Question about Daewoo DP42SM 42 in. HD-Ready Plasma Television
I bought the lvery lastest Panasonic 42" plasma HD television only a few weeks ago. (It's still under guarantee). Today I noticed, for the first time, some light green vertical lines, extending down, perhaps 7" from the top, on the left side of the screen. I turned the TV off, and then on again, and the lines were still there. I then left the TV off for an hour - I then unplugged it, plugged it in again, and turned it on once more - and the lines had disappeared, and everything was back to normal. What caused the green lines to appear? Is there a fault with the plasma screen? Could this be related to a buffer module, Y-board, logic-main board, etc? (I'm not techncially minded with regard to plasma televisions, by the way!)
IF THE LINES ARE ON LEFT SIDE ITS THE LEFT BUFFER BOARD AND VICE VERSA THEY ARE ON THE BOTTOM OF YOUR TV HOPE THIS HELPS YOU OUT

Had the same problem. Was quoted $800 to fix. Searched the internet for 6 months and found this thread on avforums.com
Read through all the posts. Very simple fix, but you have to have some mechanical inclinations or you can cause more problems than you started with. I was up to 5 of the black lines, but decided to attempt the soldering these guys did and fixed it all for the cost of a soldering iron! Even if you decide not to attempt it, it gives you somewhere to start to tell a technician.
