Good afternoon, what is the chassis that carries the TV? When this fault appears, what are the voltage levels of the video voltages 180 V / 200 V. ... How tall is Screen?

At the moment the image turns white: does the sound remain? Is the symptom repeated by the auxiliary AV input? First, when the defect arises, manipulate the card or give light strokes with some insulating material, in different areas of the card, especially the jungle IC. Monitor the voltage of 180v before and during the fault and observe if there are changes. It is not necessary to verify again the state of the welds, especially the voltage regulating ICs that feed the jungle IC.

For the moment, measure the tensions of the main filter - of + b - chroma-scrin -ABL. In both states. That is when it turns on and looks good and when the fault manifests. Maybe you notice a change in some and you find the problem. We await your input including the chassis. As I put the colleague.

And well if the customer removes it so we will do it. Too bad he doesn't continue investigating and with the solution. But that tensions are good can not be. Otherwise I would not have such a failure. Once something like this happened to me and it was the + b diode. It was cut right where the pin comes out. I discovered it unintentionally in the dark. Because it made a spark. And the tv was perfect. I already gave him change until the flyback. When it turns white press the scrin and see if it improves. Or if it looks good, throw a little Asia out of it. The other is that you tap or twist the plate. And see if it's false contact

Tell the client that it will not last and that you are not responsible.
Rate the contributions at your discretion. But the problem was not resolved. I think you should not close the subject.
