Denon Avr 4300h blinking light


Standard Member
My Denon AVR X4300H decided to shut itself down 15 minutes into a film, it has the blinking red power light.
I've tried disconnecting everything and still the same, it comes on for 2 seconds and shows cbl/sat then goes off.
I tried the "Initialization of the Microprocessor" & still the same.
Any info appreciated

Blinking red power light means DC protection. It could be related to power output stage or to one of many power regulators. Long story short, not an easy fix I'm afraid.

Is the unit well ventilated otherwise after a fix your going to have the same issue in a few months time?

I would try... disconnect everything except power lead, do a full reset see what happens. If it works then it is likely something to do with one of the speaker connections so at least you can move on from there in the diagnosis.

If it doesn't work with nothing plugged in then it's back to what @dobrykamil said sorry.


Happened to my 2300, had to send it back for repair and they said it was a dry joint on one the internal speaker connections.
