Firstly, if there is a more relevant section for this question, i apologize ... (please move if needed)

So the owner said it had drink damage on one side, i have swapped over the complete jog assemblies and the issue still persists on the same side, indicating it's an issue with the board (DWX3614)
When i had the board out there was virtually no evidence of drink damage, i will investigate again, just thought i would do a post about it before i do.

So to clarify the problem, when in vinyl mode, stopping the jog from the top, the track holds fine, but moving forward or back doesn't move the track.
