Question about Kenwood VR-8060 6.1 Channels Receiver

Open Question

Powers on but immediately goes into protect and powers off

Receiver functioned fine for almost 2 years and now is powering off immediately like it is in a protect mode and the led by the power button flashes. It sounds like it is going to power up and as soon as you hear the "click" for the output mute it powers down. I am unable to measure the output on the transistors because it powers down right away.

SOURCE: No sound from speakers

In most recivers or amps yes if there is a short in one channel all the amps go into shutdown or into the protect mode. Now if you know how an amp works then you should be able with a schematic to find out what amp is causing the over load simply by see in the schematic where the speaker output is on the curcuit and then measure for a DC B+ . Thats the amp you would disconnect to conferm that all the others were ok as an output on an amp curcuit shouldnt have more then .3 to .8 volts dc unless its unbalanced.. Seek a pro to assit you if you dont have the equipment to test the amp and for sure get a service manual or schematic diagram. Good Luck

SOURCE: Kenwood KR V8080 receiver

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

Power problem


If the protect function works but is causing you problems, cancelling the protection function should help, and it will be possible to enter the self-diagnostic function mode. This should disable all functions of the protection mode, excluding the 'excess electrical current detection' feature.

While pressing the "Tone Control" and "Info" keys, try pressing the power key to turn on the power. Keep pressing those 2 keys for 3 seconds longer.

this should activate the Self Diagnostic function, with your Protection Mode disabled.

in this mode the 'sleep' section on the tv's fluorescent display flashes to indicate that the mode is properly activated.

just be very aware, this function is normally there as a safety feature and i cant guarantee that disabling it altogether won't cause other problems down the road. best of luck!

Receiver keeps going to standby


I don't know about the newer receivers but this sounds like an arching OFF/ON power switch that was a problem on Pioneer receivers years ago. I would bypass the switch and see what happens.

1. Unplug unit from wall.
2. Jumper two wires going to off/on switch using alligator clip with insulated boots on clips.
3. Plug amplifier into disconnected circuit breaker/fuse protected AC strip.
4. Plug AC strip into wall outlet, turn AC strip switch ON and see if problem disappears.

When power button turned on, receiver powers up


I have had the same problem with my new Onkyo HT-S 5305B (A/V Receiver + 5.1 speakers). To solve this, try to follow "Troubleshooting" guide that came with your system. I followed it 2-3 times. In my final attempt, when system was not shutting down but stayed-n with no sound, I played with the setup and tried changing audio adjustment, input, dimension etc. and slowly I was able to get speakers up one after the other. It's working fine now.
However, I am little concerned that why such a high-class Onkyo system failed in less than two days, forcing me to troubleshoot. - Apurva

CROWN CE1000- slips into fault immediately after connection


if ur output power amp is defective u will have that problem - meaning the moment u connect load across it it will go into circuit protection to limit/stop excessive output current. make sure the speaker terminals are connected to +/- output terminals. in bridge mode use only channel 1 and that too with 4 ohms speaker only otherwise amp will clip. considering all connections are okay if it still clips when speaker is connected, u have a faulty power amp section. this the way ur amp is designed

On power on it immediately powers back off.


THE GOAL HEAR IS TO DETERMINE IF THE INSTALLATION IS CAUSING YOUR PROTECTION FAULT OR IS IT THE RECEIVER ITSELF HAVING INTERNAL DAMAGE. REMOVE THE RCA INPUTS AND DISCONNECT THE SPEAKERS, THEN POWER THE AMPLIFIER UP WITH THIS NO INPUT, NO SPEAKER LOAD CONDITION. IF IT STILL GOES INTO PROTECTION (POWERS OFF), THEN THE RECEIVER WILL NEED TO BE SERVICED, AS YOU HAVE TOTALLY SIMULATED A BENCHED CONDITION THAT IS TOTALLY INDEPENDENT OF YOUR INSTALLATION. MOST TIMES, THE RECEIVE WILL GO INTO PROTECTION WHEN IT SEES AN EXCESSIVE LOAD WHEN TURNING UP THE VOLUME, WHICH IS USUALLY CAUSED BY TOO MANY SPEAKERS OR DAMAGED SPEAKERS, BUT IF NO SPEAKERS CONNECTED, THEN IT IS USUALLY BECAUSE THE RECEIVER SEES AN EXCESSIVE LOAD DUE TO ITS OUTPUT SECTION BEING DAMAGED. IN ANY CASE, ONCE REPAIRED, YOU MUST CHECK YOUR SPEAKERS FOR BURNED VOICE-COILS, WHICH WILL IMPOSE AN EXCESSIVE LOAD TO THE AMPLIFIER AND CAN CAUSE IT TO FAIL AGAIN. LET ME KNOW IF YOU NEED FURTHER ASSISTANCE.....V

"protected"


First, disconnect all speaker wires from the unit and power it back up. If it does not go into protect. post a comment and I can walk you thru troubleshooting. If it goes into protect, it needs to be serviced.

The dvr99 3 dvd home theater receiver will not stay on


Protect kicks on commonly when it over heats or when the speaker wires are crossed and it detects a short on the output. Your symptom sounds as though it may be a speaker wire because it happens right after the power is turned on. Check the speaker wire carefully, it has a habit of breaking inside the connectors of both the receiver and the speakers, especially after 5 years of service.

Denon AVR-1100 receiver "PROTECT" mode


replace all the electrolytic capacitors in the power supply. i had the exact same problem with mine and once i replaced the capacitors it powered up and stayed on and worked perfect.
these capacitors tend to fail as they're of poor quality.
this fault is very common on denon receivers, especially the later models.

hope this helps?

The receiver has gone into a protect mode because something is wrong and it shuts down to prevent further damage. Could be a power supply or output amp issue.

Immediate shut


Unplug all the speaker wires first, then unplug the unit from the wall for at least 24 hours, The plug back in without the speaker wires or anything else plugged in. Then see if it goes to the protection mode. If it does not, plug in each speaker at a time, and see if any speaker, when hooked up, makes the receiver shut down. If it does shut down, My friend, I'm afraid you will need to take this unit into a repair shop, OR get a new unit. Good Luck
