Amp is going into standby mode - Yamaha RX-V440 Receiver

Could have developed an overload fault in either the power supply or output stages. Thus a safety feature will not let it come out of that mode.

Hi Brendan, have you swapped the speaker from the left channel to the right one so that we can be sure that it is not the speaker? You can also try a hard reset:

To do the reset you need to turn the receiver on, then on the front panel of the receiver press and hold the "VCR/DVR" 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.

Resolder Horizontal section & SMPS Power Supply with Soldering Iron

Try this, not sure if the same would work for ya.

Swich off the amplifier.
Prior to the process check the wires connecting the speakers are not creating a short circuit which is apparently putting the amplified into a standy mode.

1. Press the "A" "B" and power key all at the same time and hold on to it.
2. The amp will go into a reset mode and will keep blinking till it gives a normal "click" sound and the amp turns on.
3. this process would take about 2 - 3 minutes.
4. You may then release the buttons.
5. If it goes into a standby mode again and does not power on, or the standby keeps blinking, get assistance from the engineer.
6. Once it is on, you shall need to do the resetting of alll the configurations done earlier.

Hope it works, it costed me 3k to get the job done.

Is it connected to Bluetooth ?

Unit is in protect mode there are a few problems that can trigger protect mode the most common is blown channel (shorted outputs). Sometimes one of the 15v regulators may go bad causing imbalance of supplys triggering protect mode. Also sometimes a bad solder connection could cause unit to go into protect also. I work for Denon authorzied repair center in Michigan if your nearby and Shipping to Michigan is economical let me know [email protected]

sub can be detecting signal from your amp. maybe your amp has some small output when in standby mode. some amps throughput signal from satellite boxes when they are supposed to be off.
try shutting off that signal source as well.
good luck
