This is a 55 inch Samsung smart LED TV model un55mu6300f that is totally dead. That means there is no picture, no sound, no standby light at the bottom, no nothing. Typically televisions have a 3.3 Volt or a 5 Volt standby voltage on the Power Supply board which should be present at plug-in. But this particular model television uses an 8 Volt Standby voltage which changes to 13 Volts when the TV is powered on. We find this Voltage to be Faulty which indicates that we have a bad Power supply board (BN44-00807A).
