You should concentrate on the vertical stage since those vertical undulations that you name are a typical failure of that stage due to failures in the adjustment of some of the tendencies that the vertical takes possibly as advised by the linogonzales companion.

Ok boy friends to change vertical filters but I need the diagram to check voltages and be sure of the regulator because they changed it and I'm not sure it's the original one it has is a str30130

companion. Now that we know you use a 30130 str. options. 1 remove the flyback and the hot, place a focus of 75 / 100w of the bmas to ground. Check how much you have of bmas should be 130vcd. check the r 610 of 8.2 ohms you can even place it of 4.7 ohms. the c483 filter of 47uf / 160v. that as for the source. I hope it serves as a reference. greetings everyone. Felipe ascencio

This model also matches the jungle and the sound IC. It would be good if you had the whole diagram, but I don't know how to upload it (just photos and I just learned that). If you could indicate the steps to send it "in detail" I will gladly do it. greetings everyone. Philip ascended.

Surely you have many broken welds and the effect of image movement may be due to poor filtration in the jungle vcc, I suggest you review welds and change the capacitors associated with the power supply of the one chip

Felipe, I also don't know how to upload the diagrams, I can only upload a photo because in this new format I don't have the opportunity to add or attach a file according to the rules that you have to have 50 or more reputation points
