Check for shorted speaker wires on left channel. If not, disconnect speaker wires and check to see if headphone jack works. If left works, you may have a blown speaker. If left still doesn't work, left power amp blown.

an amp of this size generates alot of heat internally when in use as these use mosfet ICs and can get very hot.
your problem is most definately dry solder joints and possibly quite a few at that.
i've repaired quite a few sony surround receivers with similar problems and have all been down to dry solder joints.
hope this helps.

when you amplifier is powered on if the speakers are powered on and you hear that the output is switch on then it is possible that the fault of the amplifier is in the preamplifier.Open the set and check on the input of the amplifier with a signal . If there is output the fact is confirmed of the preamp stage. Now we have to confirm if the fault is in the source swtiching or the preamp equaliser/ tone section. Using a good signal tester and hoping that you are familiar to handle the electronics inside, the IC can be identified and changed. Use extreme care and test at low output, Use a help of an expert to signal trace the fault. Hope I could help. Good day

I'm sorry to know that the left channel of the amplifier is not working as expected. I'll be glad to assist you with this. Please try the following steps to get the issue resolved.
If you are not able to get any sound when playing audio from one of the speaker, there may be a problem with your hookup or there may be an incorrect setting. Follow these steps to try to resolve this issue:
Try selecting a different sound mode on the A/V receiver, such as the Dolby Pro Logic II (DPLII).
A majority of cable and satellite TV channels are broadcast using two-channel analog audio. When watching one of these TV channels, only the front speakers will output audio. In order to hear audio from all speakers, make sure to change the sound field to DPLII. This creates a simulation of 5.1 digital audio. If the channel is broadcast in digital 5.1 audio, change the sound field back to AFD Auto to enjoy the digital surround sound audio as it was actually recorded.
If you still have the same problem after changing the sound mode, make sure the speakers are securely and properly connected to the A/V stereo receiver.
If your A/V receiver has an Auto Calibration function, try using it to setup the appropriate sound settings.
Perform a Test Tone operation to verify that all speakers are working.
Increase the volume level of the speakers.
If applicable, try selecting a different size (small or large) speaker.
Try these settings which should resolve the issue. Please feel free to get back to us for further assistance.
Thank you for using FixYa.
