All of a sudden there is no sound when the cable/TV is on, though the picture is displayed. If I rotate the source to CD, while the cable box is still on, the sound for the cable/TV comes on, but no picture. Very strange, any ideas on how to fix this?

Here's an idea!
Most modern TVs have a remote control with various settings. Look for an option that allows you to change the screen orientation. This might be labeled as "Picture Mode" or "Display Settings." Find the "Rotation" or "Orientation" option and set it to "Normal" or "0 degrees" to correct the upside-down screen.
For the sound,check the TV's audio settings. Make sure the TV's volume is turned up and that no sound modes (e.g., "Mute" or "Silent") are activated. If you're using an external source device (like a DVD player or streaming box), ensure that the cables connecting it to the TV are secure. Check the audio settings on the source device as well.
If the issues persist, you might consider performing a factory reset on your TV. However, be aware that this will erase all custom settings and preferences, so make sure you're okay with reconfiguring your TV.
This sounds like you accidentally hit the input button on your remote. It will either be INPUT or SOURCE on you remote. Turn on your TV and source(cable box) and hit one of those buttons until your picture comes back
It sounds like the TV is having sync issues with your Sky+HD box. HDCP is the "High-bandwidth Digital Content Protection" that is used between components. It requires a sync between the devices to ensure that you are not trying to "steal" the video content you are watching. This intermittent message and blacking of the screen is good evidence that this is your problem.
Even though the HDMI cable worked fine on another set, I'd try a new one anyway. Some TVs and components are more sensitive than others, and a weakened cable may not show a problem on one set, yet show it on another.
Barring the new cable not working, check LG's website for a possible firmware update for your TV, and also try using a different video source, like BluRay and see you have the same problems.
Beyond that, it may just be an issue with the TV itself starting to die.
Sounds like you might have a defective unit, or the source that is connected to your tv (cable box, dvd etc) is going out. A lot of times if you have a cable box, glitches, loss of sound and/or color are because of the quality of the input source. Try changing the channel. If the problem is the same on any channel - or on your dvd/xbox, then it is probably a defective tv. You may be able to get it exchanged through LG. Hope this helps! Good luck!
If you're using an HDMI cable your display will automatically adjust the settings based upon the video source. Make sure that your source is capable of outputting 1080p. If it's an HD Cable Box or DVR, the maximum resolution it can display is 1080i. If you have one of these HD boxes, set it to only display 1080i as there will be a delay every time you change channels from a channel that is not naturally at 1080i.
If your source is a standard DVD player, it can only display images in 480i (or 480p if it is Progressive Scan) and therefore your TV will display the picture in 480 resolution. If your source is an upconverting DVD player it will display up to 1080p however, Keep in mind that DVD's are in 480 resolution and that regardless of upconversion (or upscaling, though improved, the picture will not be in HD.
The only way to achieve a true 1080p (not dpi... that's dots per inch... that's a printer term. The "p" is for Progressive Scan as opposed to an "i" for Interlaced) is from a 1080p source, i.e., a Blu-Ray disc player playing a Blu-Ray Disc with the use of an HDMI cable. Component Cables can achieve 720p/1080i only with your TV as it does not support 1080p over component cables.
As an aside, there are some media players that support 1080p output and some DirecTV Boxes and DVR's d oas well for 1080p Pay Per View movies.
Can you tell me which Cable box you are using?Which model/region?
The possibility is that the HDCP handshake could not have happend correctly and hence the issue. Try to connect to different HDMI input of TV from Cable box. If possible change the resolution of cable box and check video
From the looks of the TV manual you have everything right, so it's very odd you're running into this problem.
Have you tried swapping through the sources? I find with one of the TVs we have on display at work that any time I'm having some troubles with it I will change the source from PC to something else, then back to PC.
If that doesn't work then I'd suggest you try reseting the sound settings back to factory default. The instructions are on page 45 of the TV manual. From the TV menu select "Sound", then "Sound Reset", then either "Reset All" or "Reset Sound Mode". I would suggest reseting all.
Last option would be to try using the headphone jack in the side of the TV, though this is a last resort kind of thing since you would have to unplug it every time you wanted to use the cable box.
Same problem I had... My problem was with any HD input from PS3 (only HD device I have), the PS3 was fine on other televisions so I determined that it must be a problem with the TV in question. I fixed this problem by unplugging the TV, letting it sit for about a minute and then plugging back in.
Hi,
Probably you first have to determine if the "no sound" is the TV or your source (cable box). Try another source such as a DVD player hooked to the audio/video inputs of the TV, if still no sound then you have confirmed that it is the TV, if there is sound, then it is the cable box (in some cases it may be just the cables connecting the cable box and the TV; try wiggling it a bit, might just be loose).
If it is the TV, go through the routine of the setup/menu; look for audio, stereo, SAP, etc, try different settings (pls log down original setting in case no change and you have to revert back).
If all else fails, try the "thump test" this will help you determine if its a loose/cold solder problem inside the TV. Give your TV a good whack at the side, top or back, if sounds comes on even briefly, it's a loose/cold solder problem, if not then you probably have to have the unit serviced by a qualified professional.
Good luck and kind regards.
