Power cord will be included its just not shown in the pictures. Sense the front was already off i opened it for the pictures to see if there's any obvious damage inside the only thing i see thats suspect is that L3 cap only because the shrink wrap is kinda raised on the end makes me think it got warm but im no repair guy so cant say with any certainty.
