It is either dead 24vdc power supply or shorted out backlight inverter board, those are the two parts you need to check.

My tv powers on and shows a light for a second and then screen turns black, what component is going wrong


You may be having a problem between a connector from the motherboard to the lcd screen. To fix this, you would need to take off the back panel (or have a technician do this if you are not comfortable, or feel safe doing it) and check the connection (probably at the top middle of the back of the lcd screen) If you are getting sound, then this probably is not the problem, but based on the information you have given, this fix should be relatively easy if it is in fact the connection between the circuit in the motherboard and the lcd screen.
