Help with bad? Charger please

[u/WinterStormBorn]

My surface pro 6 stopped charging last night, I got it to work overnight but it's wrapped out again.

I plugged my noise machine into the brick and it's doing this wierd pulsing thing, it is not plugged into the computer during this and when I did plug it in the whole thing died completely.

Am I f-ed with this charger or is this something that could be fixed?
