Question about Kenwood VR-409 Receiver

1 Answer

I have a Kenwood VR 409 receiver that mutes itself

I have a Kenwood VR 409 receiver I recently acquired from a neighbor. It silences itself about either 30 seconds or up to 3 minutes after it is turned on. I disconnected all speaker wires from the speaker jacks on the receiver to rule out any shorts, but problem remains. The previous owner denies having a problem with it.

I looked in side and can see four large capacitors that have the plastic wrapping (the black sleeves that has the printed values on it etc.) shrunk off the top and somewhat down the sides of the capacitors--I mention this because a friend once told me that when this happens, it means the capacitors need to be replaced. Is this true and could it be the culprit?

Hi JandS

Good thing that you noticed the capacitors, and your friend is correct. the capacitors at that state needs to be replaced because it has met its end of life. worst is that corrosion will start running down the circuit board possibly destroying more components.

have the caps replaced, this will not cost more than 5$ each. and if you have a soldering set or someone you know does, this is just a 5-minute do-it-yourself soldering.

hope this helps.

regards,

voodoo

I have a kenwood k-stat home receiver and it is stuck on mute. i dont have a remote with it and was wondering what button to push where it will get off mute.


hello, if you dont have the user manual you can get from this link
http://www.retrevo.com/support/Kenwood-VR-407-Receivers-manual/id/480ag200/t/2/
according to the manual i think you have turned of speakers, if so you can turn them on again.
as the users manual says it should be the 11th button group, you find this pair of buttons in the left side next to the power botton, you might have turned off speakers.

Kenwood VR-409 surround system clicks off when sound is turned up


Assuming you aren't turning the volume knob past half way before the problem occurs, you most likely have a damaged speaker cable or a bad driver in one of your loudspeakers. (Once your volume knob has reached about half way the amplifier is producing its maximum efficiency.)

Note the position of your volume control when the clipping occurs, then remove one speaker at a time and raise the volume. If you identify a speaker as the culprit, inspect or replace the wire running to it and try it again. If you aren't able to find a bad speaker, the problem is internal and will need to be fixed at a repair shop.

Good Luck,
BB

Kenwood receivers recently have a commonly known problem with its receiving IR diode within the receiver, to fix this you will have to re-solder the connection on the receiver panel within the faceplate of your kenwood receiver.

Instructions to fix it are at the following link if you are willing to open up your receiver and repair it. lots of people have reported this fix as successful so it is widely believed to be a design flaw in the VR line-up of receivers as it has occured in all the VR families so far.

good luck.

Kenwood VR-405


more info would be nice. If you're using optical, make sure its securely in both the tv and your vr-405 receiver. I have owned the vr-405 since 2000 and i just purchased a sony 32xbr6. HDMI into the TV, optical out to the receiver, it sounds amazing!
