Plug in for power cord is bad

Steven Grotte , I to, did a search for a while with out success on finding a replacement mother board for the RCA 10 Viking Pro, a lot of replacement screens and chargers, but that was it. What you could check into, is if the port is loose, is to possibly resolder it or replace it instead of the whole board( google search for Mini USB charge port to match existing one). Below is a link to see how charge port replaced. If not comfortable doing repair, maybe take device into a good local computer/cell phone repair shop, have them take a look, diagnose and estimate repair. Good luck.

I hope this helped you out, if so let me know by pressing the helpful button.
