Sounds like your LCD panel is failinf and will need to be replaced it is going to be costly around 1500

This is common problem on this tv, picture tube is bad. Blue and green is more % bad.
Thank you

Replace Y drive should solve the problem.

the vertical blue lines indicate some interference from other electronic gadgets near your tv. it started showing up on my sony grand wega when i installed my wireless modem. i almost ordered a new rear projection lamp costing over $100 but decided to experiment. i first moved my desk computer farther away from the tv then isolated the wireless modem router by placing it inside a small glass - the vertical blue lines became lighter in color so i dedided to find another small glass that fit inside the first glass container then put the router in the double glass - no more blue lines and my wireless modem router still works.
do some deductive thinking to figure out what's messing up your tv and isolate the interference.
good luck!

This is a common problem with LCD screens. It is pixel line damage and the screen is permanently damaged and is not repairable. It will probably get worse. The only answer is to replace it

You have a completely different problem. The screen voltage for the blue picture tube is slightly too high on your set. This will put fine lines in the background of the picture, called retrace lines. This is very common and easy to correct. Remove the front speaker cover and the access panel behind it. Look inside and you will see a black box with six controls, each control having a little white glue on it. This is the Focus/Screen block. Three controls are labeled Focus and three are labeled Screen. The screen control in the center is for green but I am not sure if the screen control on the left or right is for blue for your model. With the TV on, set it to VIDEO 1 but do not connect anything to the VIDEO 1 jacks. This will produce a pure dark picture, showing any faint lines in the background. Choose one of the screen controls and increase (turn clockwise) it slightly. If the blue lines do not get brighter it means you are turning the red screen control, so put it back where it was and choose the other screen control. When you find the blue screen control, decrease (turn counter-clockwise) it until just when the blue lines are gone. If you want you can check that the red and green screen controls are set to just below the point where their faint lines are visible. When done, replace the panels and your picture will be back to perfect.

You'll get this abnormality some times due to the signal if you're watching regular analog picture and you have your TV set on full screen, the TV will stretch the picture and you will see more defects than if you're watching it on normal picture. But if you are seeing the same problem when watching HD picture it needs to be serviced try this link I found: http://www.moniserv.com/doc/lcdtv.html

it's called retrace lines ,your screens are set to high or focus block assy which has the screen adjustments on it also is faulty
