Question about Kenwood VR-8060 6.1 Channels Receiver
Receiver functioned fine for almost 2 years and now is powering off immediately like it is in a protect mode and the led by the power button flashes. It sounds like it is going to power up and as soon as you hear the "click" for the output mute it powers down. I am unable to measure the output on the transistors because it powers down right away.

SOURCE: No sound from speakers
In most recivers or amps yes if there is a short in one channel all the amps go into shutdown or into the protect mode. Now if you know how an amp works then you should be able with a schematic to find out what amp is causing the over load simply by see in the schematic where the speaker output is on the curcuit and then measure for a DC B+ . Thats the amp you would disconnect to conferm that all the others were ok as an output on an amp curcuit shouldnt have more then .3 to .8 volts dc unless its unbalanced.. Seek a pro to assit you if you dont have the equipment to test the amp and for sure get a service manual or schematic diagram. Good Luck

if you sent 110v down the speaker wires & into the amp you most likely have damaged the audio outputs or the output ic. Look for a big aluminum heatsing & on one side you may find 1 or 2 ic's or numerous transistors, the ic's are hard to check, the transistors are easier to check, if transistors replace in pairs. also check for burnt /open resistors near outputs
