Then the Phone was ok for few days and today bim!! The problem is hère again, i changed the tristar again😡 and the Phone is working now so my question is what can damage this tristar ic?

Yes it should be a cap or resistor.
The resistor will send the wrong voltage and the bad cap no voltage at all or a surge.

You'll need to spend some time testing every line that goes into the tristar, bet is getting hot until it fails.
