Angry ChIP Assay Sonication Problems

Hello all, im getting problems with my ChiP sonication steps. I follow the steps from the Santa Cruz kit. Im using all the reagents according to the manufacturers instructions.

The problem is that when I sonicate my 293T cell nuclear extracts, and then I reverse cross-link, and then phenol extract my DNA, I get only a DNA that smears.
Can someone hand me some suggestions please?
thanks
