Ok here some images of the caps, back of board and front of board. The
cap wont pull out but then it may have welded when it exploded.

Do you have access to a DMM? If it has a diode test range on it it
might be interesting (and as I believe has been mentioned elsewhere)
to measure the 4 diodes to see if one (or more) are short circuit?

I recently repaired a multi-port battery charger that had two dead
diodes around the same area and similar on a PSU board for a big LCD
TV.

You might need to lift one end of any diode that appears to be short
circuit in case it's other components showing up as a short.
