Problems viewing the computer monitor, like no other with a symptom of high tension may be due to several reasons. A faulty light bulb, a faulty video preamplifier IC, a power failure water heater, ripped the signal cable G1 negative voltage was too high (-120 completed and higher), it was the problem CRT board, a lack or low voltage and G2 therefore do not cause the screen, but with the current with a high voltage.

In this article I will show you a failure or a problem of low voltage G2. First,You must confirm that if there is a high voltage present on the screen. You can use a high voltage probe to use the anode voltage (24 kV) to measure or you can try listening to the noise at high voltage (if you're experienced enough) times the screen switched on if the current high-voltage then your focus should be on the screen voltage (G2) of the circuit. If there is high voltage, so I will explain in another article.

How to confirm whether the strain was present at the pin G2 of the Board CRT?Through your positive probe (red probe) for section G2 and the negative probe to cool the power on earth, you must be registered in certain readings of the counters. For your information, if certain types of computer monitors, the multimeter to the point G2, which would cause the monitor to power due to impedance loading of equipment. When a measure of G2 said low voltage DC 20 V (voltage of G2 is a good half-way between 250-300 + volts DC) is the next step we need to do isthe problem, isolate G2 to see if the loop is pulled down to the focus of tension in the flyback transformer / voltage divider screen that had gone bad.

Turn the power off and G2 unsolder wire board CRT. Place your sins accordingly (red probe cycle G2 and black probe to the cold ground) Now turn on the screen and begin to see the speedometer. If the reader gets is about 20 volts or more is a bit 'so suspect a defective Flyback. Can alsoTry to control the tension of the screen Flyback adapt. As has already been published on Flyback therefore must be replaced. You can also use a cheaper way to use to resolve. Using a screen Buster blur to add to defeat the original focus / video cable and use the cable from the monitor blur buster to act as a focus and G2. So, with this method, recently developed G2 strains could settle back to its original position, and you get a screen when the screen is on!

Now, what happens ifView from the surveyor Results 250-300 + volts DC, when the circuits G2 wire tension check-out? This is a very clear indication that there may be elements that the design of the G2 voltage to 20 V DC. Experience, covered the type of resin high voltage ceramic disc capacitor (typically in the range 1-3 kV) causes a wide range of displays will not be a result of the condenser to pull out the tension G2.

If you measure the high voltage capacitor with a capacity digitalmeter or meters, but the odds are very high that sounds good (within the range of skills). The truth is that you can count meter digital capacity is the value of test of skills, a strong trend in that high-voltage capacitor breakdown when under full load or stress. Capacitor can be accurately tested by a meter special Sencor analyzer capacitor LC103.

The cost of the meter is very high, so what I did, I have a Kyoritsu insulation tester was purchased forcontrol of high voltage capacitor applications. Focusing only on the capacitor leads during the test, and press start, a good capacitor will show charge and discharge more than a few, but those ruins would have remained high and should not be dismissed.

Shame about replacing the high voltage capacitor made of G2 voltage returns to normal, and troubleshoot computer screen. Hope this article, and you're invited to drop by the website of electronic repair tips and secrets for learning every day.
