Question about Audio & Video Receivers
Open up the case and you'll see if the fan is working. Or you may be able to tell even with the case on. However, AVR's usually do not use fans.
Here are a few tests to see what may be going on: First check to see if the speaker wires are frayed or shorted. Perhaps they are touching near the speakers or AVR. Replace the wires to be sure. Then test the AVR by using a different set of speakers, preferably ones that are higher efficiency. That means they need less power to drive them. You can tell because high-efficiency speakers will not be sealed tightly and have ports or air holes in the case. Your sansui's are probably low efficiency ones (which sond better,) but need more power to drive them.
If the wires are not the problem and the higher-efficiency speakers do not help, try temporarily using a computer type fan on top or on back of the AVR to see if it works with the fan.
If it is not overheating, you probably have a bad output transistor or faulty power supply on the AVR.
Hope this helps :)
