Why do the TUNED and STEREO indicators flicker on my Onkyo Receiver?

If the TUNED and STEREO indicators are lit but the sound is distorted and stereo separation is poor on your Onkyo Receiver, the station signal may be too strong, or there could be multiple reflections of radio waves due to tall buildings or mountains. Try changing to a T-shaped antenna or use an antenna with better directivity, selecting a point where the distortion is least.
