Hi,

LD2 is 5V presence, so, if blinking, it is likely the current limitation inside your USB Type-C supply (I assume blinking rate is very slow).

Did you try another USB Type-C supply/cable ?

@PatrickF​ Thanks for the reply, Yes I did try another C type USB as well as the USB PD adapter. But same response.

Is there any IC that I have blown up and which could be causing this?

Please advice.

I have access to lab where I have soldering accessories.

Could be any of a number of parts.

Could you have causes an ESD event when you fiddled with the switches?

Placed the board on a conductive surface?

Pull a schematic and start double checking supply rails, etc.

What if you remove the SD card?
