Sounds like main system control memory IC fault. Anyway, try a reset to this set first. If it do not help you, contact any service technician to replace this IC.
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.
