K8098 with backlite on but now video

Hi, I bought 2 K8098 from Jameco in California, unfortunately after building the two kit, one of the kits does work, just blank lite screen. The other one works. I decided to swap the IC1 on both of the unit. After doing that I start powering the two unit and the unit that doesn’t start to work and the other one didn’t to work, with a lite blank screen. So I concluded that the IC1 is the problem.
Now is there a way to send me another IC1 to replace the one that doesn’t work?
