My Samsung DLP (5063W) is making a buzzing noise on startup. The noise goes away after several minutes. I've read that this could be the color wheel, but if it is wouldn't the noise be constant and not go away?
I had this problem with an HLN567 and it was the color wheel. The technician that replace the color wheel said that it was the wheel was intermittently loosing speed. My set also would intermittently turn off before I had the wheel replaced.
