Your convergence circuit has failed. The amps need to be replaced but most likely the resistors have also been weakened or have opened up. The other issue with doing this repair is getting the correct parts. You can go online and order them but in most cases you will end up with generics. Generics in the electronic industry are not like in the pharmaceutical field. Stay away from generic IC's and other generic electronic parts. Even if they fix the problem they will cause issues with resetting the computer parameters or they will fail premature. If you know an honest technician let them do the repair. If you put all the parts back in a can't get it aligned you will need someone to go into the computer anyway. Just make sure the tech is using original Sanyo amps and not generics. An easy way to tell is the originals don't have any numbers stamped on the back(heat sink area)of the IC.

Follow the color code green for green, red for red, blue for blue, ignore the yellow wire, also be aware that there is an audio cable that is red also that wire goes into the Right channel audio and the white wire goes to the Left channel audio

It is called Convergence. You have three CRTs. Red, blue, Green. When they are not aligned, you will see the individual colors. See if you can do some alignment in the users menu. Look for Converge or Convergence in the menu. Either under video or setup.

The picture is showing a double image and is distored.


The problem you are refering to is more than likely a convergence problem. The convergence circuit in your tv is controlled by an IC (integrated circuit) stk392-110 and it makes the 3 colors (red, blue, green) line up/converge together to create a clear picture. You'll know when this part needs to be replaced because the picture you see is 3d looking and possibly bowed on the top or bottom or on the sides in any or all 3 colors.

Yellow, blue and green ghosting of picture. Convergence mode will not allow realignment of the red and blue lines


Hi,it sounds like a light engine problem.Lcd Technology uses 3 chips blue,green and red that create the image ,when they start to fail color discoloration will occur.If it's an Dlp pay attention to sounds of buzzing,whirling and high pitch sounds because it could be your colro wheel.
