No. As the US was supplanted by Japan in consumer electronics, Japan has been subsequently supplanted by Korea and, increasingly China, in consumer electronics manufacture, including TVs. In fact, Japan has become a net importer of consumer electronics. Had the earthquake struck further south, there are some LCD component factories that could have been impacted as well as two large size LCD factories. However, these facilities seem to be undamaged.
While the loss of life is to be mourned and the loss of housing and its contents has to be replaced, most probably the net effect will be neutral as the loss of production from Japan is off-set by the loss of demand as Japan rebuilds.
