I have a mainboard with the serial no. DE-21721B and I want to replace it by the old one in a Mutoh Spitfire 90. But I'm not sure that it matches the machine. Can you help me please?
In addition, can you repair that kind of mainboard? And if yes what is the price and how long does it take? In fact, some of my friends in Iran have the same problem and seek to find a solution.
Best Wishes
