In the liquid crystal displays inside. Have a piece of inverter, inverter is what role? The original LCD screen himself is not light, it is the source of the back light irradiation after screen out of the back light actual is lamp, also called a backlight, in the display inside some USES two and three, four and six tubes only, and liquid crystal displays of shapes and sizes relevant.

Lamp is very fine, installed in the internal screen display the two edges, by setting the device to light source to the screen surface, the two ends of the tube with electrodes, length as the CM, 34 CM, the lighting of the tubes in a moment general need light voltage 1000 V-2000 or so start high frequency voltage, lit up to 700 V or so commonly, so inverter is a can produce high frequency and high voltage power supply device of the lighting of the tube.

In the liquid inside of the inverter for Gateway W6501 and install the 1-3 GaoYaBao, outside the watch is a square components, it should be pointed out that at least one GaoYaBao inverter, because can light a lamp, is more of the two GaoYaBao assembly together can ignite two tubes, if the board according to have two or four GaoYaBao that must be used to burn four or six tubes only.......

In the actual maintenance due to all the detection circuit inverter tubes are with a control and protection of integrated circuits, so once a branch is out of order, will stop general work condition. In principle must be replaced the inverter, in order to protect the original and the integrity of the maintenance staff high some technologies will work to make the repair, but due to the elements are tiny and difficult and buy, can replace new. The merits of the inverter with use only the length of time to prove.

This is a quality is very good general 4 lamp inverter, used for 17-19 "LCD, after three years of use, the center has changed many, not a problem. So we through actual replacement, think that is a very good performance of the board.

Inverter must use good quality, because the long-term work in high voltage, after change can bring customer feel joy or trouble, especially in today's market economy, a penny a points goods, good goods is also there, but need to the test of the time to prove.
