KDL-32L5000 Picture problems

[ZRICE28]

I picked up a KDL-32L5000 there are horizontal bars moving from top to bottom on the lower 3/4 of the screen. I already checked all of the tab bonds and applied pressure to all of the ribbons. No change. I used spray freeze and found that the image corrected itself when I froze the upper right hand side of the metal frame holding in the screen. Behind that spot, on the back side of the tv, is the inverter. I took off the frame and pressed along the whole right side of the screen itself, removed and put back on the inverter, and am having the same issues. Not sure where to go from here. I've read that it is most likely the tab bonds or the tcon, but why would the image appear correct when freezing the right hand side? The only ribbons attached to the screen are along the top. All that's under the frame in that spot is plastic.

Thanks in advance.

You cool down the TFT driver ICs (little rectangular IC) which bonded to the flexible circuit board between the LCD glass panel and the tab, those ICs run hot and they use the frame as the heat sink.

So, this one is dead then? I've searched around and I haven't seen anyone replacing the IC you speak of. I'm assuming it got to hot at some point and fried out...
