SOURCE: Static lines one screen

as the top is ok and the bottom has this issue.
It looks like the circuit board has a bad connection to your screen.
it is not repairable by you and not an adjustment.
you need to have it repaired.
don't you miss the old wack on the side fix?

SOURCE: vertical lines across my entire screen

My 42" Samsung Plasma HDTV HP-R4252 has a 2" vertical strip of green pixels down the right side of the screen.

My 3 year warranty with Circuit City expires in Nov 2008.. so I hope I'm covered.. can't call until the morning.

Samsung said it might be a logic board problem.. but they want almost $2000 to fix. I might as well buy another TV if Circuit City can't fix it.

SOURCE: Green & red lines on screen

This is likely a bad logic board but most of the time it indicates a bad LCD panel

SOURCE: 42 inch samsung plasma tv black vertical lines

Hi, Depeending on the thickness of the lines matters. If the lines are Black and about 1-2 inches thick it may be a bad bottom buffer board or a bad panel (screen).
If the lines are thin 1/16 to 1/8 inch it is most likely a bad panel.
You can open up the set and depending on the model, see the thin board/boards running across the bottom with ribbon cables going to the panel. You may be able to attempt reseating the ribbon cables, but be careful as some retainer plugs break very easy.
If the lines are thick black and the reseating doesn't correct it you may be able to buy the coresponding buffer. Unfortunately some bottom buffers are actually part of the panel. If you are not comfortable taking it apart then call a professional but be aware labor charges start around $200 not counting parts, panels start at $600 up to over $1000
hope this helps
Thanks
Eric
