Default Re: Samsung PN50B650S1F clicks on plug-in with flashing voltages

Okay I just did that. Here's what I see:

The instant the plug makes contact with the prongs PS_ON voltage of 3.28V DC appears. When I hear the first click click PS_ON volts drop to 0.16V DC and return to 3.28 after the second click click, lather rinse repeat.

With the SMPS unhooked from everything but AC volts (wall) and PS_ON grounded the unit remains powered up and does not cycle. Same with VS_ON to STBY, no cycling.
