Hi guys, how are you? I wanted to ask for your help, I have this tv which works perfect saved a small problem, the image appears as a shadow but orange, it is something minimal but if I increase the brightness it is like the shadow is enlarged, I suspect it is a capacitor that It is causing the fault, in the socket review all the welds around the vertical ic replace all the capacitors. Any suggestions

Hi Willy, I already solved the entire socket plate point by point. And I'm still in it. I will try to upload a photo since the problem with the cell phone is not well appreciated

See how the video filters go ... and measure voltage on the 180V flyback pin ...
Use transistors or an ICVideo on the socket plate .....
If you use transistors measure voltage in B and C of each, they should measure the same (high voltage) ...
If you use ICVideo (ADD) try another ...

Sorry that there is not uploaded an image but I took several photos and you do not get to appreciate the problem anyway, I commented that it was like a soft orange trail but annoying to the contour of the images. Check all the filters and transistors and as everything was fine I solved the tube plate again and it was perfect. I clarify that I had already reviewed before that had ruled out a possible false contact. Thank you

False welds in the socket. At first I had ruled it out if I checked the welds, but then I came back to. Review and everything was perfect. Thanks wily
