Contact LG to see if known issue with the model number--in general this can be a communication problem between main board and panel, can also be a bad board that drives the panel (usually on one side of screen) and can even be the display panel (entire front screen unit) which is fatal from a cost point of view.
Someone has to open and inspect and then if finds something amiss order and replace boards to see if that cures the problem or not.
The tuner on the LG TV may be right on "the hairy edge" of being able to receive that signal. Therefore the processor won't acknowledge and display it. You may want to try the LG on one of the other antenna feeds were the TVs DO display that channel. You might want to try the LG with no other sets hooked up. You may have a problem with any of the following. - staple through a wire - cracked lead-in wire or damaged coax - problem with a distribution amp/splitter.
Hi, the aspect ratio is set incorrectly for the source material or the screen is simply set to 4:3 aspect (old TV size) manually. There will be a menu function or an aspect button on the remote for doing this. Set it to auto which is usually good enough for most viewing though the ratio may change during adverts and back again for the film on tv watching. This can be annoying so when on tv mode observe the ratio set when the film is on and manually set this ratio, usually 16:9. The display will normally tell you the ratio setting at the point of change so you can do this. I hope this helps.
LCD stands for liquid crystal display.These types of displays have been around for awhile and are commonly used with computers.One reason for their big popularity is the ability to produces a better picture than CRT monitors but also being much thinner. Pro’s
Low Energy Consumption – LCD monitors use very low amounts of power. This is why it is very commonly used in battery powered devices.
LCD screens also reduce the amount of glare on the screen which can be very beneficial if your TV is in a room with lots of light.
If an image is left on the screen too long, LCD screens are less likely to experience the image being burned into the screen. If this does occur, it’s easier to repair than other types of TV’s.
The viewing angle of an LCD TV is typically not as great as Plasma but the difference is not great enough to make a huge difference.
LCD TV’s can sometimes get dead pixels which aren’t typically covered under warranty. Although they are very small, they can become very annoying.
Brightness levels aren’t as great as Plasma and it’s not possible to display darks quite as dark.
Plasma technology hasn’t been as widely used as LCD in previous years but has become very popular in large HDTV’s. Although they have historically been more expensive than LCD TV’s, they are becoming more comparable in price. Pro’s
Brightness and color are the major advantages of Plasma TV’s. They produce rich colors along with very deep blacks.
Their wide viewing angles allow more people to be able to watch TV comfortably.
The pixels of Plasma TV’s are lit individually unlike LCD screens. Because of this feature, the pixels can be completely turned off to display truck black colors.
The lifespan of a Plasma TV is typically shorter than other types of TV’s. The lifespan can be extended by turning down the brightness of the screen.
Plasma TV’s are more susceptible to screen burn-in where an image is “burnt” onto the screen when left on the screen too long such as a network logo in the bottom right corner of the screen.
Plasma TV’s require a panel of glass to cover it. This glass can reflect light and make it difficult to see the picture. If placed in a dark room, this typically isn’t an issue.
Hi James, This could be one of two problems. I can't narrow it down any further without having the set in front of me. 1. The plasma panel or the componets which supply electricity to the plasma in the panel have packed up. 2. The video processing unit in the set has gone. As for the cost of repair, if it's the panel, buy a new TV. It'll be cheaper. If it's the component that supplies the electricity to the plasma on the panel or the video processing unit, expect to pay between 300-400 as a conservative estimate for parts. Labour would be another 100-200.
