屏幕红基色过剩故障检查I2C总线数据是否正常?拔掉视放板,在视放板上测量显像管红枪输入电压,看看是否能够达到正常值?否正常否否不正常重新调整I2C总线数据测量显像管红枪输入电压,看看是否正常?检查180V供电电阻是R615,看看是否开路或者阻值增大?更换R615是更换显像管(1)屏幕
Excessive red base color fault Check if the I2C bus data is normal? Unplug the video board and measure the kinescope input voltage on the video board to see if it can reach the normal value? No OK No No Improperly readjust the I2C bus data measurement Pins red gun input voltage to see if it is normal? Check the 180V power supply resistor is R615 to see if open or increase the resistance? Replace R615 is to replace the picture tube (1) screen
