Question about Sanyo PLC-SU50 Multimedia Projector
You are describing Color Decay. Welcome to the world of LCD projectors. The blue device is the first to go, thus the yellow fringe. You must have about 3-4000 hours on the projector. Replace the product with a dlp product and it will last a lifetime, or until you want something with newer features.
