Hello, I think that you've got a problem in the relay circutry or a logic problem. tell ya what I ve got the service manual and schematic for the reciever. the engineers at denon where ahead of there time when this company started. they designed the equipment around what they wanted the specs to be for signal to noise and discrete audio channels. each of the sound channels from the component and composite inputs is given its own bus and amplifier channels. these paths are also common to the reciever/tuner outputs. one question though you mentioned that the composite/component video paths are not switching from the input to the output youve designated, and that the monitor checks good. do you have another video source,either digital or analog that you can input throgh another channel to see if it is infact a switching problem. try that and let me know. I can give you help with the switching circutry form the schematic if need be. believe me I know It took me about a week to track down the service schematic for this unit. Denon doesn't like giving out info unless you are an authorized repair center.

I am a Tech in Michigan and have worked on lots and Lots of Denon AV Receivers. These units have Protection circuits for Overcurrent, Dc Protect, 15v Regulator inbalance, Rail Voltage Inbalance, Low Ac Voltage, Low Standby Voltage and Thermal Protection just to name the ones I remember. My guess is you Probably have either Poor Intermittent solder connections or Amp is not Ventillating Properly. Make sure you leave room above Receiver to Vent and You are using no Less then 6 ohm speaker Impedance per ch. Refer to Speaker Impedance chart on back panel . [email protected]

hello runj69 your receiver is going to standby because you have a problem in the output ckt, the first thing is to check the connections to make sure no speaker are touching and if not you need to repair the output ckt, most of the time are the xtors.

Hi, this is a power board issue. remove the cover and make sure that this unit doesn't have blow fuse. if the fuse is fine, you will then need to replace the integrated power/ main board.
