How to remove this grub screw/pin to remove door hinge?

[Laubi]

Hi all,

Door hasn't been closing properly only to discover the door is sagging a little as the screw has come loose at the top bracket/hinge. I can't access the screw due to the hinge. Problem is the grub was old and rusted. I cleaned it, tried Allen key, then used a screw extraction with no luck. Even tried tapping the **** out of it from below.

Is there any other methods I can try please? I figure I just need to remove the pin/hinge and the. I can screw in the bracket to the door so it's flush to stop it sagging.

Many thanks

Use something to punch pin out from the bottom.
Just a tap. See if it moves
