Could be overheated capacitor or a faulty power inverter. You can get an analog tester or ohmmeter and test the capacitors. And you can use a voltmeter to check the power inverter.

firstly, check your TV settings and to confirm if the timer is on or not. The timer might be the reason your TV turns off frequently.
If the timer is not on, then the timer is not the cause of the problem.
There are two reasons why your TV keeps turning off, 1) could be the on/off button. The button my be popping of at interval, that is, it may have worn out and not hooking well. 2) could be over heating. The heat sink maybe dusty.
Either way, the solution is quite simple. The on/off button simply toggles a low voltage circuit that powers your TV. If it is dusty, it may complete the electrical circuit and send a false signal.
A heat sink may be dusty and unable to dissipate heat. Over temp protection may be switching the TV off.
Allow the TV cool, open the TV back cover and clean the dust off the circuit boards. You can use a paint brush to remove the dust from the TV board.
