Diagnosis: FM Doesn't Work

The tuner cannot receive FM stations or receives them poorly.

Safe first checks

  1. Confirm an FM antenna is connected to the correct terminals.
  2. Try a known working antenna or a different location.
  3. Check whether AM works; that helps separate an antenna problem from a broader tuner fault.
  4. Do not adjust tuner coils or alignment trimmers without the proper equipment and service manual.

Next step

Record whether the signal meter moves and whether stereo reception ever appears.
