I just got a replacement SA 8300HD from Brighthouse. My old box had numerous problems, including the fact that the HDMI output did not function properly (as a result, I used component video to connect that box to my TV).
The HDMI output on my new box works fine, but for one small but annoying problem: whenever I press the Guide (or Settings, etc) button, the screen "shrinks" to a 4:3 aspect ratio. The black bars appear and it even looks as if part of the picture is cut off.
Anyone have any idea how to fix this? I've rebooted the box to no avail, and I've tried to enter setup by pressing Guide and Info on the box with it off, but that did nothing.
Any help would be greatly appreciated.
