First check if the TV responds by pressing any other button except the Power button, on the TV (on the back, right side) or the remote control.
''If the TV does respond'' e.g. audio, images etc try a power refresh and check if this resolves the problem. Turn off and remove the power from the TV and then ''press and hold'' the TV’s Power button (on right side, back of TV) for a ''full 30 seconds'' and then release it. Reconnect the power to the TV and try turning it on etc.
''If the TV does not respond'', no Standby light is indicative of no power being received by the mainboard from the power board.
First check that the fuse (T3.15A 250V) is OK, by disconnecting the power to the TV and testing the fuse for continuity with an Ohmmeter. (see image below)
''If the fuse is OK'' there is a problem with the power board.
Check that there is +13V power on the testpoint on the cold side of the power board (see image below)
If there is no +13V check that the diodes as marked in the image are OK and not short circuit or open circuit.

''If the fuse is blown,'' you need to replace it with a T3.15A 250V ''slow blow fuse (''as indicated by the ''T'' in the fuse specs). A standard fast acting fuse will blow as soon as the power is connected to the TV due to the initial high inrush current, whereas a slow blow fuse will hold. Be aware that if the fuse is blown, that there is always a reason for this, so this will have to be further investigated. It may be prudent to purchase 2-3 fuses.
***Be safety aware*** ''when working/testing in the back of the TV with the power connected, as there is'' e***xposed lethal AC voltage*** ''present on the power board.''
Alternatively you could just try replacing the power board. Search online for ''Samsung T32E390SX power board'' or ''BN44-00801A PSLF720S07A L32SF_FSM'' (verify that I have got the correct board by comparing this number to what is printed on your power board - if it isn’t the same, search for the full number on your board) to find suppliers that suit you best.
