Well it keeps shutting itself off. Simple as that. My sleep timer is not on. Nothing is set on it, it simply just shuts off on its own. It will be on for random periods of time, some long some short but sooner or later click!. VERY frustrating can anyone tell me what is going on and how it can be fixed!?

If you don't hit a remote button for a few hours, the TV turns itself off. Check to see if there's a settings option to disable this power saving feature, or to extend the time before it automatically turns the TV off. Maybe a sleep timer setting? The sleep timer is off. Tv keeps shutting off Google Search
Check the tv menu settings...go to where you set the date and time etc... usually in the general section..
Look for timer or timers...turn off sleep timer, turn off power on timer and turn off power off timer...cheers
When you press the Power/Sleep button the radio turns on and displays a
number 90, or some other numbers. This is the play time that the radio
will stay on then turns itself off. It could be that yours is configured
with a sleep timer set to 01 minute, 10 or 15. You need to set the
timer for a longer period. Thus we turn it on by pressing the
Power/Sleep button, read the timer length then press again. Keep making
short presses: The timer will cycle through all preset sleep timer
durations. Select the length you want.
Put your hand on the back of your TV to check for overheating, if your set keeps switching itself off without warning.
Many TV sets come equipped with a safety feature that switches the power off if the set gets too warm.
Check the cooling vents located at the rear of your unit. Vents can collect dust and dirt, resulting in the fans becoming blocked and failing to work properly.
Remove dirt from the vents with a damp, clean cloth. Ensure the air conditioning is kept at adequate levels in the room where your TV is located. Keep the drapes shut on hot, sunny days to keep the room cooler.
Check the sleep-timer function on your TV if it keeps turning off. A sleep-timer is used to turn a television set off after a certain period of time has elapsed. If the sleep-timer is not turned off, your television will continue to turn itself off after a certain period of time.
If the problem persists,then a heat sink has gone bad.
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.
Take a can of compressed air, open the back and clean the dust off the circuit boards.
