20 Most Recent Kenwood VR-606 Receiver Questions & Answers

The receiver's out put sections are grouped in pairs. Front left and right in one output, rear left and right in second output, and center channel and sub output on the third. Sounds like a semiconductor or semiconductors have gone bad in the center & sub output.

WOOHOO!! I fixed this issue... same problem as everyone else has mentioned... to reset the Kenwood VR-606 receiver, unplug the unit. Hold the power button down and while holding the power button plug the unit in.
Say a prayer...
Then press the power button.
My display isn't working, but my speakers are working, and that's really all I care about right now... good luck to others!

It sounds like the problem is not with your VR-606. If you hear a hum from the sub, the problem is more likely to be in the sub's built-in power amplifier. However, it is worth resetting the amplifier to factory presets. To do this, unplug the power cable from the mains supply and reconnect whilst holding down the power on/standby key. If the hum persists, connect any powered speaker to the sub-out socket, power on and listen for the hum. If no hum then suspect the powered sub amp. Turn the sub on with no connection to the Kenwood VR-606. If hum persists, the sub has a problem and will need to be replaced or repaired. By the way, you said there is a low frequency hum through the 'speakers' for about 30 mins. Is that all speakers or just the sub? Hope this helps. Cheers, Don.

You need to get it to stay turned on before you worry about sound.

Generally speaking, an amp attempts to protect itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.

Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.

You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.

If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.

If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.

Check for loose speaker connections at the speaker as a root cause for intermittent shutdown.

if the unit hasn't been worked on for a few years then chances are it has what's called "cold solder joints".......you need to have the boards re-soldered.......also, this problem could be caused by bad filtering capacitors that cause fluctuations from the power supply .....also can be caused by components overheating and so it shuts itself down to standbye mode to protect itself from further damage.....in any case...you need to have it looked at by pro's unless you know how to troubleshoot it yourself.....good luck

I imagine if you disconnected the optical audio cable you would still see sound settings varying on the PC, so it proves nothing.

You need to make sure the Sound Card Digital Output is at a correct sampling rate. Find its digital settings and try 44.1khz, PCM. Experiment wit hall settings.

Hi, the transformer is probably a part of the power supply and is not usually the cause of this behavior. The fuse is blowing because of a short. The short is most likely in a power transistor or diode, but you might want to try disconnecting the speakers to make sure it isn't one of those. If there is no change after disconnecting the speakers, find the power transistors and check for signs of damage. Also check for a burned diode on the power supply board. Replace any burned transistors or diodes. Please let me know if you have more questions, and thanks for using FixYa.

you need to select the digital optical input or even easier would be to select the auto sensing efature ok good luck i would walk you through it but im sure you will figure it out ok :)

The most common problem found on FixYa for Audio Video Receiver's is:

My receiver say's "Protect" or turns on then off. What's wrong? Seven times out of ten it is a shorted speaker or speaker wire. To determine your exact problem, the first step is to disconnect all speaker wires "at your receiver" Next: Turn the receiver back on. If your receiver still says "protect" or turns off, it needs to be serviced. If your receiver stays on; reconnect your speakers one at a time and power back up after each speaker. You may find that after reconnecting all speaker wires it works! Most commonly the small braids of wire from the + to the - have touched and have caused the problem. In some instances, you noticed the problem only when turning the volume up. either way, make sure the exposed wires to your receiver are no longer than 1/2" long and are completely under the screw down terminal or slide in. When you've found the wire or speaker with the problem, your receiver will go back into "protect" At this point, disconnect the wire from the speaker at the speaker that may be causing the problem then test again.* Note* Make sure speaker wires do Not touch each other as this Will cause a short! If you turn the receiver back on and it stays on, you now know the problem is in your speaker itself. To test your speaker, you will need a multimeter. Set it to ohms resistance and touch the speaker terminals, if there is a short internally the meter will read "1......" If it's an analog meter, it will peg to the right. There's your problem. Now, within any speaker there are quite a few possibilities as to what could be causing the problem. Most common is a blown coil and the speaker needs to be replaced. Some speakers have internal crossovers (usually floor standing speakers) and may have a shorted or burnt board (usually very visible brown burn marks on the board) and can possibly be repaired if your handy with a soldering iron. Now, if you disconnect the speaker wire at the speaker and it still says "protect" Check your wire for the obvious cut or nail thru the wire if possible. If your system has wiring that runs behind walls, you may need to use your meter again. Disconnect the wire at both ends, keep the ends separated, put your meter on ohms resistance and touch probes to the + and - wires at one side. If the meter pegs to the right or reads "1...." the wire is shorted and needs to be replaced or repaired at the short. Hope this helps.

Without additional equipment it can't be done. As i see your VR-606 pure analog device, and you trying to somehow use 5.1 sound from HD STB that is on HDMI put on RCA connectors of your VR-606. It is impossible without converter from HDMI to Analog audio or something likethis, best way to buy new receiver with HDMI input and TV neither Receiver with HDMI out oportunity. Then you will have your home cinema. In your current setup probably you can play only with stereo from your stb.

When you say 'plugging it in', do you mean power or signal?

You have a major clue: external components affect it. Try to figure out which one(s). Then abalyze what's different about it(them). Are different power sources (outlets) involved? Only certain cables? Sometimes different AC plug polarities can cause the relative grounds in the units to be diffrerent and when you join them with RCA cables they'll have hum or static problems.

Another thing: don't overload its convenience outlets with powering external gear. It only supports 150 watts.
