Kenwood Amp blinking Standby indicator light

Kenwood KRF-V8090D Amplifier is displaying the error message, which on page 58 of manual states, that the 'Cause' is that the 'Speaker cords are short-circuited' and the 'Remedy' is to 'eliminate the short-circuiting'.

I have disconnected all the speaker connections, the sub and even the FM antenna, but I am still getting the 'Standby indicator light blinking' when the unit is switched on.

I have also tried 'Resetting the Microcomputer' and plugging into another power point, but no luck.

Any suggestions?

    Hello I have a Kenwood VR-409 with the same problem. I disconnected everything, tried to reset, but every time I push the power button it breifly comes on than goes off and blinks. I also noted the the MUTE indicator light shows on the panel, I never use the mute and don't know how or why it is showing..

Hi fuxsiloh.

It sounds like you have eliminated all the things that could generate this symptom that are external to the amp. It is most likely that there is an internal problem that is causing the amp to go to protection mode. A power supply failure(maybe a fuse) is the only really user serviceable part inside the amp. Perhaps check for failed fuses, replacing any that may have blown with exactly the same type. BE SURE TO UNPLUG AT THE WALL FIRST:)

Is the amp still under warranty? If so, then returning it to a Kenwood service center is the shot. If you want to have a go at repairing it, I can talk you through it, but some experience with this sort of thing is very necessary. Good luck

regards
Graeme

Sounds ok but not dialogue...


It sounds to me like you are using the receiver in surround sound mode and the click you hear is the center channel turning off. If you have another center channel speaker, try swapping that for the one you are currently using. If that doesn't fix the issue, then try replacing the speaker wire. If that still doesn't fix it, then the issue is probably inside the receiver and may be either an output transistor that is failing when hot or an electrolytic capacitor that allows too much DC offset when hot.

Hi, my speakers are starting to sound a bit weird and i think its cause of pplaying around with the equalizers and settings on the Kenwood Amplifier, am just wondering if there is a reset button to restore...


Why guess? Get the manual out and actually look at the settings to see if they're out in space somewhere. If you don't try to understand what went wrong you will repeat it.

I have been using my Kenwood KRF-V7030D amplifier up until now without any problems... But now It simply wont turn on... There is power going to the unit as the red led lights up when the power cord is...


http://www.retrevo.com/support/Kenwood-KRF-V7030D-Receivers-manual/id/480ag204/t/2/


If it's microprocessor-related try the procedure at the top of page 26. Of course, this will clear all your custom settings...


"Unplug the power cord from the wall outlet, then plug it back in while holding down the POWER key."




Generally speaking, an amp protects itself from heat, shorts and overloads.


Overloads can be from excessive periods of high output and shorts would be wiring issues or a speaker blowing up.


You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.


If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.


If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced hands-on tech.

Hey,i have a problem with krf5100,when i do speaker custom setup,my RB and LB wont work,they even dont appear to display like L and R .whats the problem?


First of all, the KRF-V510 doesn't support direct powering of the Surround back but it does have a Pre Out to drive externally amplifed Surround back speaker(s).

The indicator for BS on the front panel is NOT an indication of speaker presence. It IS an indication of the INPUT presence of that channel.

During setup you will only see RB or LB ...

Page 17: IF you have something other than OFF set for Surrounds....
Page 17, step 9: AND you select something other than OFF if you have Surround back Speakers attached to the speaker connectors...

.. and complete the rest of the setup properly. You should HEAR the Test Tones on all speakers. If the Surround Back is inaudible you would need to investigate the external amp/speaker combination you're using.

In my display is says 3-03 when ever i plug in my rca cables and no sound comes out?


From Page 7 of your manual... this is indicating a grounded speaker wire (blown voicecoil).

It has shut down to prevent damage. Disconnect the speaker wires from the amplifier and power on the amplifier again. If the error persists - you will need to have the amplifier repaired.

Check the voicecoils for proper imedance.
