Question about Audio & Video Receivers
If the speakers themselves work fine, then the problem lies within the amplifier output. The channels can go bad after hard use, they can be repaired but it may well exceed the cost of the amp if it is not just one channel. Also be sure that you are hooking up speakers that are rated for your amplifier by matching the OHM resistance of the amplifier to compatible speakers.

The f-l channel of the sr18, & sr18ex & sr19 is a common failure location due to the heating and cooling over the years. The crackling an/or distortion, is most commonly due to the amplifier going into a high idle, or d.c. offset that can no longer be controlled by the adjustment potentiometers on the board. usually the two 2sc3200 transistors become unstable, and as well a 47mfd and a 470 mfd elect. caps nearby. Also distortion is caused by one or more of the zener and germanium diodes all grouped near the big dual ceramic white resistor. The amp block is held in by six screws. first remove the cross bracket, then cut the cable tie free from the hole on the board. Ten screws hold the top board on, the pull the boards apart from the connectors. before replacing it, resolder ALL of the connector pins to BOTH boards.

SOURCE: Speaker Detect error Left Rear
I had the same problem until i figured out that if u dont have surround speakers connected it will be a error when trying to configure the rear surround speakers.
So if u are running a 5.1 system and have hooked up ur surround speakers to the back surround speaker port u have to change them to the surround speaker port.
Hope this work for u
