    Samsung PN58A550S1FXZA Vertical Line

    I have a Samsung PN58A550S1FXZA and a single skinny line has appeared in the bottom right that goes about halfway up the screen. The line is usually green but sometimes is not green or not present based on the background. The green line is most noticeable on blue and red backgrounds. I attached a photo

    I have confirmed it is present in multiple inputs and have tried unplugging the tv and then plugging it back in.

    I am a competent DIYer and would love any advice on what could need fixed or is wrong.

    Thanks in advance,
    Chris

      I believe it's one of three things in order of likelihood:
      - The address board that runs along the bottom of the panel in the vicinity of the line is bad.
      - The connector to the address board is loose or dirty.
      - The panel (chip on flexible ribbon cable between the panel and address board) is bad <-- not repairable

          Sorry bit of a newb, when you say address board do you mean the Y-buffer board that controls the bottom half the tv?

          It is my understanding that the Y buffer board is cheap and easy to repair. Playing with the connector sounds like the easier first step but i'll order one of those boards.

          The ones on eBay are all used - i dont supposed that is a big deal, right?

          Thanks,
          Chris

              No: "The address board that runs along the bottom of the panel in the vicinity of the line is bad".

              Edit: It might be called "E-buffer", "F-Buffer", or "G-Buffer". I'm not familiar with this particular Samsung. If they're installed in alphabetical order, it's most likely the G-buffer. It's best to get a schematic or open the TV to confirm: http://www.shopjimmy.com/catalogsear...ZA+&restrictBy[master+part+type]=Buffer+Board

                  Thanks. After some additional conversations and research I think the plasma is going bad. Everyone said that a think line that is not across the screen is the plasma. If it was a thicker longer line that it could be a buffer.

                  Is this consistent with your experiences?

                  Thanks,
