No Sound Coming Out Of The Main Speaker.

I have a RCA RP7887A. The main (large) speaker is not producing sound. When it first occurred I just turned it off and on until the sound worked, but now sound only comes out of the small speaker. Any ideas on how to fix the radio?

There are a few things you can check to try to fix the main speaker on your RCA RP7887A radio:

Check the speaker wires: Make sure that the speaker wires are properly connected to the radio and to the speaker itself. You can try disconnecting and reconnecting the wires to see if that resolves the issue.

Check the speaker cones: Inspect the speaker cones for any damage. If the cones are torn or damaged, the speaker will not be able to produce sound. You will need to replace the speaker if the cones are damaged.

Check the speaker voice coil: The speaker voice coil is a thin wire that is wound around the speaker cone. If the voice coil is broken, the speaker will not be able to produce sound. You will need to replace the speaker if the voice coil is broken.

Check the speaker crossover: The speaker crossover is a circuit that divides the audio signal into different frequency ranges and sends each frequency range to the appropriate speaker driver. If the crossover is damaged, it may cause one or more of the speaker drivers to not produce sound. You will need to replace the crossover if it is damaged.

Check the radio's amplifier: The radio's amplifier is responsible for powering the speakers. If the amplifier is damaged, it may cause one or more of the speakers to not produce sound. You will need to repair or replace the amplifier if it is damaged.

If you have checked all of the above and the speaker is still not producing sound, you may need to take the radio to a qualified repair technician for further diagnosis and repair.

Here are some additional tips for troubleshooting the main speaker on your RCA RP7887A radio:

Try connecting the speaker to a different audio source, such as a smartphone or MP3 player, to see if the speaker produces sound from that source. If the speaker does produce sound from a different source, then the problem is most likely with the radio.

Try connecting a different speaker to the radio to see if the radio is able to power the different speaker. If the radio is able to power the different speaker, then the problem is most likely with the main speaker.

If you are comfortable with electronics, you can try using a multimeter to test the speaker wires, speaker cones, speaker voice coil, and speaker crossover. This will help you to identify the specific component that is causing the problem.

I hope this information is helpful.
