Same thing happened to my "new" Sharp lcd, I loosened the back screws just a tad and it stopped. I believe it is caused by heat from the back light and expands the LCD fluid causing it to leak down the front between the cover mask and the glass. Not an easy fix and if you have any warranty check into it....

Unfortunately, pixel thin lines are usually failures of the actual panel. If you can touch it and effect the problem, it depends on where. If it is in the middle of screen or away from the edge, you have broken connections on the TFT layer of the lcd panel.. meaning you need a new lcd panel. If you touch near the edge to effect, it is possible that the ribbon cable inside the lcd panel could be reseated to resolve. Opening the tv is one thing, but opening the lcd panel is another, its quite tricky and dust can get in between the layers. Only attempt if you have good disassembly skills and some compressed air to keep the dust out of there. The ribbon cables are very fragile and repairing by reseating is a hopeful but unlikely solution. A new lcd panel costs about as much as a new tv. Might just live with the issue or use as a tv for the kids.

check with another source or cable. you likely have a bad hdmi input, this would require a new SSB module to fix.
