My board will not run, I feel the wires are loose, how can I fix this?

My boosted board power was intermittent before i wiggled the back motor wires then it worked again. I feel that maybe the wires maybe got seperated from the circut board underneath the back cover. Has anyone fixed this issue before. BB will not fix my V1 board anymore so rigjt now it is a $1200.00 paper weight. Any help in this matter would be greatly appreciated. I miss my BBV1 sooooooo much. Thank you in advanced!!!!
