To answer your question;
Strange coincidence but i repaired the same tv model that you have yesterday and for the exact same problem so here`s the fix;
In your power supply on the 5volts line there is two 3300mfds/10volts capacitors gone bad and that caused the voltage to drop to 4 volts(not enough to shutdown the set but enough to kill the video)
You`ll recognize these capacitors by a rounded top and some fluid that leaked out, you can replace them with 3300mfds/16volts since the 10 volts variety is harder to find.
And while your at it you should inspect and replace the other capacitors in that area that have the same look
Good luck and keep me posted

SOURCE: Just bought an LG Plasma
The tv is faulty and the fact that it failed immediately after you have started it for the first time is a clear indication of a manufacturing defect.
Take the tv back to the seller and ask for a replacement one or your money back.

A backlight will either not light because of no voltage or no control (not being switched on by the set).
