Because of that high pitched whirling sound I am willing to bet it is time to replace the colorwheel. What is happening is that once a fault in the colorwheel is detected by the dmd, it is cutting the power supply to the ballast and hence not powering up the lamp. Unfortunately one has to know this since even though the color wheel is a consumable part sold online everywhere, there is no "colorwheel error light" on the TV...
I can suggest you take the back cover off and physically inspect the colorwheel, depending on how tech savvy you are.. I hope this helps!
