what do you mean high voltage lines? to get help you need to be a bit more explicit. for example i GUESS that you are dealing with CRT style monitor. I also guess that what you see is brighter than usual image that is not distorted other than few bright skewed lines near top side of the CRT. sometimes they are spaced further apart and go across entire screen. see https://humphreykimathi.blogspot.ca/2011/02/causes-of-retrace-lines-on-crt.html

you mean you're seeing retrace lines? you may have a bad connection on one of the tube's cathodes, have a shorted video driver transistor, or have a cathode shorted to the grid internally in the tube. if they're white retrace lines, then you might have no power to the driver transistors at all, or are missing the blanking pulse.
