I replaced my convergence board in my Samsung HCN653WX and now it only plays in black & white. But the PIP is crystal clear and in color. What can it be??
I don't have a quick answer to this, if it came into my shop i would have to troubleshoot it. Do you own or have access to an oscilloscope, dvm and the manual. if so then i will help you through this troubleshoot. As i can see there is no straight answer. Unless someone here has seen this problem before, and since i have seen you post about this before, i assume nobody here has a fast answer. Try to get the manual through www.servicemanuals.net collect the necessary equipment and post back, i will then give you test points based on the service manual.
