Have three different color images (red,blue,green)

This symptom usually indicates CRT failure. Projection TV's, especially older types use 3 CRT "guns" to project the image on the screen. One is Cyan or Red, one is Green and one is Blue. If the Red and Blue become weak or do not project, the Green gun overpowers the output of the other two. These three "guns" are aligned exactly on top of each other so when all three are correctly functioning, the correct colors are projected on the screen.

Basically there is a sensor inside, behind the lens. The lens captures the image and the sensor translates it for the computer's processor using RGB color (red, green and blue). Using these three colors you can create any color.

These procedures are from the owners manual, go into menu and then picture quality and then: Convergence The Convergence feature lets you adjust the TV’s three tubes. When the TV tubes’ images are precisely aligned, they create the color images you see on the screen. Over time, the picture can drift out of alignment (this is normal). If your picture seems fuzzy or has a yellow tint, using Convergence could correct this misalignment. Only one convergence is needed for all inputs, regardless of the signal format. Note: Make sure the TV has been on for at least 30 minutes (TV needs to warm up for best results) before starting Auto Converge or Red/Blue Centering. When you select the Convergence feature, a submenu appears with three options: Auto Converge Automatically aligns the projection lenses to self-correct color images. You’ll see flashing squares of color dance across the screen (this is normal). Note: After performing auto convergence, use the Blue Centering and Red Centering menus to fine tune convergence in the center of the screen, if necessary. Blue Centering Aligns the blue and green images to fine-tune the picture. Red Centering Aligns the red and green images to fine-tune the picture. Note: The ability to change channels is disabled when adjusting the convergence options. The TV must be tuned to a usable signal to converge the picture.

could be a couple of things. 1 the convergence is messed up, go throught the set up and make sure the blue and red "+" are aligned to create a white image, If using component input make sure the red is to the red the blue is to the blue, try different cables for the components blue and red. Try S-video or Composite, if the problem persists, check the menu to ensure all the colors are set even, if the problem still persists,then you may have a blown projection gun.

Your TV probably has several different ways of connecting video. One is component, which uses three cables. They are red, green, and blue (RGB). The video output on your DVD player will match this color scheme.

Another scheme for video is composite (because it combines the red, green, and blue into one cable). Composite video is usually a yellow "socket". It is simpler to connect, but the video quality is noticeably poorer than component (RGB).

Another scheme is S-Video. This is one cable (round and black), but you will see four pins inside the connector (and four holes in the "socket"). This accounts for the three cables in the component scheme with the convenience of having only one cable. The picture quality is almost as good as component as well.

In your case, there may be confusion between composite and component. If you have red, green, and blue sockets on both the DVD and TV, then make sure you use them and connect them color for color.

Now for the sound, this is simpler. Red is the right channel, and white is the left. Make sure you connect red to red and white to white. Then, viola, everything will be right.

I hope this helps.

The lcd polerizer(not sure this is proper name ) is bad.It has three: red,green,blue and one of them is bad. I also have a similar issue but only on the left side. Took it apart and found the bad one.

adjust the blue bias on the high voltage block .
it has focus and bias for all three colors

lg70 nice tv excellent processor just to bad there is no intensity control on color management oh well still better than what the three s are pushing block out the hype lg will be number 1 in a few years haters are starting to come around and well leds coming,

p.s. i dont work for lg just tired of losers bashing stuff because they dont own it.
im isf certified those settings are right on the money straighter than a ruler

basically we use RGB color system so it contains color like red green and blue....in ur web cam settings u only increased the content of red color and u decrease the content of green and blue...so pls take ur settings and put all three colors to a same number...it means u have number from 1 to 100 and u can give the red green and blue colors up to this limit....so put green in 32 and red in 30 and blue in 32......then it will b corrected

do they look like these:
