LCD TV pixel faults

Despite the most modern production methods, the highly
complex technology involved in producing this type of device
means there may be individual or multiple pixel drop-outs (dead
pixels). This is rare, however.
For active matrix TFTs with a resolution of 1440 x 900 pixels,
which are each made up of three sub-pixels (red, green, blue),
there are a total of approx. 3.9 million control elements in use.
Occasionally one or more pixels can fail or become incorrectly
controlled because of this very high number of transistors and the
associated extremely complex manufacturing processes used.
