Our products have passed the QC test before they are shipped, and we make sure they could work normally. Please test the plug via an electron probe. Check and confirm if there is power going through, or please connect them to the power directly. If they still don't work, please contact us and we could resend the replacement.
If you have any questions, please feel free to contact us.
