Help with picture on samsung LN32a330J1D

[Speedracer5]

A few weeks ago the bottom half of the picture on my samsung LCD tv got covered in horizontal lines and started ghosting and showing duplicate images displayed vertically. Here's a video of the problem - http://www.youtube.com/watch?v=XKPXgGYx4RM
I disassembled the entire television and have not found anything out of the ordinary. The connections, wiring, and capacitors on the main board, power supply board, and t-con board all look fine, both on the front and back of the board. I have a good deal of experience in computer repair and can usually spot shots on boards, but these have stumped me. Also, the ribbon connectors between the t-con board and the lcd panel itself all look to be in good shape. I read that there is a problem in samsung tvs that these come loose and can cause these kinds of problems, but on this tv they all look to be uniform and connected properly. I don't want to have to buy a whole new television and would rather just replace a bad board, but I can't figure out what the problem is! Does anyone have any insight into this issue? I may just order a new r-con board, but I really can't afford to buy a part that has a slim chance of resolving the issue. Thanks guys!
edit- I also have already tried disconnecting, cleaning, and reconnecting every connector and ribbon cable between the various boards.

This is probably a tab bond fault, they come in various forms and can sometimes be repaired....

I tried doing that, pushing on each of the ribbon cables as well as on the glass and on the connector itself (while wearing non conductive gloves) and the picture never changed. So far I am at a loss...

Did you try the small ribbon chips on the side of the LCD panel?

This panel only has ribbons running along the top, and I tested all the other components (the tv is 100% disassembled and the components are set up on my test bench). I decided to order a new t-con board as someone accepted an ebay offer for $20 for one. Hopefully it'll fix it but if not, I can live with 20$ wasted and a fun project to keep working on. I'll keep you guys posted!

well, that didn't fix the problem, so I'm pretty much down to it being a connector. I know it is none of the connectors on the top of the panel, but I can't find the ribon chips on the side of the panel, I only see cables on the top... I'll post pics when i get off work.

I believe these panels integrate the side drivers into the top tabs, using some very very fine drive lines to the side of the panel. I have no idea if a fault like that would be fixable.

Well I'm pretty much given up, I have taken the entire television apart, fully removed the screen, back light, etc. and still can't figure it out. Thanks for the help guys!

I have the same model with a ghosting black and white picture. It doesn't appear that there is anything wrong with the LCD. Do you want to sell your boards?
