Good morning. I am having a problem with my machine. One of my transistors got fried. I removed the motherboard and changed the transistor and I put back the motherboard and the machine is now turning on. The problem is when I put back the FPC cables the machine was just flashing but if I remove them it switches on. I then traced all cables and realized that if I connect to slot MCN7 the machine does not switch on. I don’t know where the machine is short circuiting. Can you please help
