my Toshiba 37" lcd tv screen has a dark curved blurry mark about 150mm
long 10 mm wide at widest part,near centre of screen.
It is only visible in certain screen colours,not pure white but an
overall off white.It is not very visible during normal watching,only
when screen is light over the area of the mark.
It is not on the surface.
Any ideas why ? Is it likely to get worse?

My Samsung has a similar-sounding shadow that shows up on darker colours
at the edge of the screen, and it is slowly getting worse. I suspect
something disturbing the backlighting.

I tried massaging the screen gently and thought it was better for a
while but it is not.

Sounds like you have smoked a couple of pixels or more


I bet it looks like soot?

I found out it is something called mura.
