Re: Ppower on then standby problem Kenwood KR-V8060

This fault may be similar to a Harmon Kardon AVR1550 fault I recently encountered. I did all the usual checks e.g. testing for presence of DC on speaker outputs etc. but all seemed fine, then the fault cleared! Next day it re-appeared and attention was (falsely) given to the protection circuits as the amplifier circuits themselves were considered to be in order. The HK uses both voltage and current protection circuits and it was discovered that the current protection circuit was operating. Eventually the fault was found to be one of the 0.39 Ohm 3W metal oxide resistors that had gone high in value on the left hand channel. Of course your amplifiers fault may not be due to this but the reason for going into standby would probably be the same i.e. due to amplifier protection circuits operating. You need to check out all the output devices and those resistors on every channel, even surround ones you may not be using. Hope this helps.

How to troubleshoot a kenwood kr 5600

These older tuner/amps have protection relays that when latching, are distinctly audible. Does the relay engage after approx. 10 seconds after turn-on? If not, check your speaker wires and/or speakers for issues. With all speakers (and wires) disconnected, the relay should still latch after turn-on. If not then you have an internal problem...likely a older pre-drive transistor that's bias is incorrect, which in turn causes bigger problems downstream.

Avr kenwood kr v5090

Have you tried the "Simulated" surround setting?

If you don't get sound in "Simulated" mode then you have probably lost the surround channels.

If you do get sound then your "Media"
is not recorded with a surround "Track". or the surround "Processor" may have issues that need to go to the repair shop.

Hi, try powering up the unit with out any speaker connected if it still goes to PROTECT try factory reset if possible.
To reset the AV receiver to its factory defaults, turn it on and, while holding down VCR/DVR, press ON/STANDBY. "Clear" will appear on the display and the AV receiver will enter standby mode.
If this does not fix your problem you should take your unit to service . :)

Kenwood amplifier KA127 the sound stopped and if I switch on/off it says ''muting'' what is that and where can I unmute? No matter what I hit nothing happens.

disconnect the unit from all inputs and outputs. Just you,the unit and the power cord to the unit. No CDs, no speakers, nuthin'!

Turn it on. if it displays the same message, Find Kenwood's service center.
If it operates normally, you had/have a short in the speaker system.

Lexicon RV-8 wakupe failure

Did you try this....

In the event of a power outage, the RV-8 will display a BROWN
OUT!! PRESS STANDBY message. To turn the unit on, use the
STANDBY button. For more information, see “POWER
MANAGEMENT” on page 3-3....


"Setup" >> "Power Management"

Opens the POWER MANAGEMENT menu, which is used to automatically
put the RV-8 into standby mode during brownouts.
When set to ON, the RV-8 detects low voltage levels or a momentary
loss of power and puts the device in standby mode. In the event of a
power brown out, the RV-8 will display a BROWN OUT!! PRESS
STANDBY message. To turn the unit back on, use the front panel
STANDYBY button.

When set to OFF, the RV-8 will attempt to function during a
momentary power loss, however software settings may become
corrupt and need to be reset.
When the RV-8 is in standby mode, pressing the button turns the
unit on and activates all zones that were active in the previous
operating session.

The RV-8 does not power on.
1. Make sure the rear-panel power switch is set to the | (“on”)
2. Attempt to power on the RV-8 with the front-panel Standby
button and remote control On button.
3. Examine the power cord to ensure a good connection between
the rear-panel AC input connector and the wall outlet.
4. Check the electrical circuit and breaker.

Kenwood Audio Amp KA-5040R - remains in standby

Hi, Lost sole, i HOPE YOU FIND IT

Minwhile, when it works to know if you have a cold solder joint, hit the unit on the top or buttom to see if it stop working, mostlikly it will,
To fix this you must unplug the unit open the bottom cover, and solder joint that look broken off, moslity on the output stage or power supply.
What I think happening is when the unit heat's up the joint expand and doesn't do contact no more.

Another problem that this may be is a bad power supply, cap's, this can be check by freezing them to see if the unit starts again.

This is little trick of the trade, I hope this help
