Open cover inspection, see this machine has been repaired. The airport block is LA7876N, which is rarely seen in the repair. Circuit power supply normal. Taking into account of maintenance staff inspected on the field circuit. Finally, to no avail, so directly on the repair Forum Search for information, find the fault phenomenon is a common problem of Panasonic HD TV, the majority of users said the failure is caused by the deflection coil failure, some netizens said the machine deflection coil to repair, so decided to try it.

That is, repair the machine deflection coil does not need to remove the coil, because such coil fracture basic in a place, namely the deflection coil on the left (from the direction of the tail plate) on the lower part of the junction slightly a little bit. It is with glue manufacturers firmly seizuring to see the break. And from the side of the deflection coil, can see the circle where there is a section of the coil exposing the adhesive, in the heat of the iron hook Duan Xianquan, heated side edge tugs, can easily will be broken open coil out (it is also proved that the coil took place here fracture),, use the same method to fracture at the other end of the pull out, then will be broken open at both ends of the connection, good insulation, repair work is complete.
