Good afternoon first of all, a warm greeting I have the following problem with this phillips chassis L03.1L the TV came off the source did not oscillate replace the tea1506t the normal starting source with 115V that normal in this chassis although it indicates that they are 95V, when giving the ignition order gave the typical fault of the colored lines and it came out somewhat closed above which changed the C2465 10uF x 160V which was devalued. When starting again the TV is not seen, when it shines through the screem, delay lines come out and there is no light, when installing the original C2465 the vertical fault comes out and there is rain. I have replaced C2465 10uFx160V, C2446 470uFx16V, C2460 68nFx250V

Hello Friend. solved the crystalline welds that you see on the plate, and check the filters of the vertical section can be some underrated and that filter of 10ufx250volt. It can be bad. Cheers

Amigo replaces the ceramic capacitor that is between the vertical and the fly-back.

Thank you for your answers but I have already tried several countesses from various manufacturers of 10uf x160V, and I have re-shielded the c2460 or ceramic capacitor that the friend comments on 68nf, 80nf and I have also resosolded this whole section, the same result being the same

The solution was to change transistor 7463 (C546B)
