Can you give us a history on the machine? Any impacts, repairs, liquid damage. Animals sleeping on the keyboard? Monsoon weather? Has it been opened and inspected? Corrosion evidence?

No corrosion evidence, the logic board looks very clean, and yes there was liquid damage but it was 4 months back the laptop worked for 3 months suddenly one day it shut down and didn't switch back on

I/O board has multiple functions:

  • MagSafe interface
  • USB port
  • Headphone jack
  • Microphone

The jack and mic connect to the Cirrus DAC chip (Marked in Red) Looking on the other side we can see the power lines from the MagSafe connector which connects to the main logic board.

Sadly, I suspect your main logic board has a problem.
