Good afternoon, Colleagues I have a mystery with a St-2107s daewooplus TV which they brought to the workshop because it did not turn on, when I checked it, I realized that the screen was split at the height of the yoke. Then place a 19-inch screen. And the TV looked perfect and without novelty. The problem happens after a month, the client tells me that the TV does not turn on, when I uncover it immediately I notice that the screen is broken again, but this time it broke and took off with the yoke stuck. I need to know why this phenomenon happened, bone, because the screen broke again.

Problems in the vertical stage due to the absence of one of the working voltages of the vertical IC. Before placing another CRT as a precaution, change the vertical IC and filtering of the +15 and -15 sources that feed it, in addition to checking the state of its components and welds in the stage. - .. http://www.tecnicosaurios.com/foro/viewtopic.php?f=3&t=33415

Hello, do not rule out the possibility that the high voltage cable is leaking and it causes such failure. Download by unhooking the yoke.
