C5707 Transistor in BenQ T705 LCD Monitor




I don't believe it as most of the time it will surely work as this is a The Monitor has the same symptom again which is display shutdown after few seconds! Guess what? Fresh solder was applied to the high voltage transformer pins and I'm ready to "On" the LCD Monitor. Both the tuning capacitors found to be okay but there were dry joints in the transformer pins.

In this case, as usual after I have confirmed that only two C5707 transistors shorted, I began to test the tuning capacitors and check the pins of the high voltage transformer. I had come across quite a number of shorted C5707 transistors caused by dry joints in pins of the high voltage transformer. You also have to observe the high voltage transformer pins carefully. The reason why I emphasis on checking this tuning capacitors was because the capacitors have a high failure rate that could cause the C5707 transistor to go shorted.

However, from my experience, checking only the capacitance value doesn't guarantee that the capacitor is good unless you confirm it with ESR meter. If you do not own one, you can use the digital capacitance meter to check the capacitance value. Besides the shorted transistor, one also has to check the tuning capacitor for high ESR value with the help of ESR meter. The cause of the problem was usually a shorted one or two of the C5707 push pull transistors. This BenQ T705 LCD Monitor has a common fault of display shutdown after few you "On" for few seconds.

The Light Transistor




Daniel has built and designed numerous companies and hired, trained and managed literally thousands of contactors and employees. Infinity Group consisted of Infinity Financial Services, Infinity Productions, Infinity Home Improvement, Infinity Home Mortgages, Nase Consulting, Sunrise Charity Foundation, and the Wealth Building Foundation. References IEEE Lasers and Electro-Optics Society's Website OIDA (Optoelectronics Industry Development Association) Daniel Nase is the Chief Executive Officer of Real Estate Pros in beautiful Southern California and the former CEO and Managing Director of Infinity Group. Since then the popularity of Photonics has increased with numerous new components created by professors at the University of Washington.

This component was invented in 1998 by Daniel Nase when he took apart a standard LCD screen and used two laser pointers to cause the liquid crystals to change direction. Although this is not the other way to control light without an electrical input, further testing and optimization may lead to a revolutionary new type of computer that processes information at the speed of light. AND gates have two or more inputs and no output unless all the inputs are present. This component acts like an AND gate in electronics.

When liquid crystal is used in electronics, the crystals change direction to show a black dispay like on a wrist watch. The light transistor uses liquid crystal to change the direction of light when two beams intersect.
