I had a service rep come out and check my set (i had the extended warranty)
I have the long turn on (caps issue) which he confirmed.
I also have the vertical lines as well a dark splotch on the right side of the screen. He said the lines and the splotch are due to the panel going bad.
The lines go away, but the splotch stays the entire time.
Not sure what you mean by Tab Bond related.
I found the following which shows a video.. the video looks like nothing I have, but from other descriptions of the tab bonding, it could be related.
