I have the same issue with my new LG 47lv5500. I too have time warner settings of 1080i but the sound on hd channels comes and goes. Picture is fine. When I switch back to non hd channels the sound is also fine. I'm also using just the HDMI cable provided with the tv from the cable box to the tv. HELP!!!!!!

Try a different HDMI port on your TV.

I had the same issue and i hooked my time warner cable box up and turned it to an hd channel and it comes in perfect so i set the output to only 1080i and now i can view every channel perfect

On this TV there is only one input for any HD resolution. Input # 5 is the component input i.e. red/green/blue cable. Just get the correct cable and match colors from cable box to TV this will allow the TV to display 1080i resolution ( only one this TV supports ). FYI you will also have to connect the red and white cables to the appropriate inputs to get any sound because red/green/blue connectors are just for video display not sound. Once your connected you'll be able to access video # 5 be sure to set your cable box to 1080i resolution also. I hope this helps later J.

Press menu on remote and tab over to settings
Scroll down to tilt correction

you have to make the alignment for all 3 formats....standard....1080i...and 480i

probably not without a video card update, or more memory..double check the memory allocation issues..this is a complex installation

For me it was the cable box settings...

I'm not a tech person, so take this for what its worth. I had the same problem with my Vizio and my Time Warner Cable HD/DVR box using the HDMI cord connection. HD channels were always fine, and non HD channels were fine until I went to an HD channel and back. When switching back, the non-HD channels would be shifted to the left as you describe. After much back and forth with both Vizio and Time Warner (each saying its caused by the other), I stumbled across the following fix...

I went into the cable box (scientific atlanta 8300) "settings", under "display," under "output resolution." There was a list including 480i, 480p, 720p, 1080i, and "auto select." I unchecked both 480 options and left 720 and 1080 checked. Problem solved. The other "Display" menu settings are as follows: Picture Size = Stretch, Aspect Ratio = 16x9.

Hope this helps.

I had the offset left issue for non-HD channels with my Panasonic 42" plasma, using Comcast HD cable box. Went into the configuration menu (to get there with the newer Comcast boxes, you have to turn the box off, then hit the menu button on the box immediately after). You will see on the menu a resolution (probably says 1080i), then below it a "4:3 override". Our said 480i. When I changed it to "none", so that it stayed 1080i, it worked! It also works by selecting 480p, but then the picture is stretched.

Yes. This problem comes about by actually pressing the center ring accidentally during normal viewing. Just press and hold the left or right side of the ring until the pciture straightens itself out again (if the black portion of the screen is to the right of the picture, press the right ring; if it is to the left side, press the left ring).

are you using scientific atlanta cable box by any chance?
