Your normal meter can t measure it. Also safety shut down circuits are added to disable the output stage should the high voltage increase to unsafe levels. Flat panel tv diagram of internal parts and circuit boards note. If your tv has lines across.

Crt tv circuit board diagram. The b voltage for crt monitor is about 60 to 80 vdc and for television is about 110 vdc it depends on sizes and model of the equipment too. Because of the key role that the retrace capacitor plays in controlling the induced voltage and crt high voltage it is often called the safety capacitor. In case the sinusoidal voltage is applied to x plates and frequency of variation is more than 16 hz the deflection will be a horizontal line.

Sharp 70ds 18smk2 crt tv schematics and circuit diagram rar. If the filament in the tube is not open circuit and if the flyback is generating high voltage this means the flyback winding that supply the filament voltage could have open circuit or even there could be a break in the protection resistor causing no voltage going to the filament. The cathode ray tube crt is a vacuum tube that contains one or more electron guns and a phosphorescent screen and is used to display images.

This lg flatron crt tv which is about ten years old unopened for any service was brought to me with a complaint that it is dead. Filament voltage for crt tv comes from flyback and is a high frequency ac volt. The amount of deflection is in proportion to the voltage applied to the pair of plates. If this voltage missing due to problem in smps or from the b voltage circuits itself then there will be no high voltage even though other components signals are working fine.

Samsung cs21m16mjzxnwt crt tv how to enter the service mode circuit diagram high voltage limits high voltage must be measured each time servicing is done on the b horizontal deflection or high voltage circuits. Sharp 70es03 04es schematic diagram rar.
