Everything was working fine, tonight i turned on my denon and i no longer have a picture on tv1 if i change the source to dvd i have a picture but no sound. i am trying to watch tv through my dvd player. please help, i am at my wits end.

Your denon amp amp does not match and work well
in some players for instance "Samsung" no pictures
and sound via HDMI input. Only replacing players
to another brand such as LG can fix the problem.

Have you checked to make sure it didn't restart your entire system? If not you'll have to double check everything is connected correctly, turn everything on, and change the channel on the TV back to whatever Composite video or HDMI setting it was plugged into...then make sure the Denon receiver is set to Cable

make sure your speaker to your sheron sound isnt to close to it .also if dvd player is the source then move away from tv will demagnatize the tv theres a magnet in them

The video cables--the green, blue, and red ones must be connected from the video OUT portion of the DVD player to the Component 2 video IN of the Denon. It could be the handshake between your Denon and your television. Do you have anything else to connect to the Denon to see if you get a picture? How are you connecting the Denon to the television? Make sure you have your television on the proper input and check the cables going between it and the Denon.

We would like to guide you through the connection process,but depending on what kind of receiver and TV you have this process may vary.Visit our "How to connect receiver" page here:http://www.dishnetwork.com/SupportSection/setup-receiver.

Once we have everything connected correctly, check what channel or input yourTV is currently on by powering the TV off then back on and noting the channelor input that appears on screen when the TV is powered on.

Steps for getting picture on TV1:
If you are using a Coax Cable to connect the receiver to TV1, check thereceiver's back panel for the output name. If your receiver has a "TVCH 3/4 out" (non-ViP Receiver): Tune TV to channel 3 or channel4, if it has "Home Distribution" output (ViP Receiver):Tune TV to channel 62 or 75. If using non-Coax (RCA,Component, or HDMI) to connect receiver to TV1, cycle through the inputs untilpicture appears (this information may appear on the remote sticker), mostTVs have a "TV/Video", "Input", or "Source" button.

Steps for getting picture on TV2:
Access "Modulator Setup" from TV1 by pressing "menu"then 6-1-5. Tune TV2 to the channel that appears under "TV2 Out" onscreen. If still no picture, change the "TV2 Out" mode fromAir to Cable, or if it's already on Cable, change it to Air. Then change thechannel of TV2 to what is now displayed under "TV2 Out".
If the issue is only on ONE receiver, unplug the DISH receiver for10 seconds and plug back in. It may take up to 5 minutes for the reset processto be completed. If you still are not getting a picture, connect anothercomponent (VCR, DVD Player, etc.) to the same TV, using same cable, same input,and same channel to see if it works. If it works give us a call at1-800-333-DISH (3474) for additional troubleshooting, if you don't get apicture with the other component, replace the cable.

Hope this steps help, and thank you for being a valued DISH Network customer!
