Yes I know what your problem is.
One of the two convergence chips has failed.

They cost about 20.00- 30.00 etch and you should
replace them in pairs .

They are normally on a separate P.C. board screw down
to a big heat sink and the prefix should read sk or stk... followed
by a number . if your handy with a soldering iron they are not to hard
to de-solder and replace with new. plus you will save 300.00 on
the repair bill.

if you have any questions just comment and i'll respond.

My new lg 3d tv is closng on top bottom and sides is there anything i can do to cure the problem


Could you provide more information? What do you mean when you say, "closing?" Do you mean there is a black band around the picture? If so that means the original picture is recorded at a lower pixel density than your TV will display.
In the past most TV program signals provided a picture dimensions (in computer standards) very roughly 600 pixels wide by 400 pixels tall. What this means is that a picture of that pixel size will display as a small, squarish image slightly wider than it is tall on a (now) standard 1080p LCD television--which produces an image 1920 pixels wide by 1080 pixels high.
That would be nearly unwatchable (picture too small) except for the fact that most TVs compensate for the relatively small size of "standard definition TV (SD TV, as opposed to HDTV) by enlarging the image so that the top and bottom edges of the picture touch the top and bottom of the TV screen. This will leave black bands on either side of the picture. Some LCD TVs will automatically stretch BOTH dimensions of the image, which yields a distorted, "sqaushed" image.
All my comments above apply to both standard LCD and 3D-LCD TVs, by the way.

How do i set the color for picture


Projection TV sets have two very common problems. One is convergence ( 3D/Warped video) the other is CRT fluid ( Dull Video). Below are more details for both items. Also, complete repair kits with instructions and repair support are avail from site such as www.TvRepairKits.com Common Problem #1) Convergence has gone out Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. This is a very common failure on these projection sets and a fairly simple DIY fix. All projection sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.

Muffled sound, blury picture


If your TV looks 3D, warped, or distorted it likely has a convergenge problem.
If however it just looks dull, washed out, redish, or if it looks like objects on the screen have halos the fluid in the lens has soured.
You can search google for parts or you can get the parts with repair instructions from sites such as www.TvRepairKits.com

I'm having trouble adjusting the picture. The left half is clear while the right half is blury.


All projection TV sets have two very common problems. One is convergence ( 3D/Warped video) the other is CRT fluid ( Dull Video). Here are more details and solutions for both.

Common Problem #1) Convergence has gone out

Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

This is a very common failure on these projection sets and a fairly simple DIY fix. All projection sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.

Common Symptoms include....

  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.
  • TV shuts off after powering on. Power light will blink. TV may also make a chirping noise.
Here are some pics of convergence problems.

Common Problem #2) CRT Fluid is Cloudy

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.

What causes the picture to bend and get blury where its bend is at which is usally on the top of the screen and the bottom of the screens


Projection TV sets are known to have two common problems. The first problem that is common to these sets is convergence failure. When this happens the TV will usually look 3D, Wavy/Distorted, etc. It may also shutdown and blink an error code.

The second common problem with Projection TV sets is dull video, halos around objects, white looking video, or red overpowers the screen. This is commonly caused by the fluid in the lens being clouded over.
