The power supply in these sets is running all the time whether it's on or not.

I fixed a 32" 2007 Samsung back in 2011 by replacing one swollen cap in the PS, it's still working.

When it's off I can hear the PS singing (it's mounted at ear level), it sounds a bit like the Flyback whine in a CRT set.
