This may not be the problem but its worth a try:
The plasma display screen is made of a matrix of elements connected to cables along the side and top. On your unit, some of these many, tiny connections are making contact intermittantly thus losing the elements in that area. These contacts are held in place with just pressure and if that is disturbed, you lose that line of elements. Try squeezing the cabinet of the TV on the outside at the top in the area of the loss and see if that makes a difference. May have to go inside and see if the contact assembly is disturbed or warped or something.

SOURCE: Horizontal Lines On Screen

horizontal lines = horizontal sync off . mitsbishi always seemed to have this problem .. on the older sets I would take the back off and inside deep on the board i would adjust a pot and sync it right .... and never had a recall, maybe your newer model has this too .. this little control,

but its a horizontal sync problem.

if no change the horizontal processing ic.

SOURCE: Sony KF50WE610 Vertical Blue Lines Across Screen

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!
