Re: on and off switch

This is the thermal overload for the amplifier section. unplug unit and check all speaker connections for a crossed wire. After all connections are checked and are in good condition, plug the amp back in and power up. Note: the polarity of the speakers when the wires are plugged in. Use the painted line on the speaker wire as a guide for which one is positive(+) and negative (-). If an amplifier is operated out of phase for too long ( positive and negative reversed), you can damage the amp. A bad speaker coil can cause the overload as well. If it still does it, disconnect all speakers and power it up. If these remedies do not solve it, you amplifier IC is shorted and needs replaced.

From the sysmptoms presented it seems that the main circuit board in your kenwood needs replacement . This happens sometimes due to extensive usage and power surge. I am unable to know your location. Hence sending the entire list of all contries contact number for Kenwood. Only they can replace the authentic main board.

Let us know if you want something more else accept the solution.
Thanks for contacting

My kenwood 107VR keeps turning off on its own, after about 3 secs it shuts off and the light blinks.

If you are sure your speakers are good. This unit has a protect circuit keeping the unit from turning on. This recevier uses an ic instead of output transistors. A ic incorperates transistors,resistors,capactors in one assembly for size and costs. There is a number right on the front of the ic ,you can go on-line to buy the ic is is fairly easy to put in as long as you can desolder and solder in.

Hooking up Kenwood AR-304 to LG TV

You need to connect the TV "Monitor Output" which will be standard audio (RCA) red and white. Then you need to make sure you go into the TV's main menu and go thru "Audio". You may need to turn off the TV's internal speakers to get output via the RCA monitor out. If by chance it has a setting for "Fixed or Variable" for the output, select "Fixed" and control the volume thru the receivers volume control. If you still need further help, don't hesistate to ask! I can walk you thru it. Hope this helps

Hook up for an AR 404 receiver

Copper is positive, aluminum is negative. OR One of the wires should have a white (or black) stripe on the insulation...this is negative wire. OR If using 18 gauge extention cord wire, the positive wire will have small grooves running the entire lenght (very difficult to identify, unless you have good eyesight) Hope this helps.

Turns on then shuts off like it has a bad fuse


Check to see that all the speakers are firmly connected at BOTH ends.
Also,if the receiver has speaker select switches, see if turning off the speakers allows it to stay on.

Let me know , Thanks

Starting system cold, no sound for 2-3 minutes

Its not worth having it looked at. $100.00 for a new 400.00 unit? My unit is doing the same thing. Turn it on and 2 to 5 minutes later it may come on. Change to video 3 4 5 etc it stop again. Only works with a cold start. Something in the unit has failed and is heat related. My original Kenwood 20/20 recevier still works. Must be 40 years old. New products just last 5 to ten years max if your lucky.
