Tv 50in LG plasma got a very thin blue line down the left hand side from the top 2 bottom of the screen
SOURCE: blue haze on my plasma screen
The driver boards on that side of the set need to be replaced, about $400 for parts.
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

IF LCD TV has vertical lines try cleaning T-con board to lcd panel cable or replaced t-con board

There is no color wheel or lamp in a plasma TV.
The problem is most likely the lower buffer " E ". It controls the right side of the screen. Worse case, it could be the Logic Board. A Service Manual for you TV will have the part number for replacement. The manual will also give you procedures on how to replace the part yourself. The service Manual for your TV can be found over the internet for less than $20. This is the best do it yourself manual you need for repairs on your TV. :)
