  Fault phenomenon:
  Is stuck on the screen of the irregular noise interference or the thin black line is accompanied by & other Brian & throughout; Noise.
  Misunderstanding of the point of failure:
  The failure phenomenon, there are a lot of people think that is caused by the poor anti-jamming capability of display power supply, think as long as a few change filter capacitor of the power source can be settled, some even considered a place of switch power supply switch tube problems, these views are all wrong.
  The cause of the problem and countermeasure:
  The real failure reason is usually between mouth tube high pressure and high pressure cap to appear the phenomenon of flint. Of course, there are a lot of maintenance personnel can quickly analysis of this is caused by high pressure mouth place lighter, but there are many processing methods are not quite right. Have people even to butter to the high pressure to prevent this from happening again on high voltage spark, though no harm for display in the butter, but the pressure value may not be very high, so very likely give other maintenance staff and users are hidden danger of electric shock. So it is best to use & other; High voltage silicon grease & throughout; Repair & ndash; & ndash; Before adding high voltage silicon grease to use no water alcohol makes first high-pressure mouth, hat clean (such as rust cleaning or change new cap) with the hair dryer to dry.
  In addition, the header of kinescope sometimes lighter phenomenon also can appear the fault phenomenon, only it will be at the same time accompanied by the image of the good with bad, at this time as long as the replacement of authentic tube can be done
