Yoke wires are ok. Also, I found this helpful writing over on KLOV (pic below). So, there is still something wrong with the pcb. I have ordered some cleaning supplies for the pcb as Tighe has suggested and once I clean it, I can eliminate if anything was not making contact or not. I stumbled up on another cheap untested DK PCB and it had a prob. So, I took the cpu board from that one and linked it with the video board of the one I have been trying to fix. And it worked! So, my prob. is somewhere on the CPU board. And, I still want to fix it.
