Excuse me as I told you, be electronic. But I'm not a TV technician. As I measure that abl I know that it has to do with luminance. How much should you measure me? the tv If you change the channels and hear it perfectly, you cannot see the filament on.
If filament does not turn on you will NOT see anything at all. Focus the repair on that side. That if the light is turned off (in the dark) it is not possible to see the filament on. Inside the tube. Where that square plate goes. What is chroma. It has a socket welded on that plate, it joins the plate with the pins of the tube. On the pins of the Zocalo, see for sure it tells you H, which is filamentous. It has 2 one going to mass ditecto. And the other receives the tension of the flyback. That pin or some open or printed component may be desoldered. Follow the path if you know electronics. It will take you to the flyback.
Something else to contribute and there is no other fault.
That the flyback does not deliver tension. You can get it out of the flyback core. So feed filament without changing flyback.
There is nothing else to do.
Well for now I have nothing left but to follow his instructions. and I will be informing Mr. Luis. Thanks in advance again. you are grateful
