diagrams should not be by other substitutes. Other substitute may
create the electrical shock , fire or other hazards. Take attention to

barriers, insulation papers, shields and isolation R-C combinations are
correctly installed.

or may overheat the material, in this case, the power of television

electrical insulation.
