Hello everyone I am new to this site. I have a Kiwa Excel center with a Fanuc 3m model c. The other day I was running the machine and it was operating in auto without problems. I went to shut the machine off and while hand wheeling the z down the head jumped a little. A watchdog alarm and others came up on the screen but I cant remember what the others were. I hit reset and ran the program in auto one more time with no problems. I shut the machine off and when I tried to restart it nothing came up on the screen. I opened up the control cabinet and there are no led's lit up on the motherboard. I tested the voltages on the power supply and on the motherboard and all are correct. After that I tried disconnecting all of the connectors on the motherboard except the 3 on the top. There was still no screen and no led's lit on the board. What else can I try? Thanks everyone. Dan
