Seems the LCD panel is starting to fail.

No way to really fix it. If it is under warranty then contact Samsung to get it repair or replaced.

I too have the vertical yellow line on a samsung t240, right in the center. I tapped the top of the monitor after seeing a post where someone said they were pressing on the monitor and tilting it. Sure enough the yellow line went away.

Why is there? I can only guess. Could be a bad solder connection or a bad connection on some internal cable. It could be a bad IC which functions as the controller to each pixel, but when you press on the monitor to fix it, that suggests it is a physical connection issue. It appears a whole column is not set correctly, so that will mean something to the designers.

I am going to rma this one. Samsung sent me a replacement on another monitor that failed before. This T240 is only 3.5 months old. Starting to wonder if samsung has found the limit in engineering a product for the least amount of cost!

I got the same problem on the same model and it's also 3.5 months old.
Don't know what happened.

Just send it back, as has been the advice in this thread since 2008.
