What part do i need for this? See a white blank strip. Are these the buffers gone bad?

Ok, so the white blank stripe is the indicator?

Failed Panel, the COF address driver which is bonded to the panel has shorted out not replaceable.

Vertical stripes or lines are never good news on any flat-screen TV, usually indicating panel or integral driver-chip failure...
Free advice--Never buy Any s/h faulty set--Unless you need its parts--if it has Any vertical lines....

Thanks, ill weigh the options. I had gotten a samsung 55ln550c on a good deal. It had pinkish vertical lines about every inch across the whole screen. I simply eliminated the screw that goes from the cover through and into the main board. Then used a larger winged bolt to screw through the sheet metal cover but too big to fit into board, causing tension and twisted until lines went away. BTW i hate 4d tv.

ah... but regular vertical lines isn't usually a panel problem. A panel problem is usually "area centric" as opposed to across the screen. As you have found, the main board can produce "whole panel visual issues" that can be recovered from.

Ok, gotcha. Now i have heard of people reattaching (fixing) tab bonds, would that he the case here? Or is it definitely shorted?

Re: Needin diagnosis of vertical lines for my potentially new project PN64E533D2F

highly unlikely that people have been successful with tab bond "remakes". You can try putting some thermal padding on one of the pads to see if it helps in terms of pressure and also heat conductivity... some people have had some success in that direction but it is usually limited and usually with lcd based screens.

Oh, yeah the lcd or plasma differences could be the factor. Im glad i asked. Anyway someone must've grabbed that tv as listing is gone.
