Denon receiver won't power on- blinks green then turns solid red.


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.

hope this helps?

Unit only stays on for 4 seconds then turns itself off.


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.

Insignia nsr2000 on/off problem.


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.

Getting clear audio to televisions from a soundboard


I think you should buy a video sender. It will take audio from your audio console and send wireless to a free channel to any free TV channel. No cables!

Here's one on ebay:

Start up it gets to receiver on the displayit shuts off and Power indicator starts fashion red to green


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.
