Question about Computers & Internet
The fault looks like white lines horizontally along the screen. These are the retrace lines that become visible due to absence of proper screen/grid voltage. You will need to open the monitor only if you are familiar with power electronics, a bit of experince is important as the stages are delicate and contains high voltage. If not take help, check for faulty capacitor or low value of resistors in the screen/grid sections of the crt. Couple across parallel to the suspected capacitor to confirm and change. Use a meter to see the voltage across faulty resistors. In some cases reducing the screen potentiometer ( onthe Line output transformer)can solve the faulty. Hope you try. Good day
