I got an Denon AV receiver in that immediately goes into shutdown. Plug
it in, no display. Hit the momentary power up switch, relay clicks by
small power transformer, display goes through two different displays,
relay clicks again and display goes mute. It says nothing on the display
about protection or such. Non of the outputs seem to be shorted.
Ot seems like a classic case of outputs shorted and the unit shutting
down, but the outputs are not shorted and the display does not say
protect before it goes blank. I resoldered up the main board and no
change. ESR'ed the caps and nothing jumped out bad. DOn't have the print
yet but that next if the customer wants to pony up more bucks.
Any ideas on the shutdown? I'll post the model number latter.
