    watching a dvd last week, and it switched to the "red" shadow..
    I know it has something to do with convergence. But what can one do?
    Does anyone have the schematic for this? Mine was mfg August 2002.

    I have a 3D look on every channel and 2 items are seen with each on the screen. Though using flash focus should work out the problem, I still see 3 crosshairs at end of process what should I do?

    have you unplugged the set for a little bit then start the antenna channel setup , then start the auto focus convergence untill the cross turns white? , then exit the auto focus/ , in that order?

Picture looks concave ,mostly yellow,and double vision on words


Remove unshielded speakers or other metallic objects near the TV. It can cause picture distortion.
  1. Tune the TV to channel or cable program.
  2. Run the TV for at least 30 minutes.
  3. Press FLASH FOCUS on the front panel of the TV.
  4. A cross pattern appears and FLASH FOCUS begins to
    work. The adjustment is completed when the cross pattern becomes white and you are returned to the program you were watching.
You cannot perform any other functions until FLASH FOCUS has
completed its cycle. If you perform any other operation while FLASH FOCUS is in progress, FLASH FOCUS operation is canceled.

If after the Flash Focus™ feature has been performed, the colors on the FLASH FOCUS screen do no line up (converge), press the FLASH FOCUS button on the television to begin the cycle again. If the colors on the FLASH FOCUS screen continues to appear misaligned, service will be required .
NOTE: It is recommended to perform the Flash Focus™ feature about thirty minutes after the television has been turned on and keep the room as dark as possible.

The convergence amplifiers are likely blown.
