Try a reset to this TV first. If it do not help you, the firmware to it is corrupted. Contact the authorized service centre; if this is the case.
To make it a hard reset, just unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. This procedure will make it a hard reset. If you want to make it a system reset [Factory Reset]; you have to enter its service mode option, and select the factory reset option. If you wish to get some details; check the site linked here. Pull up older posts. Surf the site with patience. http://electronicshelponline.blogspot.com/
Service mode entry, adjust and exit procedure to many popular brand TVs are given. Never forget to exit the service mode, after all adjustments have been done.

It may have detected over current draw due to something is going out in your TV or the power supply module may be dying due to bad caps, cold solder joints so it goes into shutdown mode to protect itself from further damages.
In any case, you will need to open it up and do in-depth troubleshooting.
Please read my guide to understand how LCD TV works first.

Analog out of range


The TV maxes at a 60Hz refresh rate, and the game refreshes at a 120Hz refresh rate - common problem for that game and this TV - you will have to change the game resoltuion to 480i or 480p from the gaming system/pc itself (or change pc refresh rate to 60Hz, and 480 X whatever reoslution).
