The TV high -voltage package, the authentic name is the output transformer, also known as the lines or lines. The high -voltage package of the display and the working principle of the TV are basically the same. Its main function is to produce anode high -voltage. In addition, focusing, acceleration, grids, etc.Voltage.
The TV high -pressure package is good or bad judgment
Determine the damage of the high -voltage package. When the circuit is not short -circuited, but when the voltage is not available, you can use the mule to short -circuit to promote the primary of the transformer. If the collector voltage of the row pipe is restored at this time, then 90%is 90%.The high -pressure package is damaged and accurate.
How much voltage of TV high -voltage package
If it is a high -voltage package of a TV, most of them are: 14 using 115V21 with 115V25 with 130V29 for 140V, but these voltages are not absolutely correct.Some models may have a deviation of about 5V.
How to debug the TV high -voltage package
1. Use a short wiring first: one end of the ripple of the first word, the other end connects the ground wire of the imaging tube, hold it on the insulating handle of the upper child, insert the word head into a high -pressure hat, and discharge at the high -pressure hat.2. Gently remove the high -voltage package with an electric soldering iron, and then welding the fixed feet and wires of the high -voltage bag. Pay attention: remove the pipe seat inch, and the appearance tube should be particularly careful.The method of installation is exactly the opposite: first welding the high -voltage package, and then welding the wire.Clean up the high -pressure mouth of the appearance tube: If there is a rust, clean it with wine.The hot air is dried, pay attention to the temperature cannot be too high.
TV high -pressure package failure
1 There is more dust in the air.During the work of the TV, the dust was adsorbed around the high -pressure cap due to the electrostatic induction of the high -voltage, which reduced the insulating performance; 2 air humidity, high -pressure caps were not sealed, and TV maintenance entered the humid air inside the high -pressure cap;There is a burr to connect to the high -voltage line, and the burrs will produce cutting -edge discharge phenomenon, burning the high -pressure cap rubber and aging.Therefore, the high -pressure fire in the TV is mainly caused by the humidity of the weather.
How to discharge the TV high -voltage package
High -voltage discharge is simple.First break the TV of the TV and electrical sources, use two long handle screw knives, and one flat into the high -pressure cap of the TVs image tube, contact the deck inside, and the other contact with the black leaf coating outside the image tube.And contact the metal part of the screwdriver in the high -pressure cap, and the discharge is completed.Although the discharge in this way is more violent, although the voltage of the high -pressure cap is very high, the current is small, and even a fewh is not available, there is nothing wrong with it.
