The charred connector is from the connector being loose for quite a while. It has nothing to do with daylight savings time or power strips
The wire needs to be replaced. You would need to lookup the correct Samsung part.
It's possible the board it connects to will also need to be replaced unless the terminal can be cleaned up enough to be shiny and bright. It's hard to tell from the picture.
Also, unless you actually know what you're doing in there, I would suggest that you put the cover back on and take it somewhere to be fixed, or throw it out and buy a new one. It's entirely possible for it to kill you even if it's unplugged.
