If you can obtain an ohm meter, check the speakers by touching the leads to the meter and see what it says. The meter should be set to measure < 1 kohm. If it shows lower than 4 ohms you have a bad speaker. If you have multiple speakers on one channel then it cannot handle the drop in resistance and it is overheating.
My receiver model is Pioneer XV DV787. it was working perfectly for more then seven years, just there was SUB COM message blinking continuously otherwise everything was functional and perfect.Just to solve the blinking "SUB COM."massage, I applied the mentioned reset method.After that I am experiencing exactly the same problem.Nothing is working except power on/off and blinking same old message "SUB COM"
It means the amplifier is in the protected mode and has shut down to provent further damage. This is going to require a service tech. While it might be reselt, I think it would just fail again until a repair is made. This is a Pioneer brand and you can check to see what they offer and if it is practical. I found a service manula online for a VSX-D409 but it lacks troubleshooting info and primarily offers a blowup of parts and replacement parts list. This does not look like something for a DIY job. The user manual would say that if the unit is shut down and the MCACC light is blinking for you to contact Pioneer for a service.
How do I reset my Pioneer VSX 932?
