I bumped my screen by accident recently and now have a similar problem (multiple vertical and horizontal thin lines). I was told that the screen is now bad and probably cannot be repaired. The cost of replacement is more than the cost of a new set. Sorry, but that may not be the answer that you are looking for.

Warranty still alive?
Hope so; the problem could be an expensive one.
The screen appearance is controlled by allowing light from a backlight through by turning pixels off and on.
This switching is done by a matrix that turns on vertical and horizontal pixels of the right shade at the right time to produce the image you see.
One of the control elements for the vertical that controls the transmission of green light from the backlight, has died (no longer switching off and on when told) and these are normally a part of the LCD screen assembly itself and not easily replaceable.
I would be talking to Sharp - this shouldn't happen in 6-7 months of use.

You must contact a svc co. This is a upper or lower buffer board problem and possibly a control board. Nothing you have done wrong, it just happened.

I think your TV have a trouble inside lcd panel
the controller board contains driver IC. Deffective driver IC can cause of line display.
Three reasons why one vertical line accross screen can happen in LCD;
1.The missing signal from the controller IC to
2. LCD driver IC itself defective
3. Dry contact in the tape carrier package.
Use masking or electrical tape to mark it where the line was located. press it if the line back to normal but when release your hand came back i think it was intermittent. Open the LCD panel
Place the rubber on the top of TCP
Gently close back the top casing
