    Can't figure out how to get my Kenwood KR 595 receiver out of standby mode? Help!

  • Ron Bower Jan 26, 2009

    I had a friend bring one of these units over to me and it did the same thing. I did a little searching and found a few people talking about the output transistors Q17-Q20 so i checked them and found 2 on one side shorted. So i clipped the leads and then it powered up but only one channel would work obviously. I then pulled them out and did some searching for replacements when doing this i found another post where a guy who had purchased a service manual mentioned he replaced the 2 output transistors and then they blew again. This got me wondering if i spend the money to replace these transistors if mine will have the same problem.



    SO with nothing to lose i tore the unit down and i got under the board, discharged the 2 power caps and decided to remove the 2 good transistors from the good working side and move them over to the other side. After i did this i put the whole unit back together and then plugged it in. After about a minute or 2 the good transistors blew.



    SO without a service manual i know there is a problem further before the output transistors. I think in the preamp stage causing the bad channel to overload and blow out.



    Sometimes audio amps can over drive speakers, short the voice coil in the speaker and this can cause the output transistors to blow. In this case just the transistors have problems. Normaly replacing them will fix it. My problem is somewhere before the output transistors. But now i know.

KR-V6050 I cannot get audio to work on radio, video or any other setting. Also the red standby light stays on all the time, even when the power switch is turned off. Alan


Check the input / output connections are in the correct places. The red standby will stay on when the unit is off showing that it is ready for use. To confirm, turn the power off at the wall. The red light should go out after a few seconds.

Receiver stays on stand by


Turning On and Standby
On the AV receiver, press the [ON/STANDBY] button.
On the remote controller, press the [RECEIVER] button, followed by the
[ON/STANDBY] button.
The AV receiver comes on, the display lights up, and the STANDBY indicator goes off.
To turn the AV receiver off, press the [ON/STANDBY] button, or press the remote
controller's [ON/STANDBY] button. The AV receiver will enter Standby mode.

If you have any trouble using the receiver, a simple reset could solve your problem.Note that resetting the AV receiver will delete your radio presets and custom settings.
To reset the AV receiver to its factory defaults, turn it on and, while holding down the [VCR/DVR] button, press the [ON/STANDBY] button. "Clear" will appear on the display and the AV receiver will enter Standby mode.

Dear sir,my surround amp rear speakers are not working.model is kr-v5580.other functions are OK..Pl's help


1st try a test tone to the rear speakers. If you can not get a test tone check the connections again.. once you get a test tone, use the "mode" button on your remote to cycle through the surround modes and make sure you are in a surround mode rather than a stereo mode.

Kenwood Receiver KR-a5020 receiver won't come out of standby


The unit is in what is commonly known as "protect" mode. This means that a problem has been detected in the final output stage of the amp and the outputs are shutdown to prevent further damage to either the receiver or speakers. This should not be a difficult repair for a service shop. Expect a parts cost in the $25-$40 range. Add in the local labor rate for the total repair cost.

The amp is shutting down to prevent further damage. This is what is sometimes referred to as protect mode. There is a problem with the final stage of the amplifier. The most common parts that fail are the output transistors. Figure on $15-$40 in parts plus the local labor rate for the total repair cost.
