Hello Khadas Team & @lilysun
We purchased a Khadas Vim3 in September 2019 but not until May 2020 we had the opportunity to try it. Since last year we have been evaluating various SBC platform, from raspberry, minipc, jetson and finally to khadas for our research that leads to production.
Unfortunately we found our Vim3 is defective as the HDMI port is not working. We have tried multiple HDMI cables and monitors that are working well but the device does not show anything on the monitor.
We also experience sudden freeze/lost in SSH connection repeatedly while the device is running. No problem with power and ethernet cables.
With all these problems, how we can get replacement unit under warranty? Or should we send back the device for diagnosis?
Thank you fro your attention.
