Hi.

First check if you have on screen menu and if the problem is still there if you change input source and cables.

If TV has no backlight on all inputs, then it is either inverter not supplying power to the backlight system, or the LCD panel itself.

No picture but has sound

The problem can be caused by a bad sustain board (Ysus Zsus) , the popping sound is often caused by a capacitor blowing up.
The TV must be taken apart and tested before eventually replacing sustain boards.
