Hi @

What is the ''AC voltage'' at the fuse FP8015 (if this is the one you meant) as the meter may have given an incorrect reading if measuring for DC volts as there are none there?

''Be safety aware as it should be lethal AC supply voltage value''

Try the following:

Disconnect the power from the TV.

Remove the back cover from the TV and then disconnect the cable between the mainboard and the power board.

Reconnect  the power to the TV.

The TV backlights should turn on full intensity and stay on. There will be no picture because the mnainboard is disconnected

''If they don't come on or if they blink'' then there is a problem with either the power board or the LED backlights.

''If they come on and stay on'', measure the DC voltages at the connector on the power board where the mainboard cable was connected to and make sure that they’re all OK

Measure between an earth point (screwhead on power board) and the pin. The voltage values should be marked on the power board near to the connector.
