Usually bad connection occur between coaxial cable and the the coax cable connectors. If that doesn't solve the problem, then there may be something wrong with your tuner card inside of your Sherwood receiver.
If you receivers display does not change channels or frequencies or AM or FM mode, when you try to change the channel or frequencies, or AM or FM mode, there may be something wrong with the front board of your receiver.
