Question about Kenwood KR-V8080 Receiver

1 Answer

Kenwood KR V8080 receiver

My receiver quit working when one of the speaker wire tips brushed across one of the receiver's power cord prongs while it ( the receiver)was plugged into the 110v outlet. This happened when I was messing around with the cords and cables behind my entertainment center, and the power cord was not pushed in all of the way. Since that time, the "Main Power" on/off switch powers up okay and the power light is on, however when I push in the "Remote Power" button the unit turns on for 1 second and then shuts down. After this the "Main Power" light flashes on and off. There os also a click simultanious to the unit shutting off that is coming from a small blue plastic box that is near the fuse in the back of the unit. Can you give advise as to what is wrong? The fuse appears to be okay.

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

How can i repair amp

Looks like the amplifier output transistors have blown (hence the pop). Quite expensive too repair - I would have a look on eBay for a cheap used but working Kenwood receiver, it would probably work out cheaper.

I have a Kenwood kr-v8010 and all a suddenly one channel is only working just woundering if its a easy fix?

Could be a speaker wiring issue, defective speaker or possibly a speaker protection fuse inside the unit has blown.

1. Check speaker wires for proper connection.
2. Swap left and right speakers to see if the problem follows the speaker.
3. Check for internal speaker fuse that may have blown. PLEASE proceed with caution inside the unit. With the AC cord unplugged there are still high voltages resident inside...BE CAREFUL!!

I have a kenwood KR-V8080 and i had 4 subwoofers hooked up to it. then one day it jus shut off an smoked a little. now when i turn it on an try an hook up speakers it sparks an the speaker pops. i dont kno...

You blew the amp. If you were running 4 subwoofers off of a dual channel amp you most likely running them bridged off of two different outputs. You most likely blew the resistor and because it was pushing more power then it could handle. Also when you bridge speakers it brings down the impedance which allows for the more power to course through. Suggestion is to buy a new amp that can handle 4 subs or 2 different amps for both sets.

Hi, My friend (who has a visual impairment) moved house recently, they own a Kenwood KR - V5570, I assisted with re setting up PC etc. I am now baffled with connecting her left and right speakers to this...

If you keep guessing you may succeed in blowing something up.

The cables have RCA connectors or bare wires for a reason.

Get the manual out and read it.

Don't pay too much attention to the actual colors of speaker wire. Use the colors as reference. Each speaker has a plus and a minus. Connect them to corresponding plus and minus for their respective amplifier outputs.

Familiarize yourself with the controls. Understand every indicator on the front. There may be a clue there. Turn the volume to a medium or low level before changing any settings or you may be in for a BIG (and costly) surprise when you find the one that was in the wrong position.

I have a Kenwood KR-A4010 Am/Fm Stereo Receiver. Every five seconds the sound fades in and out. Can anyone find a solution to this problem?

Something in the unit is smoked and potentially dangerous. Get that puppy down to a repair shop. Don't leave it unattended if you turn it on. Got a fire extinguisher handy?
