Question about JVC LT42P789 42 in. LCD TV
Yes, you got a major failure in the power source. Since it's related to the high tension for the panel and you heard a popping sound (most surely a capacitor going out in a big way) you should check all components on it - starting with the capacitors (replace them all to be sure) and the power transistor. Don't forget to check the main transformer and the board under it, it may be burned.
