Hello people, I saw that this fault has happened to many but nobody found the TV working well but it tears the image like a saw in a horizontal direction as if it would be out of frequency and I do not give what causes the failure, if someone step and give me a hand thank you thank you greetings

For a better appreciation of the problem, upload a photo. The symptom is repeated by the auxiliary Audio-Video input. After checking the + B filters and the line rectifier source .... His report directs us primarily to the stage of Synchronism separator, horizontal oscillation, AFC and horizontal driver. Even AGC. Verify the good condition of the components in those sectors.

He still does not comment on the initial test of the status check or changes of the capacitors of the sources. (Primary and Secondary).
