My Samsung has developed this 'fault':

That's taken from elsewhere, but it's the same problem - except it's on the right. Only noticeable during sporting events (due to the constant panning & green background).

Anyone know what it's all about/what's causing it? I'm not sure I want to pay £100 for an engineer, as it doesn't effect most viewing. I'd rather put the money towards a new TV down the road.

Most likely cause is the screen.

I had same problem with my Sony 32" and thought its problem with TV but then my sky+ PVR2 had recording problem and it was replaced with brand new one PVR3, since then i don't have this problem anymore, so maybe its same with you so try checking different sky box if you can and see if problem is still there.

I have a similar fault on my 32 Samsung. It is a green fluorescent vertical bar about 4" wide that runs the length of the screen. It is only really visible when a 'dark' or black scene is showing. I have a sneaking suspicion that my Sky+ box may have something to do with it but haven't tested this yet

This is a problem I made a post about a couple months back but can't seem to find it now. My vertical line was on the right side too but later noticed a line on the left side. Apparently its the LCD equivalent of screen burn, called Image Retention. Its caused by viewing 4:3 programmes a lot on a screen designed for wide screen.
The good news is this, since I found out what was causing it I've been using the zoom screen mode when watching 4:3 stuff. I've noticed that over the last few weeks the line has started to fade and is now only slightly visible in certain conditions.
Hopefully the line will totally disappear soon.
Hope this helps...

my 40" samsung had a line of pixels that would go pink, had the entire screen replaced and haven't had the problem since

Have you a different source you could connect to the set?

I'm wondering if it isn't crosstalk from another device or channel. i.e. what you're seeing is the sync pulse from something bleeding through. Does it shift position at all?

That was one of my first thoughts when I first discovered my own problem. I disconnected every external source but still had the lines.
Worth giving it a go though... Just in case...
