Diagram tube activation new method ----- Activate CRT

Keywords: imaging tube activation new law The color TV developing tube is normal, but the brightness of the developing tube is not high, the image green has a tail of the image when the brightness and contrast are increased. It may be aging of the image tube, and the gate can be determined by the imaging tube to add the filament voltage. Place the multimeter in the RX1K gear, black table pen gate. Red Table pen picks up the hiosis). A generally preferred imaging tube has a resistance value of about 1kΩ, and the significant image tube resistance value is above 10kΩ. The image tube can be activated using the following method. As shown in the drawings. Add 8V to 9V voltages to the filaments. The 110V voltage can be used with the switching power supply voltage of the television, and the power is 8 minutes, and the interval is activated once, and the image tube returns to normal. It should be noted that this method should be used to monitor the activation current should not exceed 30mA, and can be controlled by adjusting the resistance of the damper resistor R. If it is activated, it can be tested several times. Each power is not too long. If the single gun aging can be activated separately, we have used this method to activate too much image tube, the effect is good, so introduced it to everyone here.
