Comment on the voltage you have in the tansformed driver or in the collector of the transistor driver both in stanby and when giving the ignition order, for this test first put the tip of the tester in the place to be tested and then turn on the TV. comment that voltage .... greetings
Friend, I think you inverted the voltage values that you placed in your question because if you say that the TV turns on and presents the vertical fault line then the voltje of + B is 111 and the main filter is 159 volts. I would say that FR301 is open.
Amigo ELECTRONIC you are right I have already corrected my error with the data, thank you very much. Francisco friend in stanby 106v and lit 110v
Already change the fr301 0.05 did not have an equal only had a 0.22 ohm I do not know if you can leave with this or it would bring some kind of problem. The image opened 26v were restored. I only have a few delay lines at the top
friend. if you have not changed filters that indicate those lines it is by devaluated filter
Friend, then I try to measure it but I don't get a result according to the diagram, the fr301 is 0.05 / 0.5w but the tester doesn't give me any value
If it doesn't give you any results, it's open, change it to a 1 ohm if you don't have an equal.
I changed it to a 0.22 ohm and it has already opened the screen, it only has some delay lines at the top.
The fault is now solved friend change the capacitors of the vertical and ready, value the solution and close the post, greetings!
