How do I remove after image from my plasma?
After image will gradually disappear by itself when watching regular film or TV broadcasts.
You can speed up the process by:
- Set the screen on an ‛untuned’ TV channel (you’ll see snow on the screen). Set the Contrast on 50, Brightness on +20 and the colours on +20.
- Disable the power control to prevent the screen from switching off automatically.
- Set Picture - AV selection to DYNAMIC.
- Leave this image on for several hours (we’d recommend overnight).
The amount of time that is needed to remove the after image is dependant on the intensity of the after image, ranging anything between one night or a week.
