Hello,
Its usually not a fault that you will see unless somethings burnt up. This is solid state electronics and you don't see this stuff go bad. But in the meantime try disconnecting the speakers and see if it still goes into shutdown and at the same time have a dc multimeter attached to the speaker outputs. If the unit comes on and you don't see any DC at all or very very little B+ on both speaker terminal sets then you may have a defective speaker. If you do see dc then that's why the protections coming on so you don't blow out your speakers. If you don't have any equipment or don't have any electronics experience I would then take the unit to a repair person for an estimate. Good Luck

Blue led power light blinks even after shutdown


What operating system are you using? When the power led continues to slowly blink, that means that the laptop is in standby mode and not fully shut down. In Vista, if you hit the power button on the laptop or the power button under the start button, it is configured to go to standby and not shut down. Make sure to hit the arrow all the way to the right and select shutdown from the list of dropdown options.

Denon AVR-4802R automatically shuts off in multi-zone mode


i had the volume of the multi-zone tuned too high and was attenuating it in an external control box. Once i took the multi-zone volume down to -25db, the problem went way. My main zone was operating around -35db so did not have the problem.

Screen shuts off after two mins, tap scratch pad to restart, why?How can I stop this?


if it is just the screen shutting off and not the power, your computer is either going into standby mode or the power settings are acting up.

what operating system are you running? has this been happening since you have had the notebook, or did it just start doing this? if it just started doing this, did you install any new hardware or software (including operating system updates)?
