It also naturally follows thathigher panel resolutions contain more pixels. To create acolour image, each pixel consists of three tiny coloureddots (known as sub-pixels), one each of red, green andblue. Each one of these dots is precisely controlled by theelectronics of the TV to produce the picture.Whilst Panasonic maintains the highest standardsin manufacturing technology and processes in theconstruction of these panels, there are a number ofallowable pixel/subpixel failures that still allow the panel tobe defi ned as a good panel. It is not possible to guaranteeabsolutely no pixel loss.●Problem ActionsChaotic image, noisy Change the setting of “P-NR” in the Picture Menu (to removenoise).
