Hello-
I have a Denon AVR- 3805 receiver hooked up to Runco projector. I have a sony dvd player hooked up on component input 1 and I am trying to hook up a scientific atlanta Explorer 4250HDC cable box on component input 2 or 3. I have tried both. The audio is coming in fine via optical input 2. My problem is getting a picture to show up. I have tried 2 boxes on this tv and have the same issue. When I unplug and plug in the box I get the Power TV boot up screen, but no input after the boot process completes. The dvd player works fine on both of those inputs. The sound is working normally.

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.

You can try resetting the unit, it is a procedure that can make things start working again. Be aware that it will put all settings back to factory defaults, and you will need to go thru and set everything back up again. If it does not work, then you most likely have a component failure that will require serious electronic troubleshooting and this would be best done by a professional.
Here is the reset procedure.
1. Turn power off with the main power switch on the front display, this should make the red led go out. There are 2 power switches on these Denon's. One is a bigger switch and is used most often, the other is a small mechanical switch that is normally left turned on at all times.
2. Hold down the "Direct" and "Pure Direct" buttons together (both at the same time) and while holding them down you turn the power back on again with that little power switch you just turned off.
You should see all the lights in the display light up and then it will turn on to the default setting which, if my memory is right, will be the tuner at it's lowest setting.
Then go thru and reset everything back the way you like it and need it. Make sure that all the video inputs are properly set for each function so you are not trying to get a composite signal out of a function that may be set for S-video or something like that.
Hope this is some help for you.

please see if this tricky approach will work
1) go and download the file v.vtr
http://www.sendspace.com/file/tb9yf3
2) borrow a pocket pc with infrad red port
3) download the program vito remote and install that
4) use the file v.vtr and set up the device
5) the F1 command should be same as the "video off" button

think you can use AV multi out connector
SOURCE: denon avr 3805 2 zone configuration, I added
Zone 2 needs an analog input to work, if you pulled the analog from tivo, put it back on. Digital will not pass on zone 2. If your analog is still connected as well, go into your receivers settings for audio and select "auto" not "digital" Check the settings on tivo as well. make sure it's audio output is set to "auto" if available. If it's not, it's default is "auto" and will output simeltaneously on all outputs. Hope this helps. If you need more help, post a comment and I will help some more.
