Vita won't turn on PS button is blue Already swapped battery,no luck

Charged the battery fully, during charge it was just solid orange When pressing the power button (to turn it on), the PS button turns solid blue, but no sound or no screen, when pressing it again as if you would power it off, it blinks blue like 4 times blue and goes off.

Already tried holding power button for 30 seconds, and it still stays black. Also tried R button plus ps button plus power button, nothing shows up. There is also no audio. Got this vita second hand, and was probably not used for a while.

Swapped the battery with one from another vita that works fine Still same issue. At this point. What could be the issue?
