I have just noticed a light-green line which has appeared at the centre of my LCD TV screen. Is this some type of screen burn as looking at the screen up close it is much more noticeable. I never leave a still image on screen for long periods of time, although since I purchased the television last year, I have left it at it's default settings - contrast maximum but colour less than halfway. Please help. Anyone know what this could be?

Presumably the line is the complete width (or height) of the screen? - it's almost certainly the LCD panel that requires replacing!. If it's under guarantee ring them about it.

Thanks for this. Yes, it is the complete height of the screen. I know where I'll be going this weekend... Thankfully, it is still under guarantee.

I've replaced a number of LCD panels for similar faults, I've also replaced quite a lot of Plasma panels as well - but on those it's usually about an inch wide, rather than a thin line.
