I recently had the convergence board replaced in my Samsung HCN653WX and yesterday I turned it on and its showing black & white but the PIP is showing full color, also the perfect focus reads no sensor data when pushed what happened?

"the perfect focus reads no sensor data when pushed what happened?" - when the board was replaced they did not save the data to the autofocus section. I have not worked on that many Samsungs, but if you have no sensor data, the tech should have saved the new convergence data. the black and white picture may be a loose plug, not sure, but if you have secondary symptoms after a repair, usually it is a missing plug. The tech should have caught all of this stuff. I would be calling the service company that fixed your tv. Sounds like they were not paying attention to what they were doing.
