Denon receiver has sound but can't find video input

SOURCE: No system configration display on AVR3300 since moving.

Make sure the two switches on the remote are all of the way to left most position before you try using the SYSTEM SETUP button - if the AVR is going into SETUP, the LCD display should be saying "SYSTEM SETUP". (I think that model does - most do).  also make sure that the Composite or S-Video on the TV's input 1 work from something else like a VCR, DVD player, ETC. rule out the TV and the cable first.

After days of frustration the real problem was with the cable box. It needed a firmware update. Following forum advice I disconnected the cable box power cord for a few minutes, reconnected it, allowed the cable box to reinitialize. Turned off receiver and TV. Turned TV back on and set it to HDMI connection, turned on receiver and all worked fine. Great picture and sound.( Needed to buy an optical cable to go from the cable box to the receiver to get sound from the speaker system. )--the dirtybird

It cant up-convert component to hdmi. Input and output has to be the same. However, you wont lose anything cuz hdmi and component are comparable

This is a site where you can download a manual. I'm not familiar with Denen however, you should be able to go out of satellite receiver(HDMI) to your receiver input(tv/sat) then to your HDMI input on tv. Your receiver might show video and sound through another port of receivers options, ie; video 1, video 2, etc. Check all putput options for your picture and sound. Hope this helps.

I'm having the same problem with my Wii output. The manual for the Denon AVR-1312 says that analog video signals (i.e. component/composite outputs from the Wii) are not converted to digital video signals (i.e. HDMI output from the rcvr). I'm running only HDMI to a projector, so the video signal is essentially lost. The fix appears to be to run an additional composite cable all the way to the projector. Sounds like your fix is the same. No Wii tonight! :(
