Hi - I didn't realize the picture you submitted was from YOUR set... I thought you were using it as a reference to what your cables looked like.
I now see that you have it connected incorrectly (just like I said).
You have the WRONG red cable in the Pr jack.
The two black (red and white) plugs should be in the AUDIO red and white at the bottom.
Click the picture below to see what two to switch.
The way you have it now - you are using the composite jacks - which do not allow for the best picture.
You can keep it the way it is now - but you should know the resolution is nowhere NEAR 1080p (more like 420) and you're using a video cable for an audio signal.
If you look at my first answer...
It states to verify the audio cables (also describes the cable ends being a different color for the audio cables)... and you stated you double-checked and it still didnt work.
Well - according to your picture (and subsequent follow up) I can see the bottom two jacks are red and white... and in the first pic you have the red video cable in the red audio cable jack.... and an audio cable in the video jack. A video cable will transmit audio, but an audio cable will not transmit video signal.
From the top - you should have...
GREEN banded white plug
BLUE banded white plug
RED banded white plug
White banded black plug
Red Banded black plug.
This will give you the best HD resolution from your cable box. Right now, you are only able to get SD (standard definition) with your current wiring in your last post.
As always - if you have additional - Just Ask.
