By jestine yong on april 7 2008 if you have the flyback tester then it would be easy for you to test the horizontal driver transformer. Un pequeno nucleo un transformador economico y muy durable y un transistor de media potencia es todo lo que se requiere cualquier fabricante que opera con logica comercial se olvida de hacer innovaciones en ese sector. What is a driver transistor.

More than small signal transistor. A weak drive might cause the hot to turn on or more likely shut off too slowly greatly increasing heat dissipation. I saw a switching transistor whose pins were shorted i replaced itas well as its.

The hot conducts until the start of horizontal sync and then is abruptly. There are many reasons why the horizontal output transistor hot shorted in crt monitor. The horizontal oscillator which controls the driver stage begins to turn the horizontal output transistor on approximately 30 35 us before horizontal sync as shown in figure 3.
