I am a Sharp Servicing Technician. You posted this before. Ive got the same model TV as you do LC46D62U. I think the line you are experiencing is simply the broadcast. I notice it on some HD shows that broadcast the side bars. (Always on the Ellen Degeneres Show). Ive taken some picture.

1) Here's the line on the left that i experience


2) Later on in the broadcast, it goes away.


One way to check if its a TV problem or not. When the line shows up again, hit the MENU button on the remote. If the line appears to be "behind" the menu, then it is simply the broadcast.


If the line appears to be "on top" of the menu or shows right through the menu, then it is a TV problem.

Im thinking the reason it takes hours for hte line to appear is because it only shows up on certain shows or certain HD broadcasts.

the flashing light often shows malfunction ,check the wire connection of your devices something must be wrong .the surge protector you have is for overpower or low voltage too?Ask your neigbours if they have shame problems
