Default Acer Extensa 4630z - Power on then off

Hi all,

I have laptop acer extensa 4630z.. the problem is everytime it's turned on, stay on for couple seconds without any display then shut off.

I already remove everything except ram, mainboard, power board. I have tried connecting straight to the power adapter still have the same problems. Same problems still occur whether running on battery or through power adapter.

No heat at all on all of the components.

Anyone had any idea on this problem?
