Re: Sony 52" Bravia LCD with vertical black "pixelated"...
If it ic a real thin line, there is only 1 thing that can cause that,,,bad panel, if your under warinty, thats a good thing-(verry expensive part--about the cost of tv) if your not under warinty, and it is less than 2 years old, call sony and explain what it is doing, and that you would hope that there TV's would last longer than that, sometimes they will cover the part

I got colored black and horizontal lines on mine today and during the .... Sony Bravia KDL-46VL130, ca 2007 - We have a greenvertical line on ...
LOD (lines of death) are a known service issue with the Sony bravia line of TV's contact Sony and cross your fingers. Wish I had better news for you. I had a 52w4100 and Sony arranged me with a service center to get it taken care of.
Unless it is spot on dead center of the set, you need to replace the LCD panel. In these models, the suspected TCON (time control) board might do the trick, but I've yet to have success with that board fixing a vertical line issue.
Hopefully you are still under manufacturer's warranty or have some kind of extended warranty, 'cause the price of that panel exceeds $1,500.00.
You could give a shout to Sony customer relations in the event you don't have a way to get the part paid for. Sony may ask that you pay for an estimate, in return for covering the part for you.
I'm afraid, its problem of LCD Panel (screen). LCD Panel replacement is only solution for this problem and will cost you 70% of TV price, please contact nearest Sony service center for LCD Panel replacement.
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.
Thats a pixel data problem, there's no data being sent to that row of pixels so they don't change color. This is a pixel address registry (PAR) issue and the PAR circuits need to be serviced its usually due to open or shorted SMT components on the PAR circuits. PAR also sends data, voltage, and control to each pixel, the green line you see are pixels that have voltage but because there's no data sent too them their all green because there's no control. If the pixels have voltage but no data or control they show up as green red, blue, yellow, or whit line vertically down the LCD panel. The vertical-horizontal section of PAR are controlled by 16 to 32 bit micro-controllers which may need replacing. If its under warranty take it back if not have your local repair center fix the tv for you...
You are going to find it is a LCD panel problem. I am sure that they will take care of you. But also realize that this could have happen to any brand of LCD panel and you will probably not have any other panel issues once it is fixed.
I feel your pain,
First, HORIZONTAL CENTER. 1) Press MENU. 2) Scroll to SETTINGS. 3) Scroll to SCREEN. 4) Go to HORIZONTAL CENTER. Move the picture to the right. Hopefully, the line will go away. Otherwise, there is a problem with the pixels or the signal processor. Call 1-800-222-SONY. Or, http://eservice.sony.com. Have a high-limit credit card handy for out of warranty repairs. Sorry about that.
