Good evening, these chassis are really complicated to repair sometimes, especially in the vertical stage, but if it is a SLIM TV, you must always renew the electrolytic capacitors of this stage. And well in addition to these ICs are often counterfeit, or very low quality, this with good luck. Only two wires should go to the YUGO, there is nothing going to the ground that I know of, two are for the Horizontal (RED / BLUE) Vertical (GREEN / YELLOW)
A white wire, no idea what it means, besides it says that it is earth ... The TRC does have to have a yes or yes connection to ground, but the color seems to me to be always black, well but it is not a rule for Chinese chassis it seems to me .... In one of those if you detail the repair by uploading some photos of what you are doing ...
sorry the cable was black that goes to the wire that goes to the cross screen from corner to corner, when I arm it again I burn the diode vd564 that reaches the shopper transformer -13v and the ic measures me short the question is that it would not harm other component
good thanks for the help, the solution was that I insulated the ic and put a replacement ic LA78040 and it works only that the TV menu is a little blue does not highlight the colors much thanks a question the temperature is normal in the decipator of the ic?
EN 21 INCHES THE BLUE COLOR DOES NOT HAVE ANYTHING THAT REAL BROTHER THANKS FOR THE CONTRIBUTION
