    Protect means Amplifier is in protection mode due to some problem in amp out section and requires qualified tech to fix it.

Blingking Light or Protect usually means that there is DC appearing in output stage and is protecting Connected Speakers.
It can be faulty Output Stage (Bad ICs/Transistors/Resistors/Capacitors) or Faulty Power Supply.

Working on These types of Problem is not user friendly at all.

Advising to take local Authorized Shop.

DENON UD-M30 CD Player is displaying the word PROTECT and will not function. Any ideas how to fix this problem? Many thanks.


HI:
Usually when a receiver goes into protect mode, there are several reasons, One is there is a bad speaker connected to the unit, this will cause the unit to to into protect mode, try disconnecting all speaker from the unit and turning it on if it does not go into protect then one of the speakers are bad. Another reason is the power output Amplifier IC is shorted inside the unit. Another reasons could be that speaker wires are touching each other and causing a short. Disconnect all unit connecting to the unit and try turning on, if it stays on and no protect then connect them including the speakers one at time until you determine which is causing the error. If it goes into protect with nothing but the unit on then the Output IC is bad and the unit needs servicing.

How do i reset my Denon udra m1o tuner amp from protect mode?


Protect mode can not be "reset". This mode means that a problem was detected in the final amp stage and the unit has been shutdown to prevent further damage. The most common cause of this is failed output transistors. Plan on a parts cost in the $20-$20 range for this repair.
