When I press the STANDBY/ON button, the unit turns on for a split secnd and the automatically turns off. I have checked all the speaker connections and they look good. I have also unplugged the received for 30 seconds and made sure the impedence selector is set accordingly but this doesn't work either.
This was happening to mine also, all of a sudden. This solution came from the owners manual. Sure enough, the impedance selector was stuck in the middle , between 4 and 8 ohms....I also, made sure the speaker wires were not touching each other at the splice. Problem fixed. B
The unit fails to turn on when STANDBY/ON is pressed, or set in the standby mode suddenly soon after the power has been turned on.
The power cord is not plugged in or the
plug is not completely inserted.
The IMPEDANCE SELECTOR switch
on the rear panel is not fully set to the
upper or lower end.
Firmly plug in the power cord.
Set the switch fully to the upper or

Does the display show you are in protect mode , or is a light indicating that? The unit automatically switches to standby when the
"Hardware" - "Power Management" - "Auto Standby"
setting in the Setup menu functions are set. The protective circuit function may have been activated.
If this has occurred, "AMP Diag Mode" appears on the
display when the unit is turned on again, and the unit
enters diagnostic mode. If the results of the diagnosis is
that there is no problem, the "AMP Diag Mode" display
disappears and you can use the unit normally again. If
"CHECK SP WIRE" appears on the display, the speaker
cables may be short-circuited. Make sure bare speaker
wires are not touching each other or the back panel of
the unit, then turn the unit on again. If "NG" is displayed,
immediately unplug the power cord from the wall outlet
and contact your dealer.
• The protective circuit function may have been activated
because the temperature of the unit rose abnormally.
If this happens, then the power will continue to turn off
after you have turned the unit on again. Make sure the
unit has plenty of space for ventilation around it, wait for
the unit to cool down sufficiently, and then try turning it
on again. This is out of your users manual.
General suggestions are to remove all speakers and speaker wiring with unit off. Turn on and see if problem has stopped. If not, let unit cool down if warm and try again later. If problem is still there it needs repair shop work. I fht problem went away, shut off power and connect one speaker at a time and testing. Keep adding speakers one at a time with power off and see if a bad speaker or wire set can be located
You can reset all to factory settings, which may help;
unplug power, put back in switch on with power button.
Then press together "tape", "CD" and the power button.
You may need to reset the clock before it will work.
If you need the manual, here is the link;
check page 26 for the reset if not clear - nothing else in there that seems to be related, but you may find something i missed.
Hope this helps :)
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.
You can set the speaker impedance in the Advanced menu. See page 45 of english manual (it can be on different page in other language manual). In standby mode, on the receiver (not on remote!) press STANDBY/ON while pressing and holding STRAIGHT button. THe "ADVANCED SETUP" should show in the LCD display. Now use PROGRAM +/- buttons to navigate the menu. Select "SP IMP." which is speaker impedance setting. Press STRAIGHT to select the correct value. Options are 6ohm and 8ohm. 6ohm setting means 6 and less, so select this option. Now you can turn the unit off by using STANDBY/ON. Now when you turn it on again, it will use these new settings.

How do I get the main unit to recognize the subwoofer?
Wireless connection will set up automatically when you switch on both the main unit and subwoofer.
Sometimes you may encounter the problem that the main unit does not
recognize the subwoofer. Try the following process to solve the problem:
They are heavily interfered by other wireless home appliance
such wireless network, TV etc. Move the subwoofer to another place, the
main unit will auto detect & recognize it.
Switch off the main unit and the subwoofer and then switch on
them again. The main unit should recognize the subwoofer automatically.
If neither of the above works, try to pair with them manually.
In standby mode, press and hold the button on the main unit (PAIR flashes on the display screen.) to activate signal transmitting.
Press and hold the PAIR button on the rear of
the subwoofer (You will find the LED indicator on the subwoofer flashes
in blue and green alternatively) to activate signal receiving.
The wireless connection will set up automatically and the main unit should recognize the subwoofer now.
What speakers you have connected? This receiver supports only 6 and 8 ohm speakers (not 4 ohm). Also check if the ohm settings are correctly set in Advanced Setup (in standby press on the front panel STANDBY while holding STRAIGHT button). In this menu check the setting SP IMP. (speaker impedance) if it maches your speakers (6 or 8 ohm). Disconnect all inputs and also all speakers. With nothing connected, try to increase the volume. If it still will power off, the unit is probably faulty and should be repaired. If it does turn off only with speakers connected, check the speaker wires and the speakers, the problem will be there.
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....
POWER MANAGEMENT ON, OFF
"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

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.
If you have bare wire going into the receiver's output terminals, make sure a strand or two of wire is not touching the other terminal. That can short out the outputs, especially when you turn up the volume, which increases the voltage present at those terminals. That would cause the receiver to shut down as a saftey precaution.
After few sec when you turn on your receiver did you hear a click noise ? if yes your receiver is OK not in protection mode if no click noise is output protection in that case you must return where did you buy for service and update firmware a lot of update
However you can reset your receiver and debug the DSP section ( digital signal processor ) as follow

2. After " Clear " is displayed, the preset memory and each mode stored in the memory are initialized and will
return to the factory settings, and turn to Standby mode.
Now turn back on and check if it work or not and make sure check input mode such as analog or coaxial or optical input if stil no sound then debug DSP as follow
To set in DSP debug mode
1. Press and hold down DISPLAY button, then press STANDBY/ON button while the unit is powered ON.
