When I last checked, there were 3 repair services precisely for this issue at eBay.com, doing the fix for around $40 shipped (do a search on Dell Venue 8 Pro repair). One service, MYdeviceRepair, also will put in a micro-B socket rather than the current micro-A socket, if one would like.
The socket itself can be found on eBay.com for less than $10. I also saw that open-box or manf. refurb. DV8Ps can be found on eBay.com for an amazing $150 or so.
