hi,
Yor tv has problem with back lighting. This tv uses LED (Light Emitting Diodes) as back light. These back light modules are not availabe in the maket now. You have to contact the authorised servicing centre for the same. You will get an idea how it works by the help of following picture.

If totally dead it appears to be a power supply issue.

This will be your Y SUSTAIN board on the left hand side when you take the back off.
Plenty available on ebay, Very easy fix

Main systme control PCB. its the board where all of your inputs are in.

Thats the PIP (picture in picture), which lets you watch two pictures at once.  Push the PIP remote or go into the settings to turn the box off.

sound like the inverter circuit board problem. check & replace back same part# inverter circuit board. hopefully could help!!

I have a 42" LG LCD TV and just experienced this today. Watching cable, then the screen went to black, but audio continued. I pressed the guide button on my remote and pic came on with my guide menu. But then went to black again 10sec later and has remained that way for nearly an hour. Tried switching off both cable box and TV, disconnecting and reconnecting cables, but no luck. Finally unplugged mains, waited a minute, then turned back on. Everything seems normal now after the reboot. Phew.
