I have a Denon AVR-589 that is going into protect mode that I've been trying to diagnose but so far have hit a wall.
I followed what unclejed613 had posted in this thread about testing to see which channel is blown and was unable to find one that is actually blown. None of the 10 pairs of transistors are shorted out.
There is mention of a protection trigger transistor however I've been unable to locate the correct one in the schematic. The only "DC Protect" circuit I can find is for the higher end 1709 on the 2CH Board. Which I'm assuming is the separate board for the 2CH "Zone 2" option that they had.
Any suggestions on where to go from here?
I picked this unit up used a couple weeks ago with no WAF. Now that it's busted it has an even lower WAF..
