We have a VMC4020 and the monitor is blowing the fuse for the 120v input
I removed a monitor from a working machine and it blew the fuse about 2 hours later s@#&
I repaired the old monitor and installed it in the machine I removed the replacement from and it works.
I repaired the fuse on the monitor in the troublesome machine and attached it an external 120v source the fuse does not blow
I monitored the power supply with an oscilloscope but nothing was observed
any clues?
Regards
Matt
