I have a Samsung PCN5425R rear projectin HD ready TV and when I try to use the Perfect Focus I get NO SENSOR DATA on the screen. The other problem I am having is that I can't align the blue convergence. The red works fine. I bought a convergence board online and it actually made things worse. So, I'm returning it and putting the old board back in. I was hoping the perfect focus would help clear some of this up. Any help would be greatly appreciated. Thanks, Brandon
