Maybe it's me, but your comments are hard to understand.
Your cables might be a problem, but you won't know until you have a known good one to compare them all.
Here's a suggestion to determine if it's a cable, a source or a receiver problem. Take notes on all of the following steps.
To determine if your have cable issues do the following.
1) Take one known good source like your Blu-ray player and use a good Blu-ray disc as an image reference.
Disconnect the HDMI cable going from the Blu-ray player to your receiver and connect it directly to the TV. If you see a good picture, remove the other HDMI cables coming from your other sources to the receiver.
2) Disconnect the remainder of the HDMI cables from all of your other sources that are connected to your receiver.
3) Plug those cables individually from the Blu-ray player and connect each one to the same HDMI input that you used in step #1. Do the same thing for every HDMI cable you are using.
If the image from your Blu-ray player looks the same with each of the HDMI cable you have, then the issue is not the cables.
If the cables are all good, now you can use those cables and reconnect them to all of your sources and 1 by 1, connect each one of them to the same HDMI input you just used to test the cables in steps 1 and 2.
This will give you a reference for each of your sources. It will also remove the receiver as a possible source of your image problems.
Most Sony sets that I've had and used in the past had global settings that were present on each input. This means that, what ever you set your video settings to, it's the same for every input. Your set may be different.
