Hi, I have a model noblex TV, it does not turn on, it has no standby mode, when it opened it, the ic tn6g04-e had blown it, together with two zener diodes, one of 6 volt and another of 18 volt, replace the burned resistors and tried the others , all good and I tested the other diodes and everything good, unlink the horizontal transistor I put a spotlight and it also does not replace the regulator se140, check voltage pin 1, 300 v pin 4; 17 v pin 2 voltage does not arrive supposedly has to reach 6 volt check everything related to that track and there is nothing burned I choose it and it is ok, the voltages do not go to the secondary if someone can give me a hand is appreciated

Apart from testing the resistance mentioned by ray_yoshua, it controls the transistor Q601 that is related to the FB of the IC that you changed. If there are no voltages at the output it is clear that the circuit is not oscillating ..

hello sorry that late in answering, this TV does not bring the q601 what I need is to replace the 220k r, and the friend ray-yoshua you refer to the regulator 140? that regulator does not work because there is no voltage, just the pin 2 of ic 601 is missing thanks for answering
