@omputers

going by your description alone my number one suspect would be the power board. Let us know if your TV shuts completely off or if it just the screen that turns black. Also, try multiple different input sources (one at a time)and see if it still shuts off. Something like a bad cable box etc. can cause this as well. Remove the back from your TV and check all the boards. Check for damaged looking components etc. Post some images of your boards with your question so that we can see what you see. Adding images to an existing question

all components look fine and its something that happens randomly sometimes runs for hours no problem than it will happen, other times it will do it within 20 minutes looks like if i was to turn off and on but i did not do anything,I reset the settings its a smart tv so i use the smarthub to watch netflix to see if its the box were hdmi connects to but that is not the issue

Have you checked to make sure the power cable is fully plugged in sometimes the cable can be slightly unplugged and work for a period of time than shut off.

Check the connection very well. If the power ups and down then this might happen.
