I just noticed that the analog inputs (e.g. Antenna A, Video 1) on my Panasonic TH-42PD25 are pushed off to the left so you only see the right 2/3rd of the picture. Even if I bring up the on-screen menu, it's pushed way to the left. The image is cut off and flush with the left-edge of the screen and the right 1/3 of the screen is black.
This only seems to happen on non-digital signals. For example, when using Antenna A, analog stations are pushed to the left and the left 1/3rd of the picture gets cut off. But if I switch over to a digital channel, the picture is fine and takes up the full screen.
I also tried playing a DVD. I've got my DVD player hooked up to both Video 1 and Component 1. On Video 1, the image is pushed off-screen. On Component 1, it's fine.
This problem is happening in modes Full, Just, and Zoom. In 4:3 mode, I can see the whole picture, but it is still pushed to the left.
99% of the time I am either watching my HD TiVo on the HDMI input or a DVD on the Component input, so I never noticed the problem. I know the problem wasn't there a few months ago. I just got the TV in October.
I have never messed with the service menus, so I don't think I've manually pushed the image off-center. I've tried unpluging the unit for 10 minutes but that didn't help.
Does anyone know what could cause this or how I can fix it?
