It turns on after a few seconds then tv turns off

This happened to me last night while I was playing and suddenly the tv just went off,

So I tried restarting it and it turned on for a few seconds and went off again so I tested if it was the tv that has a problem so I turned off my ps4 and watched some news but its just fine and then I turned on my ps4 and the tv turns off again

And just this morning i tried to turn it on again but my mom was watching tv and the tv suddenly the tv turned off and wont turn on now whenever i press the power button it makes the turning on sound and then wont turn on

I need help
