Just be be clear, yes, the back light (cold cathode type) is clearly working. My point was that the electrolytic capacitors for the high voltage supply that this uses may also need replacing. From the comments, the power supply circuitry appears to be on the same board where you have already replaced one of the capacitors.
As Ken says, the blue line is indeed likely a panel connection fault. An LCD panel like this is one big matrix of pixels.
