Had the same problem. Was quoted $800 to fix. Searched the internet for 6 months and found this thread on avforums.com Read through all the posts. Very simple fix, but you have to have some mechanical inclinations or you can cause more problems than you started with. I was up to 5 of the black lines, but decided to attempt the soldering these guys did and fixed it all for the cost of a soldering iron! Even if you decide not to attempt it, it gives you somewhere to start to tell a technician.

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.

I wanted to share my solution to this problem. Not only is it an easy fix (aside from taking the tv apart) but it also explains some of the strange methods I've read that have worked, such as taking out padding from behind the boards or putting a magazine under one side and even tapping on the tv for a temporary fix.
Granted its only been a few days of it working but I tell you this....It's not done the half black screen once! And trust me when I say it was doing it constantly.
Ok so first off the problem definitely lies in the upper/lower buffer boards. On the model mentioned by the OP (same model I have) it's located on the same side as the power button (right side when you are looking at the tv).
Ok so you've got the tv openned face down on a non static surface. Btw I was shocked at how many youtube videos I found of ppl working on their tvs while its laid flat on their sofas!
When you are looking into it you will see on one side there are two vertical boards hooked up to another board more towards the center. These two boards are your upper and lower boards that provide the upper and lower picture. The problem I was having was in the lower section of the tv going black so obviously that corresponded to the lower board. (They are labelled upper and lower if you look closely)
So here is what I did:
I noticed the lower board was not sitting flush so I unscrewed the one screw on the bottom and noticed how much of a gap was in the screw hole. The problem was it was screwed down in such a way that one of the connections going to the main board was not making it's proper connection. So I just gave it a little push towards the center, held it, and screwed it back down.
That's it! It's fixed now. No need for replacing anything. Just poorly drilled holes and a few things not lining up correctly!
So hopefully anyone else that's having this same problem might have some luck in using this fix. Good Luck!

Your not alone with this problem.
I had to fix mine. The warranty is less than impressive.
The trouble is going to be the Power Supply/Backlight Inverter board.
This is the picture of yours:
This is board # BA71F0F01042. Replacement boards are hard to come by.
Fixing the board like I did seem to be the only option. If you need info on fixing it, let me know.
