My machine was working great yesterday and then when I went to startup today the CRT won't turn on. Some of the LEDs in the back panel are not on either. I checked several fuses but no luck. Any thoughts? It has a 10t control. How fussy is the incoming power? I had to step down from 480v 3 phase to 220 but we are close to a hydroelectric station and the voltage is not incredibly consistent. Blew a 5 amp on the power module awhile ago. Had a contactor( sorry probably not the right term. I'm a machinist not an electrician). For the hydraulics go as well. I have only had the machine powered up for a couple of weeks and am just getting familiar with programming so have not used it much! Help please!
