As I mentioned, I do not have DC power where the cell cord wires connect. When opening the box, there is a circuit board attached to the cover with a ribbon connecting it to the main board, and the main board behind a metal cover. I assume my problem is with one of these two items? Being that there is 240v going in, and no DC volts coming out, I assume my problem is with the main board that also carries the transformer? I can purchase the whole complete main box with metal cover online. I have posted a pic below. I just didn't want to buy it if it could be the smaller board attached to the display cover that could be the problem?
