My set has just come back from the engineers for the 2nd time and still is suffering from an image persistence problem. This can be seen mostly in dark scenes where there is a contrast of light and dark. The problem causes lights to have very long smeared tails and on camera changes for the old picture to remain visible on screen as a ghost over the new picture. An example of this is a face is on the left of the screen and nothing on the right. then it changes to a face on the right of the screen. This time there is a ghost of the face on the left untill it fades away. Basically I need to know if this is my eyes or do all sets have the problem.
