Hello Friend. check the 10ufx250volt filter. Or it can be 22ufx250volt. and if the failure persists check the abl. and the socket can have loose welds on the pins.
friend. The tendency that ic.vertical la7841 should have is pin 1- gnd. pin 2- 13.8volt. pin 3- 26.2volt. pin 4- 2.4volt. pin 5- 2.4volt. pin 6-25.7volt. pin 7 - 2.3volt. This is because you indicate that TV. does not open and the above is because you indicate that you have delay lines
friend. Remember that you have to change the filters that are related to the ic. vert.
the 22uf x250v filter is fine 200v of the tube plate are those that are not there are the red out green out and blu out pulses that leave the jungle that would have to measure red out = 2.49, green out = 2.13 blu out = 2.3 give me, red out = 0 blu out = 0 green out = 0, abl = 4.6, and change the ci vert the voltages in ci vert are: pin 1 = gnd
pin2 = 18v pin3 = 27v pin4 = 2.5 pin5 = 2.5v pin6 = 27.2v pin7 = 1.6v
friend. You have not done all that is indicated, I told you about the socket, you solved, the plate about the abl, and the ic.vertical is a bit well
