Cannot Get X1 Box to Output 480p (or 480i)

Hello,

I have a unique situation. I have a television in my kitchen that was purchased in that "in between" SD and HD period. It's a 480p (4:3) flat panel with no HDMI input. It has component, composite and S-Video (no coax). The previous box I was using with this TV malfunctioned and I picked up a new X1 box from Comcast. I bought an HDMI to Component adapter and set the adapter to output 480p. The issue is that I cannot get the box to output anything but 1080p. It is convinced that it's sending a signal to a 1080p television and there NO option to change it to 480p or 480i. It only gives me the choice between 1080p and 1080p60.

Is there ANY way AT ALL to force this box to output a 480p signal? I've tried manipulating settings, hooking the box up to other monitors, etc. I'm simply out of ideas. Obviously the TV is worthless if it can't be watched, but I'd rather hold onto it because it is the perfect size (and white color) for a custom "cutout" area in my kitchen.
