It appears you had a high voltage arc between the display can and the power supply. I think if you clean the area I marked with a bit of isopropyl alcohol you’ll see the trace is damaged.

So the power supply is damaged!
But being a high voltage spike (likely lightning or a crossed wire on the power lines from a tree fall) there maybe more damage than just the power supply.
At this point you’ll need to give a new PS a try [product|IF173-046]
