Minor Graphical Glitch with SNES on HDTV

[Zeifer]

I was wondering if anyone might know of a solution to a very slight graphical glitch I'm seeing when I boot up my SNES. I have it plugged into a Sony Bravia Model # KDL46S4100. Anytime the screen is full-on black (aka startup and some title screens and potentially more in-game), I have this yellow vertical bar that appears near the middle of the screen that stretches from top to bottom. It isn't solid in color but rather patchy and is about a inch or so wide and very dim so it can be generally ignored, especially since it appears to disappear when the screen is flush with colors.

I figured however I might as well ask just in case, thanks in advance for any advice, tips, etc.

Edit: Figured I'd provide further information to get the standard questions of out the way and directly aimed at the problem itself.

I'm using the original components that came with the system, no 3rd Party Devices.

I have the RF Adapter plugged into the TV with the Cable TV cable plugged into the Antenna spot on the back of the RF Adapter.

I have the RWY Cables plugged into the side of the TV at Video 2 ports.

I have the AC Adapter plugged in snugly into a power strip beneath the tv stand and not hanging over the end of the strip.
