Power Input Only.
Salvaged from a Denon AVR-X2600H. This unit was periodically going into protection mode without any speakers hooked up. I was able to fully test each speaker output and each HDMI output and the unit seemed to be working fine. I was able to keep unit on long enough to do a software update but returned after a couple hours to unit in protection. I’m not experienced enough to diagnose and hoped for an easily visible fix. Please ask any questions and if you would like me to test something with the multimeter let me know.
