I'm afraid, its problem of LCD Panel (screen).
LCD Panel replacement is only solution for this problem and will cost you 70% of TV price, please contact nearest Sony service center for LCD Panel replacement.

SOURCE: verticle lines for picture
You need to describe these lines better. Are they moving or stationary? Are they very fine lines with sharp edges or are they more like bands with soft edges? How many lines do you see, and how wide are they (compared to the screen width)?
Fine lines that are stationary: defect in the electronics causing a vertical row of pixels to be dead or stuck. Can only be fixed by replacing major parts.
Broad lines with soft edges that move: could be electrical "hum" interference. Make sure you are using a grounded (3-pin) power plug, and that the outlet is properly wired. (Take the TV to a another location and see if the problem goes away).
Make sure you don't have fluorescent light fixtures nearby--they can interfere with the picture if the bulbs or ballast is defective. Could mean tecon board or display is bad which means replacing both in a sony if they are bad i recomend buying a new tv because it is not cost effective to replace these.

it may be the display panel especially if the line is black.
Some tests are needed and maybe a board swapped etc but if it turns out to be the Panel the part costs more than the set did when new===fatal.

SOURCE: my sony Bravia kdl-46v5500 screen has colored lines on the left side then half the screen flicks black then the same left half side of the screen stays black then will go back to normal and then go
These sets use for the most part two boards--each drives the screen on one side---also possible as suggested here the problem is inside the panel or where it connects to these boards--if inside the panel (the entire front screen unit) it is fatal as it cannot be got at and the display costs more than the set did new.
