I planned to do some testing of my top of the line Zhiwhis ZWS-C919 and discovered that FM didn’t work. I tried the usual reset steps to no avail. Other bands worked, but FM was dead silent. I bought the radio in October of 2015, so it is still under the 12 month manufacturer warranty.
Around noon today, February 27, 2026, I sent Zhiwhis an email:
Subject: Warranty Support
I purchased your ZWS-C919 through Amazon.com on October 6, 2025 (Order *************) and have used it occasionally. Today I found that the FM band is no longer working; when the FM band is selected there is no sound at all. AM, SW, Weather and CB have sound, but not FM. Here is what I tried:
- Tried other bands: worked OK
- Verified that the Volume control was set to 30 (and was not flashing)
- Tried the RESET under the power-off options
- Removed the batteries from the radio for 1 minute and reinstalled
- Tried multiple strong FM stations
If the radio is on the FM band when I turn it on, then signal strength graph is shown on the display but no sound. If I switch to another band and then back FM, there are SNR values shown, but the graph does not move.
Please indicate whether this can be remedied by the user, or provide a replacement.
Note: When the volume is flashing, the radio is muted.
I think the Chinese New Year celebrations are over. I’ll update when something happens.
