AmI right?
Thank you

Hello, and I don't recall seeing any component labeled "light engine" on
the schematic diagram of a television receiver ;-). I assume from your
posting that you've got a set that uses a CRT (picture tube) as a
display. A thin white horizontal line indicates a malfunction in the
vertical sweep circuits. It could be a vertical output transistor(s), a
short/open in the coil of the vertical deflection yoke or something in
the circuits comprising the vertical sweep oscillator. Also, a
component may not be defective - a broken/cold solder joint(s) can also
be the culprit. Sincerely,
