This a factory issue and usually requires service. Most cases it is a bad power supply caused by a surge or powering off and on too fast ... sorry I wish I had better news

The weird sound was caused by the power source being so overstressed that the emergency shutdown was engaged. This is what happened: a part inside your tv was failing and, when you tried to start the tv, the sudden electric shock caused by the starting of the power source has been too much so it finally failed in a big way - it shorted. This short has caused a big spike it the current drawn from the power source, way more that it's designed to deliver normally - generating the sound you heard. This spike in the current has triggered the protection system into action - the power source has been forcefully shut down.
Since the protection system is now activated the only way to reset it is to eliminate the short. The only way to do that is to open the tv and test the components, find the failed one and replace it - a job for a skilled repair man.
