SOURCE: new home theater setup- no signal at tv using onkyo tx=sr605

This might somewhat help. Today I went back .. I went HDMI out of the Cable box and DVD player into 2 of the TVs HDMI ins. The digital audio out from each, straight to the receiver and things are working ok. All speakers are working OK. Sound isnt as loud or crisp but unfortunately I found no other solution.

SOURCE: Cannot get a connection with HDMI input

When the tv won't scroll to the HDMI inputs, it means that the tv does not detect a signal on those inputs. This either means the tv has an issue and can't receive an HDMI signal(very unlikely) or there is no signal being sent from the source(converter box) The first thing I would do is unplug all output connections from the box except for the HDMI output and see if this gets rid of your problem. If not, I would be more inclined to think you have a problem with your converter box than with your TV. You could also try using the HDMI ouput of a DVD player if you have one.

How do I hook up a HD satallite dvr to a av reciever dvd player and HDTV using HDMI cables


Things You’ll Need:
  • HD television
  • HD satellite or cable receiver
  • DVD player
  • Stereo receiver
  • AV cables
  • Cable connector
  • HDMI cables
Step1Examine the back of your HDTV. You will see a series of input jacks for AV cables, (typically color-coded white and red for audio and yellow for video), as well as an antenna input and one or more HDMI input jacks. There will likely be a number of them, but each one should be distinguished with a label ("video," "cable" or something similar). Step2Attach the cable connector from the cable or satellite receiver to the antenna input on the back of the TV. Step3Connect the AV cables to the DVD player, VCR, stereo receiver or whichever other component you wish to connect to the television. The cables should line up by color: place the white cable in the white input jack, the red cable in the red input jack and the yellow cable in the yellow input jack. All three cables from each component need to go into the same label input jacks. Usually, they will all line up in a vertical row. Step4Find the HDMI output jack on your receiver or DVD player (some receivers will not have them--they are necessary to receive a high definition signal--but can still play on the TV through the cable connector or AV cables). Attach one end of an HDMI cable to the output jack of the receiver and the other end into the input jack on the HDTV. Step5Turn on the TV. Access the menu with your remote, and follow any instructions it gives you. Your HDTV may require a few additional steps to complete the hookup of the receiver (though not all of them will). Step6Access the "input" button on your TV remote. This will allow you to switch the TV signal to one of the cable connections you have just made. For example, if you attached the HDMI cable to the first of two HDMI input jacks, the TV will flash "HDMI 1" on the screen to tell you that is where it is receiving its signal. Hope that helps..........

Suggest you google these connection interface types and work out what is the output types
if rca then use av input on tv

then use select input source on tv to switch to whatever you used.

Hdmi input not working


Do you have a second signal from your cable box going into the TV by a different port?
You can only use one or the other, not both.

No signal stuck on channel 2 with black screen. Model KDL37M3000


Are you connected to a cable or sat box, Are you connected thru antenna input on tv or a/v input. If connect to box thru antenna jack of tv do channel search to pick up ch 3 if box is set to that. If connected to outside antenna still do channel searsh but be sure tv is set to antenna. If connected via av or hdmi the cable or sat box is bad.
