Sounds like the inside plug port has shifted. On the lower end Brother machines, there really aren't any service panels to remove. There's a front cover and a back cover that are screwed together. You have to remove as many screws as you can find, then there are a couple that are hidden deep inside the machine. I think if you can just get the bottom of the machine to open a crack, you can probably shift the plug port back into position, without removing the covers. Avoid removing the covers if you possibly can. There are circuit boards inside that have delicate wire connectors that can break easily.
