Re: Turns off after 4 secs or so....From Green to Red,
Receiver turns on Green but on pressing button again for red light standby, red light will not come on for this Denon receiver. Recently light came on saying Panel Lock is on. I was not able to get tuner to work.

While working it stops and flashes red approximately
2 seconds interval Causes Protection circuit is activated
depending on the temperature of the surroundings Remedy Switch off the power supply and power on
after the temperature have reduced. While working it stops and flashes red approximately
0.5 seconds interval Causes 1.Using speakers having less impedance
than the specified. 2.If speaker core wire touch each other Protection
circuit is activated Even applying power red flashes 0.5
seconds interval Cause Amplifier circuit has failed Remedy Switch off the power and contact denon
replace all the electrolytic capacitors in the power supply. i had the
exact same problem with mine and once i replaced the capacitors it
powered up and stayed on and worked perfect. these capacitors tend to fail as they're of poor quality. this fault is very common on denon receivers, especially the later models.
This is a short or unstable ohm load. Remove all speaker wire connections to see if the amp will stay on.
If the problem goes away when disconnecting the speaker wires try this:
1) Check volume level on zone one and zone 2 if connected. If it is too high the amp will go into protect mode and shut off exactly as you described.
2) Make sure no wires are touching any other wire or the metal surface of the amp. This will cause a short and send the amp into protect mode.
had the same problem... turns out the copper on my red and black speaker wire (on the speaker, not receiver end) was touching - causing my receiver to go to standby (self-preservation probably lol). i pulled the wires further apart so the copper ends weren't touching and that solved it.
Having too loud sound cannot damage the unit, the loud maximum sound is design for that unit, when its brand new one or 2 years old its okey.But when 2 to 3 or more years when voluming the maximum the it create a vibration that cause the "solder crack" and results intermittent sound goes on, goes off, that is your problem. You open the unit and got to supply section reheat or resolder the resistor, capacitor diode, transistor and most of all switching IC. when finish, go to audio section, do what u did in the supply section.Bear in mind not tosolder it causes trouble. When reheat all the solder, your unit is good as new.
