Your TV could be interpreting infrared noise from your remote as an "On" command. The power button on the remote or the TV itself could be stuck.https://www.quora.com/Why-would-a-TV-turn-off-and-on-by-itself

Kindly do not keep attempting to turn it on, as you are likely to spoil some other boards/parts/components of the TV. Look for any loose contacts in power out let, RC jack, cable and socket. In order to ensure, it is not caused by the input device, connect a DVD player and see. Switch off TV, switch off power, remove plug and wait for 48 hours and retry. If problem persists, I suggest it is better to refer it to a qualified service technician, since the back cover has to be opened for investigation/rectification.
This is due to bad caps read here what a cap is www.badcaps.net see you tv is getting hot as normal but the caps cannot stand it any more thus shutting the tv down. The bad caps would be more or less in the power supply unit of this TV. So you can buy a new psu or get it repaired by a expert.
