The system is sensing a screen failure. Will the system run a screen diagnostic (hold the D key through powerup)?

@ejn63 it still didn't turn on after the screen check (I did hold the d key and screen did flash colours but after releasing it laptop turn off and same error repeat)

Sounds like the display is OK, meaning the mainboard is the problem.

Unlikely, but no harm trying.
