tv trc sankey ph08kx-n22, burning diode vd 564
The components mentioned above correspond to the negative supply of the vertical IC, according to the diagram is the STV9302B but it can also go, the UTC78040 (It is clarified in the diagram) that any of the integrated ones that are replacements can be used. Is the polarity of the components well fixed when renovating them? Some vertical ICs are falsified, I don't know if you know the place where I bought it well ... But the recommendation whenever the vertical is in that state is to thoroughly review the stage in search of shorts, such as SLIM TVs the majority
Remove the flyback to rule out short, I measured the ohm and none measures less than 1.2 kohm, what else should I do because in truth this case if I have thoughtful, I hope they continue to help me to solve the problem and even more to enrich my learning
short I mean less than 1k with respect to gnd. before putting vertical you must restore those -14v. but I tell you that if you put a black tip on the ground and a red tip on the diode that burns and there is a resistance less than 1k, then there is a short component
Hello friends and thanks. I was checking and it was the chassis of the vertical that was short with the heat sink to which it is close and for this reason caused the short, then I insulated the bases of the heatsink that were connected to the current and ready it worked, I thank you for your great Help because I was eating my brain, thanks.
Well I change the capacitors that are serca for others of equal denomination in total 5, take out the flyback to get out of doubt and measure where the diode vd 564 (terminals) is connected and it marks me continuity not being the diode or the capacitor c562 intact, What else can I do, any other clues? Thank you
Remove or weld the vertical IC and fashion again.
Remove the yoke and fashion.
Continuity refers to direct short 0 ohm or how much. I commented result
