if there are any modifications anyone knows of that will improve image quality. I believe this is the same as a Davis DLS8. I've heard of blocking out the clear portion of the color wheel. What is the best way to do this and what will I gain from it? Are there any other mods that people are aware of?
