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 standards inmanufacturing technology and processes in the constructionof these panels, there are a number of allowable pixel/sub-pixel failures that still allow the panel to be defined as a goodpanel. It is not possible to guarantee absolutely no pixel loss.Problem ActionsScreenNo sound is produced • Is “Sound mute” active?
