Hi,
I am trying to fix a friends CNC machine Nakamura Tome TMC-200, I have been able to replace power supply, amplifier etc as it had been sitting for a long time without use.
I am now down to the controller board A16B-2200-066 and replaced it to find out the replacement board will need programming.
So I have looked at the original board and found a component on it has failed, by using a thermal camera.
It had short circuited so was blowing the 5A fuse. Photos attached of offending item is the one with 19 on it, others on the board are marked like the CZ7 one is.
Thanks in Advance
Regards
Mark
