Hi,

Image problems on Plasma TVs can be a result of a failure of fault in the screen buffer boards. There are several buffer boards and each controls a section of the screen: either a column so many pixels wide or a row so many pixels wide. When the buffers start to fail, it is common to see lines either from top to bottom, or from side to side or just portions of a line going halfway across ( starting with 1" black line and after some time few more lines would start appearing there ).

It could also be a problem with one of the SUS boards.

You are going to have to call in a pro to check this out. There is no way that someone over the internet can correctly diagnose the TV without being there in person and then it would likely take hours of diagnosis to narrow down the bad part.

To have this looked at is going to start at about $100 and I would guesstimate the repair cost around $500. It could be more unfortunately so it comes down to not only a technical issue but one of economics - I don't know how much the TV cost or how long you have had it but you should consider whether or not to repair or replace.

Let me know,if needed further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

If you have tried using different input devices, looked for loose contacts
in power outlet, RC Jack, cable and connectors, the TV might need service.

hi all .ive had the same problem,a thick black line down screen.sometimes it flickers from top to bottom and other permantly in view.but i have solved it.forget your ic boards and taking apart tv.have you got either a ps3 or wii connected to tv.if so unplug power lead from socket and relocate in seperate socket.make sure the lead is completely free of any other leads and you might just find this works.i think the power lead creates some sort of frequency that the tv picks up .good luck hope it works

Black line in center of screen


These black lines on the plasma screens are very fixable.  There is a dry solder joint on a circuit board at the bottom of the plasma that needs resoldered.  There are 6 or 7 "ribbons" along the bottom of the screen that correspond to vertical sections of the display, so you just follow the black vertical line down to figure out which one is faulty.  I just performed this fix successfully on my first attempt on a Gateway plasma, but it will work on most plasma's, specifically Hitachi, gateway, LG, Hyundai, & Akai. I think they may all have LG boards, my gateway did.
I can't really describe very well what to do, but I assure you it is fixable.  If anyone is near nashville, I might be able to help you out.  My email is tomp2000@juno.com.
thanks,
ST
