HI,Thank you for using Just Answer my name is ***** ***** I will help with your question.When a denon product displays protect it is in protection mode to prevent further damage to the unit. It is sometimes caused by faulty speakers or maybe a wire got shorted while the unit was on. It is also caused when compents inside the unit have gone faulty and need replaceing.
I am just reading the service manual on the reset procedure could you unplug all connections from the unit except the power.
Thank you bear with me it is not listed in the manual and I will check elsewhere
Sorry i am searching all the databases I have and I cannot confirm the correct reset
I am sorry I cannot help would you like me to opt out and let other experts have a look at the question.
Sorry I could not help
I have searched and the only reference I can find to resetting the unit is to unplug for 5 secs it does not seem to have any other reset feature. I suspect that the output transistors have failed and that is why the unit is stuck in protect mode. I have opted out so other experts can have a look at it. I
