Power on but it's has a creaked screen

Cyrese Smith a cracked screen is not fixable. It needs to be replaced. You would need to contact TCL to see if their warranty covers cracked screens. Most do not, but it does not hurt to ask.

If it is not covered under warranty you will have to find a new screen. That could be a challenge, depending on the model number for your TV. The larger the panel the harder it is to find and the more it costs. Most of the time, a new panel cost more than a new TV. So, let's wait and see what TCL says and then let us know.
