It suddenly lost its picture; it's displaying vertical lines on the right side of the screen. The sound is still working fine.

Press menu button on the TV if the on screen display is also distorted or no pic the TV is definetely defective. You can try unpluuging from wall for about 15 minutes and see if reset helps if not problem is either main p.c.b , LCD panel , LVDS cable or Power supply board. and would require service. most likely problem would be bad connection at or defective LVDS cable that connects main p.c.b to Panel (cheapest fix) or defective main p.c.b. If it is the panel it would probably not be worth repairing and you may want to sell as is on ebay.

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.

Bad news any lines like that mean the communication between the pixels and drivers is broken.
the glue has come loose.
Most will say it cannot be fixed
but there are tricks. it requires the panel to be taken apart.
Only a real tech can fix it.
Warranty time.

This is a screen address failure from part of the matrix addressing. This can be caused by fair number of types of faults to cause a missing part of the addressing. You will not be able to fix this yourself.
Find out who the authorised local Samsung service is for your area. They will be able to give you an estimate.

Had this same issue on right side of 52" about 1 inch from side but had 3 vertical lines that disappeared after 40 minutes. Have Samsung LNT5265FX/XXA and about 16 months old. LCD Panel itself had to be replaced to fix it, fortunately had extended service plan
