They are within 3% so they are fine.
Do you see the screen flash on for seconds?

Do you see the screen flash? maybe try in a dark room just too see if the baclights do flash at all as maybe a faulty tube etc

I am talking about the backlights inside the LCD panel, not the indicator lights.

Checked VCC to inverter also what about the fuse ?

Re: Samsung Lt-t32a transformer

The board with the high Voltage inverter transformer is just transformer board, the transformer drive circuit is on the power supply board.
So you need to find out first if the power supply is getting the command signal from the main board to turn on the power supply and the inverter circuit.
