Denon Receivers are reliable devices that enhance the overall experience of your home entertainment and other systems. While most of the users have had a satisfactory and reliable experience with the Denon receiver, a few users have faced issues during their usage. One of the issues that have been reported by a few users is experiencing the Denon Receiver turning off immediately after they turn it on. This is followed by a blinking red light. If you are experiencing this issue, here is everything that you need to do and the steps that you can take to get rid of the issue.
This red blinking light is known as the Protection Light. It comes on when the current sensors and thermal monitors of the receiver detect unusual operating conditions. In some cases just doing a thorough checkup and restarting the receiver resolves the problem. However, there may be instances where it may indicate a deeper problem that needs to be fixed. Here are a few things that you can do to resolve the issue.
How To Fix Denon Receiver Turns Off and Blinks Red?
1. Give Receiver Some Rest
There is a possibility that the issue may be caused by overheating. In such situations, the circuitry automatically resets after a few minutes of cooling down. If this is the case, the protection light will go out after a while and you will be able to use the receiver just as you normally would.
2. Turn off the Power and Check Connections
Low impedance condition, a bad speaker, or a short speaker wire can also result in the appearance of protection light. In such a situation you will need to turn off the receiver and reset it. Make sure that you check all the wire connections to and from the speaker. Now if you turn on the receiver and you see the protection light going on immediately, you will need to disconnect the speaker wires at the receiver side before retesting.
If the receiver protection light does not appear, it indicates a problem with one of the speaker wires or the speaker. You can connect them one by one and retest to find if the problem is with the connection or the speaker.
3. Initialize the Microprocessor
If you have taken the steps mentioned above and you are still facing the issue of seeing the protection light, you will have to initialize the microprocessor. In other words, you will need to reset the device. You can find the procedure for initializing the microprocessor in the owner’s manual.
It is important to remember that resetting the device will erase all setup configurations stored in the system and you will need to set up the system again. So mark down your settings before going for a reset. This will help you during the setup process.
4. Take Your Receiver to An Authorized Repair Center
Just in case you are unable to do the reset yourself, or if you have done a reset and are still facing the issue, you will have to take the receiver to an authorized repair center. They will check the receiver and make the necessary repairs to get it back to working condition.
