The board that controls the picture is bad. This board is under a metal cover . Take off the back of the TV to expose the boards. Take off the metal cover and note the numbers on the board. Go to shopjimmy's web site to obtain a repalcement. Once you have it remove the remaining screws holding the board and reinstall the new board.

SOURCE: green vertical line on the right side of screen

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.

Line accross top of the screen with flashing black and white boxes


Thin white dashes on top of screen is PERFECTLY NORMAL. It is nothing wrong with the TV, it is the broadcast. What you are seeing is the very bottom of the timecode running. It doesn't happen all of the time or all channels. It usually happens with old 4:3 commercials predating "Digital TV." This is mentioned in your Users Manual. You should be able to adjust the horizontal/vertical position in the menu settings.
