Hello!

I have a 3 year old Samsung PS50A558S1FXXU 50" Plasma that has taken to showing a red bar over the left hand side of the picture.

It was intermittent, after a week the bar is now sometimes cyan but with the image still visible through the colour.

The bar is also visible over the menus, and is on all the inputs.

The bar is 40mm wide and pushed up against the left hand side of the screen.

Unsurprisingly a firmware upgrade didn't solve the problem

I have attached some pictures

My question is:

Is the faulty part likely to be an x buffer and if so, are the x buffers part of the plasma panel, or a separate board.

and if not the x buffers, does anyone suggest which part it would be.

Many Thanks for your time.
