Toshiba 55" projection tv 55H70 blue bowed line from bottom	Can't Post

Hi, I'm getting a blue bowed line from bottom corners of the TV. The bow is about an 3” or so thick or so thick and starts in bottom two corners and bows up to about 1/4 way up the TV. The bottom portion under the blue rainbow is a solid yellow crescent. I have tried convergence settings to no avail, since it only moves them slightly.

Any help would be appreciated!

Thanks,
Craig

The STK392-110 IC's were the problem, thanks! Took me awhile to get at it and solder the new parts in, but fixed the TV for under $15.
Thanks much!!
