dso nano v2 problem

hi there …

i’ve been playing around with my nano v2, and i seem to have a problem with the input jack. i think there must be a bad joint or something, as it presents an impedance of about 2ohms from time to time. a gentle wiggle seems to sort it out.

will opening it up to investigate harm any chances of return?

also, would be v willing to help improve the interface (that is what i do for a living) but implementing
changes may be difficult for me. is there someone out there who could help?
