Question about Kenwood Audio & Video Receivers

1 Answer

My Kenwood vr-8070 suddenly will not work. When I push the power button, it simply blinks and I get no LED panel display, and no sound. I unplugged, and reset all the factory defaults as per the manual, still nothing. It sounds like a circuit breaker is being tripped but I can find no re-set and the manual is of no help. Can you help me? I sure hope so. Thx JRH

    Thanks for your quick reply. After two calls to Kenwood support, it has pretty well been determined that the problem, as you state, is internal. I unhooked all the speakers and its still dead.

    I found an un-authorized repair center, and I'll just have to take the unit there. I have no voltage meter, but I'm pretty sure its the transformer or amp. I have no idea how expensive it would be to repair, but I have a bad feeling. The thing is still under warranty, but I would have to mail the thing etc because there are no authorized service center anywhere near me, so thats not really an option.

    I do appreciate your help, and I hope it is something simple that is wrong. Not likely, but I can always hope.

    Thanks again!

    Jeff

It is going into the protect mode. Unplug all speakers and try again. If it turns on you have a bad speaker.

Plug in one speaker at a time turing the unit off in between each speaker and when it goes into protect again you know the last speaker plugged in is the bad one.

If the receiver still goes into protect with no speakers connected, you have an internal amplifier problem. This is something that should be checked by a service center. This particular model is not an easy one to disassemble and troubleshoot.

The sound you hear that sounds like a circuit breaker is actually a relay. It makes a clicking sound when turned on or off. That relay is functioning properly. It supplies the A/C voltage to the main power transformer.

Sometimes when the display is not lighting up at all and the unit is displaying all the symtoms your has, the power transformer is at fault. If you have a voltage meter or a ohm meter (multimeters have both) I can guide you thru the process of determaining if the transformer is good or not. That is an easy enough process for most people.

Let me know if you need more help, and a rating of "FixYa" would be appreciated if you found this information helpful.

    Here are the addresses for the Kenwood factory service, it would still be cheaper, and I mean much cheaper, to ship it to Kenwood and have it repaired under warranty. Kenwood will pay for the return shipping. You just need to get it to them.

    Shipping may only cost about $50 but the repair will cost close to $200 if the power transformer is bad. And $150 or more for a bad output channel.



    I work at an authorized Kenwood service center and assure you these are the correct addresses.



    Make sure you send it with a proof of purchase, and pack it properly and then insure it for the amount of purchase price.



    Call the closest place to you and make sure you don't need anything else. They may even reimburse you for shipping to them. Just ask.

Kenwood VR 605 power light flashes


CHECK FOR CLEARED COOLING VENTS & FOR PROPERLY WORKING COOLING FANS. THIS WILL CAUSE SHUTDOWN OF THE UNIT. IF ITS ALL CLEAR, YOU PROBABLY HAVE A POWER SUPPLY ISSUE.

Works fine, but led display suddenly stop working


This symptom is quite often seen when there are bad connection at the display itself. Generally on the front panel, the display will be a long part with multiple pins. The ones on either end are for the power and grouind. Try resoldering all of the pins on this part first. If that fails to resolve the problem, update this and we'll look further.

Receiver shuts off on its own


A very common issue with receivers turning themselves off derives from a power overload caused by shorting across the speaker wires. Check each wire to make sure there are no breaks and that the ends of the wires are cleanly separated (no errant strands accidentally touching between positive and negative) at both the receiver end and the speaker end. One easy way to test it is to just use different wires and see if it happens anymore. Another unlikely possibility is that the receiver may be set to a different resistance setting than your speakers (say, 4 ohm instead of 8 ohm)--though modern receivers tend to have internal ways of recognizing and dealing with that.

Receiver standby light,no power


WOOHOO!! I fixed this issue... same problem as everyone else has mentioned... to reset the Kenwood VR-606 receiver, unplug the unit. Hold the power button down and while holding the power button plug the unit in.
Say a prayer...
Then press the power button.
My display isn't working, but my speakers are working, and that's really all I care about right now... good luck to others!
