Question about RCA F27615 27" TV
Hello Jjwpod hi, to find where the trouble is, you need to place ear near speakers, you should hear a humming sound, adjust the volume up or down, the humming sound also goes up or down, this means your amplifier is working, no hum means trouble in amplifier.
No hum: trouble in amplifier, speaker connection.
Humming, but no audio: problem before amplification, most likely the Sound IF stage.
