Improvement
We inform you that the performance improvement of the power unit will be implemented to prevent the following
component failure from occurring.
The power of the TV set does not turn on due to the power unit failure.
The ceramic capacitor C7817 or C7818 in the power unit is damaged.
To ensure the margin, the capacity of the ceramic capacitors C7817/C7818 is changed from 1000pF/1kV to
470pF/1kV. And, the ferrite beads FB7803/FB7805 are changed to the jumper to avoid a noise from the decline
of the capacity of the C7817/C7818.
Servicing For how to distinguish the NEW power unit, please refer to the next page of this technical report.
The OLD power unit and NEW power unit is interchangeable as shown in the parts table below.
There is no change of parts code of the power unit. Please supply and use the OLD power unit first.
