The timing of the replacement arrives, or the old CRT TV ignition accident successively

Replacement of cathode ray tube TVs with liquid crystal televisions and the like is proceeding with the issuance of the government's eco point and the complete transition to terrestrial digital broadcasting on July 24, 2011, but due to the successive ignition accidents of old CRT televisions It became clear that there was.
