    Thanks Mr Tevs. Very clever to be able to do these repairs even though you don't have the right component available. Thanks for the tip about the optocouplers too. Best wishes.

      Engineer doesn’t do this kind of alteration. Engineer always find the actual source of problems and rectify it with proper solution. This guy just altered the circuit with non professional substitute which is not long term and proper solution. He is just another repair guy.

    I think changing the fuse with resistor is not safe practice. Safety fuse is a primary protection when there is short in your circuit. Changing it with resistor just limits the current in your bridge rectifier due to your bulk capacitor inrush current. So it is better to keep the fuse untouched when doing test to safely prevent damage…. Nice troubleshooting tips though, thanks for the video.

    Nice video, always tell people to subscribe to your channel because people dont know subscription is free. Thats the reason most people dont subscribe.
    As for the right optocoupler to connect, i usually trace pin 4 back to the PWM IC pad. Ive never tried looking out for 431.
    Im still wondering why you always use the 220ohms 20watts resistor. Whats the effects if i dont use it? Is the fuse not means to blow out when theres a wrong connection? Why put resistor that will not blow? Or will the resistor blow?
    Once again thanks for your video i now know how to modify power supply.
    Though i tried it on one power that has a different pwm ic about 16 or 18 pins

    Amigo puedo hacerle una pregunta espero me ayude. Los transistores 30F124 o los RJP63K2 se puede medir con tester en la escala de diodos. Estos dan una lectura de un lado y si volteas las pinzas no da lectura en pata 2 y 3 y al activarlo mide un valor más bajo estaría bien el transistor si da un valor en tester. Gracias
