Switches to standby at high volume

I experienced this problem when I first got the thing, I went through some menus and changed some things (cant remember what). Working fine for about a month, I unplugged to re-arrange my living room and now its back to switching to standby when i get to a certian volume level. Im only using front left and right speakers, simple right? I guess not. Is this thing busted?

Re: switches to standby at high volume

First you should check is there something improperly connected. If malfunction still occurs, check is there cooler inside, and if it is, is it working. That seems like heating problem.

How do I get the electronic digital display to light up.

Hi Dudley, I would suggest that you try the following reset:

To do the reset you need to turn the receiver on then on the front panel of the receiver press and hold the "VIDEO1/VCR" button while doing that press the "STANDBY/ON" button. You will see the word "Clear" in the display screen and the receiver will go into standby mode. PLEASE UNDERSTAND THAT YOU WILL LOSE ALL YOUR AUDIO & VIDEO ASSIGNMENTS ON THE RECEIVER PLUS YOU WILL LOSE ALL YOUR SPEAKER CONFIGURATIONS, SPEAKER DISTANCE AND ALL LEVEL CALIBRATION SETTINGS. YOU WILL ALSO LOSE ANY PROGRAMMED RADIO STATIONS IN MEMORY. Once the receiver goes into standby mode turn it back on and go thru the setup menu for all custom settings.

Thanks, JT

Porsche cdr22 volume increases and button will not dcrease

Most of these things use an IC to control things like volume etc. Chances are that will have failed.

Yamaha receiver picture disappears and reappears when changing volume

I had the same problem with HDMI input to the RX-V373 from a DirecTV receiver. The RX-V373 volume display and menus on the screen are HD only, which forces the monitor to switch modes when viewing SD.

My solution was to turn off 480i and 480p signals from the DirecTV receiver, and also turn off its native output. The DirecTV receiver then upconverts SD signals to HD. Changing RX-V373 volume then doesn't affect monitor video mode.

My B&K AVR 202 will not come out of standby.


Check the speakers first. Remove all the speakers from the amplifier and switch ON the amplifier. If the amplifier switch ON from standby without any trouble then any one of the speaker is damged or the wiring to the speaker have some problem. . if it doesn't switch ON from standby there is internal hardware faulty.
IF so Please take it any good electronic reparing shope near you. Becuase you hve to check the voltages at all the outputs of the amplifiers. In this amplifier user can't do any thing. To work wit this amplifer need a throuh knowledge in electronics. If you do someting wrong the amp will became irreparable, because its amplifier stage work in high ampere power supply.

My pioneer VSX-1016 shuts itself off during loud portions of a movie. I have checked the speaker wiring and have clean connections. Any other ideas?

Yes, evaluate the load presented to its amplifiers by the speakers. If you have any speakers running parallel on the amps instead of one per amp channel you could be experiencing temporary unacceptable drops in impedance.


From page 57 in the manual...

• Turn down the volume.

• Lower the 40 Hz and 125 Hz equalizer levels in the Manual MCACC setup on page 34.

• Try switching on the digital safety feature (put the receiver into standby, hold down the SYSTEM SETUP button on the front panel and press STANDBY/ON to switch between SAFETY ON and SAFETY OFF

. If the power switches off even with SAFETY ON selected, turn down the volume.

Cannot take unit out of standby mode. Brand new unit. . Was playing at relatively high volume and then it bounced to standby and now won't budge. Originally switched it by using "selector" button as I was...

It sounds like you've either cooked the output stage or blown a fuse or two. Some amps use relays to protect speakers whilst others use old fashioned fuses. Check the rear of the amp to see if there are fuse holders. If there are then unplug the unit and check each fuse. If they are marked as mains or power leave that alone it's for the 120volt input. the ones you want are usually marked left and right or just speaker. If the speaker fuses are cooked then make sure you use the same rating when replacing. Also check your speakers, they could be cooked too. Unlikely but possible. Some makers hide the fuses internally which can make things dangerous for anyone poking around. If in doubt leave it to a tech. If the fuses are blown replace them. check your speakers and plug in and swich on. If the fuses blow again go looking for a repair shop as you've possibly blown the output stage.

Power on but no display on Denon AVR 3705

By now the folks who asked this have certainly solved their problem, but in case anyone else has this same question:
If the color change from red to green on the Power button indicator light and stays that way, the receiver is most likely working fine, it's just that your front-panel display is OFF.
1. Check the DIMMER mode by pusing the buttom on the front panel -- it may be set to OFF.
2. Push the PURE DIRECT button on the front panel (or remote control) -- it may be ON, which turns off almost all of the front-panel display. (Alternately, change the AV source, which turns Pure Direct OFF.)
HOWEVER if the power light flashes rapidly, the amp's overload protection circuit may have been triggered by a feedback loop or other problem, such as a shorted or bad cable connection. Turn off the power and unplug the receiver. Look for problems starting with shorted speaker wires or cables. Then make sure the receiver's not still hot (wait 5-10 minutes to let it cool), and remove obstructions or anything blocking the top vents. Plug it back in and power up again. Immediately change the Source selector to something unconnected, and turn the Volume DOWN just in case there's a feedback loop (hum/squeal/noise that can overload things and cause the protection circuit to trip again). If you can see the display, go to a low level (around -50dB should be fine) before the delayed speaker amp output clicks on. Then carefully switch back to the problem source -- if that's the problem, switch off again immediately and re-check all of the cable connections at both ends, the receiver and the source component, and make sure you don't have a feedback loop due to a recording device feeding back a signal. All VCRs and CD/DVD-recorders should be hooked up to the VCR, DVR or TAPE/CD-R "IN/OUT" jacks with IN being connected to the cables marked OUT on the deck and vice versa. (That confuses even us experienced guys sometimes!) Also, no MONITOR video or audio outputs should be connected to the recording decks, nor should the TV outputs be fed back to the recorders. The same goes for the digital IN/OUT jacks for CD recorders; use only the same number IN as OUT for each component (Optical IN/OUT #4 and #5 are the two digital IN/OUT pairs on the AVR-3803).

No Power

I mwas gonna suggest that you need the speakers attached but you stated later that it did the same thing with the speakers attached. The unit switching off after it checks its self is NOT a normal thing. TAKE IT BACK BEFORE ITS TOO LATE!! GOOD lUCK
