<!-- from fixya rte -->Hdm1 cable hook up wher is it - Proton NT-3460 32" TV

Try the old cable if it works the new one is bad. I am assuming you set it to show HDM1, that generally is selected with the remote or one of the buttons.

Any hdmi port will work.

Power up all components. Select the HDMI 1 input on the Denon amp, and the HDMI 1 input on the TV. Additionally, run the old analog cables between the cable box and the TV. If no picture, select the input on the TV that is associated with the analog input from the cable box. You should have a picture at this point - but it will be a standard definition type. Check the settings on the cable box to change the output from "A / V" to Digital on the HDMI jack - if present. You may have better luck unplugging power / replugging in the cable box first - or calling the cable company if you can't find settings for this. Once you have the output of the cable box to HDMI, select HDMI on the TV. If you still don't have it working - try bypassing the Denon and go directly into the TV from the cable box. Try it with BOTH HDMI cables. Also - try different inputs and out puts (HDMI 2, HDMI 3, etc.). Discard any HDMI cable that fails to show video and play audio.

If you have flat screen t.v. go to the menu button and it should give options such as hdm1, hdm2, audio video hdm1, is cable you use the volume up and down button to select.

If the dvd player has an hdmi output, insert 1 end of the cable there and the other end of the cable insert it behind the tv into the hdmi input. Just make sure that both dvd and tv have hdmi to hook up both together .

I don't think that box has two tuners or a recorder.

I would not try that unless you can confirm both units will allow it.

it depend on what you are trying to connect its all in owners manuel cables should be listed too and what they are for. also mark on panell

Switch to another HDMI input

If you are using the HDMI input, you are using the best hook up that is available.
Is there a particular problem with the picture that does not look good?
