HDMI inputs do not show a picture. They worked but now do not. They display the setup program from the Onkyo AV receiver via HDMI output, but not when the receiver is pushing any other signal via the HDMI output.

Nope.

Not sure what unable to connect means..but I will assume you have the correct cable.

First make sure you have plugged the from the HDMI cable from the DVD play into the IN 1 HDMI port on the back of your Onkyo

On the Receiver
Enter the Setup mode
Select INPUT OUTPUT ASSIGN
Next make sure the HDMI monitor out is set to YES on the Receiver
Monitor out
HDMI Monitor - YES

Next you need to assign the HDMI INPUT to DVD
Select INPUT OUTPUT ASSIGN
HDMI INPUT
DVD - IN1
CBL/SAT - IN2

This may be your issue.

Next step would be to verify your television input settings.

Nice receiver!

Best of luck!

For adjustments to receiver you can always run a component or composite cable to your plasma tv. After adjustments are made just return to HDMI input.

I think this one is for the Onkyo wizards:

However I did find this 2 page hookup manual with nice notes at link listed below that may help you solve the mystery:

(seems you may have to assign the digital input)

Assigning the Digital Input
If there’s no sound, you’ll need to assign the digital inputs as
necessary using the setup menus on the TX-SR606’s display.
If you connect your DVD player to the AV receiver’s COAXIAL 1
DIGITAL IN, and your cable/satellite receiver to the COAXIAL 2
DIGITAL IN, as shown, it’s not necessary to assign the digital input.
The onscreen setup menus appear only on a TV that is
connected to the HDMI OUT. If your TV is connected to the composite video or S-Video MONITOR OUT, or the
COMPONENT VIDEO OUT, use the TX-SR606’s display when changing settings.

Thanks for using FixYa!

You need to assign the HDMI input(s) to the functions they represent, using the Front Panel Tuning/Preset control...

If you connect a video component to an HDMI input, you must assign that HDMI Input to an input selector in Setup.
For example, you could assign the “DVD” setting to “IN1”, and assign the
“CBL/SAT” setting to “IN2”.

Likewise if you use digital audio inputs...

Assigning the Digital Input
If there’s no sound, press the [DIGITAL INPUT] button repeatedly until sound is heard. The digital input is now properly assigned.
If you connect your DVD player to the AV receiver’s COAXIAL 1 DIGITAL IN, and your cable/satellite receiver
to the COAXIAL 2 DIGITAL IN, as shown, it’s not necessary
to assign the digital input.

Your Plasma's native resolution is 720P. Go into the Blu Ray's output setup. you can choose 480p 480i 720p 1080i and 1080p. Set it for 720p that should clear up the issue.You may have to run Component directly to the TV since you only have 1 HDMI input and you can run Digital coax or optical to your AV receiver for audio. On a 50" TV the difference between 720p and 1080p using "GOOD" cables cannot be seen by the human eye. Above 50, yes it is noticeable.
Hope this helps.

I've posted this other places. Hope it helps.

My HT-S6100 had a similar problem with my DVD player and some times with my Cable/DVR box. The signal wasn't getting received at the TV. So, first I changed the input jacks my DVD and Cable box are plugged into on the receiver (e.g. from HDMI 1 & HDMI 3 to HDMI 2 & HDMI 4). Second, I reprogrammed the Input Assignments to match (e.g. HDMI in 2&4). Third, I deleted any Input Assignments that weren't applicable. For instance, I'm only using HDMI connections, but there were Digital and Component Input Assignments programmed in. When I say I deleted them, I actually set them to "----" (just scroll through the options and you'll find this.) Finally, I turn on my video/audio sources (PS3 in your case) and let them load/warm up before I turn on my Onkyo receiver. It seems to be working. Good luck.

you have the output of the receiver going to the input of the TV?

i believe that you should be running the TV output to the receiver input to get your sound from the TV to the receiver and thus speakers.

the easiest setup is to just run your cable box and DVD player HDMI's into your TV inputs. then run another HDMI from the TV output to the receiver input.

My mistake, HDMI in is not routed to any other output but HDMI out
