Illustration:
1. The unit of all resistors is
. K=1000 , M=1,000,000
2. The power of all unmarked resistors is 1/6W.
3. The unit of capacitors is
F commonly. "p" represents for pF. If there is no additional
illustration, the working voltage of capacitors is 63V.
4. This diagram only illustrates the basic and typical model. Exceptional parts or part circuits may
be different from the fact circuit.
Note:
1. As the parts marked with are relevant to the whole-set's safety, the replaced ones must be the
same with Service Manual.
2.The circuit enclosed by = = is connected to the AC power directly. While repairing, the service
man should connect a buffer transformer between TV and AC power to avoid electrical shock.
