    Yes there is a reset facility but i doubt it'll work.



    Power-off using the small power switch on the front of the amp (NOT the illuminated switch).



    Hold the speaker A and B switches and re-power the amp by the same switch as above.



    You can let go after the main display starts flashing.



    xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx



    If your amp looks like it's going to work as normal (ie the front display lights up as it should etc), but then the amp goes into protection mode when the anti-thud circuit times out, then I know what's likely to be wrong.



    It's one of the power amplifier channels which has gone faulty.



    I just found this out after having this problem with my AVR-1906.



    I took the amp apart and de-soldered the suspected channel power transistors (centre channel in my case).....and hey-presto! it fired up as normal (obviously the centre channel would be out of service).



    I have ordered the replacement transistors from Farnell (UK) at a miserly cost of around £2-£3 each.



    Just waiting for them to arrive.



    An alternative is, if you don't use all your channels, take the transistors from a known working but not needed channel and swap them over with the duff ones.


    Hope thats of use!

My sr5004 marantz receiver has gone into standby with the indicator is blinking how do i get ride of it


If the red led is blinking fast (8x/second) the power supply is likely damaged and the unit will need to be serviced. If blinking slow, the most likely cause would be a shorted speaker connection. To help find the cause, unplug everything including the power and speakers. Connect only the power and try to turn the unit on. If the light doesn't blink, you know you have a shorted connection. Power off and connect the inputs and then power back on. If the light is not blinking, you know the problem is with an output connection. Just find the bad connection by process of elimination.

No power output or display.green standby light flashes.


Sounds like either a blown mainpower fuse or the thermal fuse for the power transformer. If the protect circuit was kicking in, the display would light up, but then turn off with a red blinking light. the green light with no display means the transformer is not getting power.

Red power light blinking on my denon avr 1907, tried reset procedure, no speakers hooked up now and it still goes from green light to blinking red light and shuts off...Any clues?


This is a protection mode. The receiver protection circuit detects an internal problem like missing power supply voltage or blown channel and shuts down the receiver. You need to bring the unit to a repair facility.

Power light blinking


Send it for repair. The receiver has a problem with power supply or a bad channel.

Goes to standby with fast blinking red light after 5 seconds


From my experience you need to replace the Hi power module

Display gone, no longer functioning


Green light but no display- most likely main transformer is gone (60%), 35%- blown main fuse, 5%- bad display or power supply. You are lucky if unit is still under warranty. Solution- repair shop.

Power Button Flashing Red


Try unplugging the entire unit and letting it sit for 5 minutes. See if this helps. If not, you need to do a complete reboot, which will cause you to lose your settings, but will probably solve your problem. To do a complete reboot, you will need to hold down two of the front bottons on the front panel. I'm not sure which, so either consult your manual or see other posts here which describe the reboot process for Denons. Hope this helps.
