Fault warning
Immediately cut-off, notify the maintenance professionals, to avoid accidents.
( 1) after starting up or use, hear” pops” sound, even the smell, if not immediately shut down, it may damage the components or the kinescope tube burst. This is television high voltage part in the ignition, the oxygen in the air in the electric spark generated a little under the action of ozone.
( 2) in the process of using TV suddenly smoke or Jiao Yan flavor, serious naked flames should be immediately cut off the power supply, removal of the surrounding natural objects, with fine sand or wet quilts, blankets and other textile fabric wrap TV, to isolate the air circulation, put out the flames, while preventing from burning and caused the explosion tubes.
