If you are receiving a shrieking noise during powering up the DLP and it last for several minutes its probably this device:

The noise I was hearing was on this board. It would make since because it provides the power to run the DLP. My DLP tube was about 4 years old and its still working but I am receiving the noise during powering up. Even though I was formerly a TV Technician over 10 years ago back in the CRT Days and technology has changed rapidly since those days so I am no expert anymore. I can’t say how long these DLP bulbs last but don’t expect 10 years and more. They were not designed for longevity but for image quality.
