Problems often encountered display spots also appear to be magnetized. The main reason for their produce are: monitor near magnetic materials is magnetized; after moving the monitor, so that the machine deflection coil displaced, resulting in poor color purity; degaussing circuit damage. While some display itself with a certain amount of degaussing function, but for more serious magnetization on some powerless.
For color due to the external magnetic field disturbances caused by pure bad, the available external degaussing degaussing. Degausser available, can also be made. In an emergency situation, you can find a used meter (1A ~ 5A may be), remove the voltage coil, its "door" shaped wire core profusely, only penetrate a T-coil core and coil and then plug in the power cord and switch connector terminals on the two coils, and then wrapped it tightly with plastic sheeting to. But either degaussing law, must pay attention to safety. After power constantly shaking hand degausser, gradually close the screen, on the site can be repeated with a magnetic, and then while shaking degausser side back to the screen from about 2 meters then turn off the power. Every power-on time not too long, not good if a degaussing can be repeated several times. // This article is from China and tighten network hardware players www.ChinaDIYer.com reproduced please specify the color after moving the monitor caused due to pure bad, you can open the back cover will show the deflection coil to restore the original position, and the deflection coil screws . For color due to the degaussing circuit damage caused by pure bad machine, you can first check the thermal demagnetization resistance is damaged, remove it by hand as issued a "buzzing" sound, for the thermistor is bad. With a multimeter to check the pin resistance value, such as resistance is less than 8 ohms or greater than 50 ohms then the RTC within degaussing resistor element is bad and should be replaced. Such as degaussing resistor properly, you should focus on examination degaussing coil leads, plugs, sockets and loose contact between bad.
Also as degaussing resistor short circuit or leakage will cause boot failure burned insurance, we should pay attention.
