No sound from front left channel
Hi, here is a procedure to discover the source of the problem. No sound from the left front channel can have several sources other than the left front channel itself.
Let's assume, for just now, that the speaker is good and the cable to it is good.
Here is a testing sequence to follow:
1 If you have a CD player connected to it. Put a CD in and put it into play mode.
2 reverse the connectors from the CD player to the receiver. See if the sound moves to the left speaker and stops on the right speaker. Or if it plays fine.
3 If the sound reverses channels, That cable is bad. Replace it
4 If the sound is still not coming from the left channel. Check the connections and cables to the speaker. MAKE SURE THERE ARE NO STRANDS OF WIRE TOUCHING THE CHASSIS OR SHORTING TO THE OTHER SPEAKER WIRE.
5 If there were. Correct it. Shut down the receiver and then after a few minutes turn it back on.
6 If it still does not work. check to see if a tiny amount of sound is coming from the left speaker.
If so, turn the music up and see if it pops back on . If that is the case there is a failed resister on the circuit board that is arcing when you turn up the volume. That being the case, it is time to drop off the receiver to be repaired in the service center.
Hope this helps,
