SOURCE: thin vertical red line
This maybe the symptom of a bad Panel. One Vertically This line is 99% bad panel. Call your warranty provider or SONY tech support if purchased under 2 years.

What you're describing is usually the result of an improperly seated connector. With the power disconnected, open the tv and locate any connectors between the LCD screen and the driver circuit board. Unplug them, and reconnect it assuring it's properly and firmly seated. Be careful when handling these cables as they tend to be quite fragile... take your time.

In most cases is the screen is covered with vertical lines all the way accross the screen then the T-Con module is at fault. The t-con board is replaceable without having to replace the entire LCD panel which would usually make it cheaper than replacing the TV. The part number I come up with is 1-857-213-11. Please take a moment to rate my answer. Thanks...

Most of the time the " T-Con" board is the cause. On a lot the Sony models, this board is not replaceable without replacing the LCD Panel. Sony has been making more of them available but you would need to check with Sony's Parts Department if it is available for your Model.
I hope this helps,

No solution here.
I have the same issue... A vertical magenta line, about 2 pixels wide, appeared about 1" from the left side of my 52" LNT5265FX/XXA. Of course, this appeared after the 1 year warranty... For me it started showing up about 22 months from purchase date. It goes away when the TV warms up after about 30 minutes or so. Sucks that such an expensive product has developed this issue w/in 2 years.
Hi
It could be a power supply problem or an inverter board problem or something internal having to do with the backlighting of the unit. remove the inverter, and look at the back side and you will see a hot spot, now on the other side of that hot spot, re-solder the service mounted components and that should take care of your problem.
Please get back to us if you have further query else please accept the suggestion.
