I believe it is a Back Light failure. Either because of a bad Ballast, a Power Supply, or a bad Lamp that is not replaceable. If it is a bad Ballast or Power Supply they are replaceable. Checking the Voltage from the Power Supply for the Ballast will tell if the Power Supply is bad. It should read around 250V to 300V.
If the Voltage is there, the LCD Panel will probably need to be replaced. I recommend a professional to evaluate it to be sure.
I hope this helps,

If the TV keeps shutting down and goes in standby, then the TV is going on protect mode after detecting a malfuncion.
When this happensthe TV gets shut down to prevent further damage to internal components.
Before calling support ensure that you have followed the indications here Why my TV does not start up and remains in standby.
Troubleshooting basically consists in leaving the TV unplugged to drain power completely and discharge internal circuits. Instructions are for a DLP, but procedure is the same with any TV, even plasma TV.
The best way to contact an authorized technician is by ringing the number listed on the owners manual. Alternatively try Fixya directory here:Fixya directory- Consumer Products Repair
Try first the troubleshooting proposed in link above. If that does not work, ring customer service.
Regarding the rpair cost, this depends on the part that is defective. A common fault is the power supply, but this is not necessarily the problem.
