Home Theatre problem - help! "Unsupported signal. Check your device output."

[Pink Bits]

I have a problem with my home theatre set up. First of all, here's the gear I'm using...

Sony KDL-46Z4500 - 46" LCD TV
Sony BDP-S550 - Blu-ray Player
Onkyo TX-SR876 - A/V Receiver

Today, I went to play a Blu-ray disc ("The Big 4" concert - 1080i), but no video would show up on screen and just a message saying...
"Unsupported signal. Check your device output."

While the video wasn't displayed, I could hear the audio fine. I then tried another blu-ray disc and it worked fine ("Pirates of the Caribbean" - 1080p).

I played a different 1080i disc and then a different 1080p disc, and sure enough, for some reason the 1080p/24fps discs work fine, but the 1080i/60fps discs do not show video on the screen.

I have also had a problem with regular DVD's in the last few months too, where the audio is fine, but big blocky colours will appear on the screen (mainly greenish/pinkish colours).

I was thinking that it was the Blu-ray player at fault (and still could be for all I know) but I turned it off and tried my (crappy) LG DVD/HDD player just to see if the display was working on that one and it wasn't either.

This leads me to believe that the problem is in the A/V Receiver or the TV, but I'm not sure by any means.

I have not changed any firmware, any cables, settings, etc. Last week I watched the disc with no worries and a week later, it won't display video. It might even be something as easy as changing a setting to something, but I don't know what it would be.

Any help for this problem would be great. Thanks.

You will need to use a process of elimination to identify the problem. Were you running both BD players via HDMI through the receiver to the TV? If so, try reconnecting the players via HDMI directly to the TV, bypassing the receiver. Connect them to the same HDMI input on the TV the receiver is hooked to.

If the problem goes away on the 1080i discs and DVDs, the fault lies with the receiver. If the problem persists, it's probably in the TV. If it's still there, connect the receivers to a different HDMI input in the TV (assuming you have one). If the problem goes away, then you have a faulty HDMI input in the TV. If it remains, you have a problem further in on your set.

Good luck.

Check at what resolution your Blu-ray player sending out too.

I've done a few tests/checks and the BD player is sending 1080p resolution. I got a reply from Sony saying I should try 1080i, which I did, but it didn't work either.

I plugged the BD player straight into the TV and it worked, so I guess it has something to do with the Onkyo 876 receiver, although, why can I still watch 1080p Blu-ray discs but not 1080i ones!?

On your Onkyo set up set your video output to auto or through. Or it could be your Hdmi cable. Even if you run hdmi cable directly to your tv and it works it could be that your receiver does not like the Hdmi cable and is having a issue.
