I dont know if any of you Polo 25 folks have solved the "vertical black/white bars" problem on the left or right side of the screen but in this case, it was the replacement flyback!
After I resoldered a working original back in the chassis the lines disappeared. Most likely cause is the internal diodes were weak or the capacitor (although the schematic shows no internal capacitor).
Then I researched this problem and in EVERY POST I READ this problem occurred after a capkit/new flyback install.
However, Im also certain this can happen to the original flybacks as well I just havent heard about it yet.
