M3 MacBook Air Won't Turn On

I bought a macbook air m3 in June 2024. After about 5 months, the computer started to show some problems. Sometimes it would start up instantly, sometimes it would start up in 40-50 minutes. I did a disk check and everything seemed normal. There was no problem when the computer started up. I also get technical support. I delivered the computer and they detected that there was liquid issue. They changed some parts of my computer. After these, I received the computer and saw that the problem still have. I just don't know what to do. The computer responds when the power button is pressed, the power-on sound and the Apple logo appear, but then it just goes black. Sometimes it starts up instantly. I was format this computer but issue still have. What can I do?
