I hadnt been using the amp for a period of 4 months. it was discontected from a power source.
when i tried to start up the amp, the standby power switch doesnt cut off, on presseing the power button.
amp stays in stand by mode. unable to do anything about it.
finally left it plugged on to a power source in case the
humidity had got to the switches.
any ideas would be welcome.

If all your speakers are good ( try another set to make sure ) and theyre connected good at both ends but your amp is not-being-nice, I would say that it's either a blown output module/output transistors
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
STANDBY message. To turn the unit back on, use the front panel
When set to OFF, the RV-8 will attempt to function during a
momentary power loss, however software settings may become
corrupt and need to be reset.
When the RV-8 is in standby mode, pressing the button turns the
unit on and activates all zones that were active in the previous
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.
Do you mean that the display that show the audio source or mode doesn't turn on? Try shining a bright flashlight at the display and see if you can read it. If you can, then the backlight light bulbs have died.
Replacing it will be a pain but you may find a usable replacement at Radio Shack. Just measure the voltage that goes to the bulbs and find one with similar ratings. They are probably 12v lamps.You will need to remove the display from the front panel of the amp and desolder the old lamps. Getting at the bulbs is the hardest part.
Something doesn't sound right. The standby circuit is usually very simple. The "regulator" is just a transistor. Can you request and post the parts that he/she can't find. I should be able to get you a source or substitutes.
Can you tell me a but more about the circumstance you are using the Yamaha.
The speaker switch you are using also has a strict rating of 100wrms Driving it with the 145 wrms of the ax596 may damage the switcher. You also should have the protection circuitry of the Niles engaged to when using the configuration of the speakers you have.
If you are operating the amp at high levels into the speaker system(whether the mixer is red lining or not), balanced out by the SLV4 to 4 ohms, it may well be suffering from overheating, or has developed dry solder joints associated with running hot that is causing it to go into protection mode. Any amp has to work alot harder to drive a 4 ohm load, and with multiple speakers and impedance correction circuitry will be presenting a rather complex load to boot.
If you are using it in a commercial situation and running at higher output levels for extended periods, you may be better to upgrade it to a fan cooled PA style power amp that is engineered to operate under these conditions. Domestic HiFi is not built to cope with long standing high power operation and may well fail prematurely
If it is over heating, you may be able to overcome this by moving more air about the yamaha and reducing the power level you are running the system at. Happy to talk further with you about this. Let me know how you get on :) Cheers
Can you, or can someone you know, check for DC voltage on the speaker terminals when the amp is on, but not playing? Ideally, the meter should read 0mV with no signal, and certainly less than +/- 10mV. Anything over +/- 30mV is worth having checked out, especially if it changes as you turn the volume knob with no signal applied.
