Comcast Motorola cablebox problem, signal "locks in full"

We've had some signal degradation for the past few months on a our digital cable and the guy came yesterday and replaced something on the pole behind the house, and now the signal on my widescreen set is "locked in full". Basically I can't tell the TV to go to 4x3 mode because it thinks it's getting a progressive signal, and the screen is stretched out, filling the 16x9 display. I can't find anything in the box setup to change this, or in my TV's setup.

Has anyone ever heard of this? I dread calling Comcast customer service trying to explain what "locked in full" means.

What kind of Moto box? If it's the DCT6200; turn the TV on and your box off, press the Menu button on the box(not the remote). You should get a menu. Change the 4:3 override from "Stretch" to "480P". That might also work if you have other Moto boxes too.

That's odd. My friend had the reverse problem. His Moto box was outputting 480i through component and everything was stretched out and he wasn't getting an HD signal. I went into the service menu of the cablebox and changed the output to 1080i and the TV recognized whether it was SD or HD signal and the correct aspect ratio automatically displayed.
