You have a component cable problem, most likely a loose RCA connector or one of the connectors switched. You have a 5 strand cable with two red ends. Be sure you haven't switch the reds - red next to white is for audio, the other red cable is part of the red, green, blue video signal.
In your model year, there is also a component cable splitter. Check the wiring on that and power cycle it as well. Not a 100% sure where it is mounted but the passenger side ceiling of the bay sounds about right.
