Loud buzz is the color engine, turning the color wheel. Find instructions on how to take it out and clean it and that should fix that problem.

Loud buzzing sharp


Could be in the power supply, (hear it with sound turned off) or another area like in the optical unit- or even one of the fans.

Need to try by ear to localize where it is coming from---with sound off if a loud buzz look first to power supply and then optical area.

Picture fine for 10min.-then flickers(clicking sound)& then colors gone yellow


Looks like it's a color wheel problem-found a cleaning walkthru online, but it doesn't get rid of the loud hum form the CW motor. Also, it is thermal related-when the colors went out I placed a fan next to the color wheel and everything went back to normal. Several design flaws here and for $3000 these companies should do better-severe problems after a couple years is not acceptable.
