Question about Sony KV-36XBR450 36" TV
There is problem with the back light of your tv. In LCD tvs CCFL are used as back light to give light to independant pixels.There will be 12 over more CCFL labs behind the lcd screen to provide the brightness. CCLF lamps required high voltage to light. This high voltage is provided by the inverter board inside the tv. If any one of the chopper transformer (high voltage transformer) have some problem then the inverter will shuts off itself preventing damges to the power supply.
You have to check the 24V from the power supply. If its ok the you have to check the inverter board.if avilabe replace the same. if you are not able to do the same i will prefer to consult some one experienced in it. Back light inverter board will look like one in the picture.
