Re: Horizontal Lines Samsung Plasma PN59D550C1FXZA


The plot thickens. Now a single line has returned and is working as it should in the middle of the previously blacked out zone. Is it common for the dead area to come and go. It is only one single line. I found upper and lower y buffer boards on ebay for 22 dollars shipped so I have ordered them on a gamble....

Thanks for your insight. I have seen boards used for 35 to 50 dollars but it sounds like I would be better just planning to replace TV. With a failing display will the progression of black lines eventually stop or will they continue to march down my screen?...

I finally pulled back cover off to check ribbon connectors. Cleaning and reconnecting had no effect. Over the last couple months the black lines have advanced as seen in picture. If I wanted to gamble on upper y buffer card is that all I need to change or should I also change the y main (y sustain) board as well. Thanks for your advice....

I noticed about a week ago that my TV had a thin black line about 1.5 inches from the top going across the entire screen. It has now progressed to three lines going across.

I have poked around the web and have seen some times this can be fixed by removing, cleaning ribbon cable connection. It seems other times it is the upper y buffer card. I also read that it can be the plasma screen itself failing.

I have not removed back cover yet. I was hoping to get some direction from you folks as to what may be the problem....
