Hp g62-460st daax1jmb8c0 rev:c shutdown after a second problem

[ahmetozay]

Hi, HP G62-460ST DAAX1JMB8C0 REV:C is power on but shutting down after a second. i flashed EC and MAIN but the problem is same. When i check with the debug card it is shutting down when it checks CPU. I dont have the schema. Any advice is welcome. Thanks

PS: it has i3 processor which is onboard so its not removable

checked all on motherboard no short circuit. when i bend the board it works so there is a crack or cold joint on the board. still working on it
