Video dropout I purchased the AVR-400 in December. For the past 2 weeks the video will go blank while either watching via satellite, a music audio with a dvd video output, or with just the dvd input. It starts fine, but after 15 to 30 min the tv goes blank and says there is no video input, check the connection. (Same message as if the receiver were off). The audio stays on, but I have to either select a different input and go back, or turn the receiver off, then back on to get the video back. The receiver is connected to a Samsung 40 inch panel tv via HDMI

SOURCE: No output

Probably a input switching relay problem. When you switch inputs you should here the click of a relay, do you hear that click?

SOURCE: no HDMI video output from AVR-588 receiver to plasma TV ???

You can also use a digital coax cable (color orange) to go into coax 1 for DVD coax 2 for cable box. Just make sure to set the coax in input settings. The coax cables are a little cheaper than the optical cables and work just as well.

SOURCE: Denon AVR 3805 video problem

Some of these Denons do require a firmware upgrade, but it is a very complicated process and you use your computer to do it thru the RS-232 port if this model has one. I can check on Monday to see if there are any for this model. I work at a authorized Denon repair center and fix lots of Denon receivers including this model. I just can't remember the specific details of every model of receiver I work on.

The only end user procedure you can try is the reset. If you try this reset procedure please be aware that all the settings you have made will be cleared and the unit will go back to the factory settings. You will need to input all of your custom settings.

This is no guarantee that it will solve your problem, but it may be worth trying. Sometimes the microprocessor software gets corrupted for unknown reasons, and a reset will clear out that type of problem.

With the power off you need to press and hold the "Pure Direct" and the "Direct" buttons on the front of the receiver and keep holding them in at the same time, then you would turn the power on while still holding those two buttons in. Once the unit turns on and you see and hear it turn on you can let go of the two buttons you have been holding in. Your receiver should now be reset, go ahead and make sure you assign the proper video inputs to the source you are using for the TV. Your owners manual should explain this. If you need help with it let me know and Monday I can look it up.

If this does not help you probably have a problem on the video input board, it has several IC's for switching and a buffer IC as well. It is controlled by the main system microprocessor also. The actual problem could be any one of those or even a bad voltage regualtor or transistor. It is not anything that the end user can repair unless they have experience in electronic trouble shooting. it also requires the proper equipment to troubleshoot with.

If you have found this information to be valid and useful, a "FixYa" ratings would be appreciated. That is the only reward I get for the help I offer here.

Thanks,

Dave

SOURCE: How to Connect HDMI Components with AVR 3805 as Hub

In reference to the comment you added to our chat session:

Just connect your receiver to your TV using the same cable your receiver is currently using to connect to your TV, be it Composite, S-Video, or Component. Just switch your TV to that input when you need to set-up something on the receiver.
