FAULTY Brother M95 label printer | WON'T TURN ON | Can I fix it?

Описание: I picked up this cheap from eBay as a no power fault, won't switch on. It's a lovely little label printer, in very good condition. I think the negative polarity might have caught someone out and fried something inside. Watch the video and let me know what you think.
