The image of TV is dark


Hello everyone, in this video I want to show you how to repair this television Hello everyone, in this video I want to show you how to repair this television Hello everyone, in this video I want to show you how to repair this television This television has been damaged The image of this television is very dark The image of this television is very dark In this case, first we have to check on the board of CRT tail In this case, first we have to check on the board of CRT tail In this case, first we have to check on the board of CRT tail We move the selector of the multimeter to 1000 volts DC to check them We move the selector of the multimeter to 1000 volts DC to check them We move the selector of the multimeter to 1000 volts DC to check them We have to measure the voltage on the leg 7 of CRT tail We have to measure the voltage on the leg 7 of CRT tail We have to measure the voltage on the leg 7 of CRT tail We have to measure the voltage on the leg 7 of CRT tail The pin 7 of CRT tail is the screen grid The pin 7 of CRT tail is the screen grid The pin 7 of CRT tail is the screen grid Usually the voltage here is about several hundred volts DC Usually the voltage here is about several hundred volts DC Usually the voltage here is about several hundred volts DC Now the voltage here is 250 volts DC Now the voltage here is 250 volts DC Now the voltage here is 250 volts DC The voltage here is okay then we have to check on the motherboard then we have to check on the motherboard We have to measure the voltage on the ABL leg of flyback transformer We have to measure the voltage on the ABL leg of flyback transformer We have to measure the voltage on the ABL leg of flyback transformer and we adjust the screen variable resistor and we adjust the screen variable resistor and we adjust the screen variable resistor and we adjust the screen variable resistor We move the selector of the multimeter to 10 volts DC to check We move the selector of the multimeter to 10 volts DC to check We move the selector of the multimeter to 10 volts DC to check This is the ABL leg of flyback transformer This is the ABL leg of flyback transformer This is the ABL leg of flyback transformer When we adjust this variable resistor When we adjust this variable resistor the voltage at this pin must be positive and must be negative the voltage at this pin must be positive and must be negative the voltage at this pin must be positive and must be negative the voltage at this pin must be positive and must be negative Now the voltage here is only negative voltage Now the voltage here is only negative voltage Now the voltage here is only negative voltage we have to check some components nearby it we have to check some components nearby it Now the voltage here is only negative voltage Now the voltage here is only negative voltage we have to check some electronic components nearby it we have to check some electronic components nearby it we have to check some electronic components nearby it We move the selector of the multimeter to Ohm position to check them We move the selector of the multimeter to Ohm position to check them We move the selector of the multimeter to Ohm position to check them We move the selector of the multimeter to Ohm position to check them This resistor has broken we have to replace another one orange, orange, red this resistor is 3.3 kiloohms this resistor is 3.3 kiloohms this resistor is 3.3 kiloohms we have to replace another one the voltage here is okay Now the voltage on the ABL leg of flyback transformer is okay Now the voltage on the ABL leg of flyback transformer is okay Now the voltage on the ABL leg of flyback transformer is okay Now the voltage on the ABL leg of flyback transformer is okay Now the image of television is good Now the image of television is good Now the image of television is good This lesson is here to stop.
