IF YOU HAVE A SOLID BLACK LINE RUNNING VERTICALLY THEN YOU HAVE A FAULTY MATRIX INVERTER. IF CENTRAL THE MAIN VERTICAL INVERTER NEEDS CHANGED. LEFT = LEFT VERTICAL INVERTER RIGHT=RIGHT.........
ANOTHER WAY TO GET THIS FAULT IS WORN OR DAMAGED RIBBON/PLASTIC GOING FROM THE SCREEN MATRIX TO THE INVERTER
Hope this help......

This is typically your color projection drives going out. Soo the picture will go black and white, and the hum will prosist.
It is cheaper to replace the set than it is to replace the Red, Green, and Blue drives; and then have the set re-aligned.
Unless you have a family TV repair guy or know one that loves food! :)
