56FW53H
REASON
With the introduction of the standard EN61000-3-2 (Harmonic noise on the supply). It
has been necessary to add a ‘Power Factor Correction circuit’ to CTV’s produced
since the beginning of 2001.
ACTION
This has resulted in the following alteration to the circuit diagram on models with serial
