Samsung 42" Plasma-SPN4235 screen problem

I have a Samsung Plasma TV Model# SPN4235, 2 months ago a black vertical line appeared (no video info) at about the centre of the screen. Replaced the Logic board and the G Buffer borard that corresponds to that particular area of the Panel and the line is still there. Any ideas what other board I need to replace?

Hi have a samsung 42 inch plasma, all of a sudden it has a band 20cm wide of dotted lines going across the whole screen, some channels or when playstation in use the band gets wider, does not seem to...


if the band is horizontal your tv has bad y-buffer board. Usually there are 2 buffer boards- top and bottom. if the problem is in the top half of the screen replace the top board, otherwise replace bottom board.
but better to replace both a the same time.

if the tv has a vertical lines from top to bottom it may have bad plasma panel and can be considered as not economical to repair.

Mu samsung has a red vertical line through the picture


Hello,

IF YOU HAVE A SOLID BLACK LINE RUNNING VERTICALLY THEN YOU HAVE A FAULTY MATRIX INVERTER. IF CENTRAL THE MAIN VERTICAL INVERTER NEEDS CHANGED. LEFT = LEFT VERTICAL INVERTER RIGHT=RIGHT.........

ANOTHER WAY TO GET THIS FAULT IS WORN OR DAMAGED RIBBON/PLASTIC GOING FROM THE SCREEN MATRIX TO THE INVERTER

Hope this help......

Samsung 42" Plasma -Black vertical line when turned on.


It sounds like an Intergrated Circuit (IC) has fried. Even on a good day, this is not something you can attack at home. As a tech (and as an owner of that model samsung), I'd need a map & tools to know what's going on. Your best bet in this situation is to contact Samsung and let them recommend an authorized service center in your area. Sorry I can't be of more help, but this is a rather serious problem.
