Out LG 55 inch 4k TV SJ800T restart abruptly while watching content on it.

There is no pattern in restart, sometimes it restart once or twice or more in row.

Sometimes it does not restart for month.

Since it's very random, hard to record it's video or try out something and confirm problem is fixed.

I have tried resetting TV, updating it to latest firmware. but no go.

If any one have faced similar issue, let me know it's solution.

LG service is charging 1400/- just to visit my parents home. since it's 60 KM from city.
So currently we have not availed LG service.
 
Disconnect tv from internet and check. But since it might not happen for another month , difficult for you to connect and disconnect everytime you switch the tv on for a month.
Do you have a smart device like a Google home connected to the tv ? If yes. Disconnect.
Also the lg app on phone has the facility to start the tv . Remove that app.

Only device connected to TV is d2h set-top box.
TV is not connected to WiFi.
 
Thanks, Will try out disabling Quick Start and HDMI CEC.
Try them but its unlikely to be these two options.
There are some simpler things such as a loose power cable at the TV and socket end. Some TV's have a detachable power chord.
Its also possible your parents accidently flipped the ON/Off timer.
That document covers a number of things right to clearing of the cache.
Go step by step.
Once you have checked everything, then you can call LG and have them attend to it.
If its happening once a month, you might as well just live with it.
