@sam1990sja “switching it back off and on again good few times” could be a power board issues. We do need to know the exact model of your TV. To possibly help you out further unplug your set and remove the back. Then take a good look at all the board check for obvious damage like leaky or domed capacitors etc. Post some pictures with your question so we can see what you see.
