On the KDFE55A20 this sounds like a bad Q-Box. I would get an estimate from a Sony authorized servicer as this part may be quite expensive. On the 55A10 model this may be the B-Block and is also quite expensive. Getting an on-sit estimate would be the first step I suggest. Again go with an authorized Sony servicer. Call Sony or go to Sony.com for customer service. Good Luck

The tv is shot. This occurs when pixels on the top row of the screen break, which blocks current from moving through the rest of the pixels in that column. But don't worry this problem is common and is covered in your tv's warranty.

Bad/Going Bad/Will go horribly bad TCON board (small circuit board sitting at the top of the panel in the back).
Most likely, the whole panel will need to be replaced in order to rectify the issue.

This is caused by a failure of the optical block of your TV. The only way to fix the issue is to replace the whole optical block which is very expensive ($1000+) and time consuming (need to take whole TV apart to replace the part).
The optical block in your model had inherent issues and there is currently a class action lawsuit pending against Sony for this issue. Up to date information reguarding the lawsuit can be found here: http://www.sonya20tvclassaction.com/main/home.sfx
