I`m watching the screen and this BLUE about 3 inch wide line pops out on the screen from top to bottom. Kind of like the pixels went bad.. I got scared, started switching channels but that line was just staying there. I turned off the tv. turned it back on and still the line. Figure maybe its the cable.. Turn on the dvd the line is here..!! I start freaking out, since my tv is brand new!. I come up to the tv, and touch the spot of the screen where the line showed up and it just dissapears. Kind of like a magic touch thing. I`ve been watching tv for a day now and it hasn't come back. Was wondering if its something i should worry about? OR is it something that happenes in plasmas? The line looked like somebody ADDED BLUE's to that part of screen... should i call Panasonic? Thanks a lot guys!
I had a similar problem, except I had a GREEN vertical line, about 3" wide, just right of center. This problem showed itself the first day I turned it on. I called Panasonic CS, they were very helpful and we scheduled a service call to look at / fix the problem. The day before the service call, the line went away!!
I called the technician and he wanted to come look at it anyways. He mentioned it might be a loose or not completely seated cable/ribbon on one of the circuit boards. He came and replaced two of the three circuit boards (since the band had appeared between two of the boards and couldnt tell which board might have been "bad").
Well, he then went to power the TV back up and guess what... it wouldnt turn on. He couldnt figure out why it wouldnt power up and was concerned for another problem. His solution: take the TV back to the shop, where they supposedly discovered a power supply problem.
That was three days ago and I havent got my TV back (though I'm suppose to get it back this afternoon).
Moral of the story, IMHO... if the band has gone away, dont have a tech out to take your TV apart.
