Question about Optoma HD70 DLP Projector
If you hear chirping, too, replace the colorwheel. also check the lamp timer. if it's close to 2000hours (or the inside of the lamp is bulging or blackened), replace the lamp. if the lamp is new and the colorwheel doesn't chirp, replace the ballast/power supply.

Sounds like your system needs a good clean out mine did the same and I took it apart and cleaned everything inside fan, colour wheel, lenses, boards, vents the lot, it fixed my flickering problem and now runs great.
