JBL xtreme power connection help?

[robert.keller.94]

My jbl xtreme power connection as seen in the pictures has came undone. I can push it back into it slot and occasionally it will get a connection and turn on. It doesn't seem to keep connection. So my question is how would I go about fixing this? Could I fix this myself with little electronic repair knowledge and how? Would it be easier to just take it to a repair shop?
