    iRA 4035

    Had bad lightning storm during the night. Customer calls this morning saying only green light is on..no display. Upon arrival, found that as soon as main power is switched on, green power light comes on, Main controller fan comes on, but no initialization at all. Screen is blank. No HDD codes or anything, finisher does not cycle either.AC power is coming into power supply correctlyBoth Green and Red Led's are lit on Main ControllerHave 12v and 3.3v at different points on Power Supply. Being supplied correctly to main controller, but none to DC controller. Cannot locate 24v anywhere. Main switch does have the 3.3v signal going in and returning to PSU.I'm assuming bad power supply. But, is it supposed to get some sort of signal from Main controller to generate 24v? Machine was on surge protector. Customers computers had shutoff due to power going out in the night..Reading the manual, not sure whether or not the PSU is the problem, or the main controller. Thinking HDD would throw code....Any input to narrow down?
    assuming lightning damaged PSU, though fuses are all good. Or...maybe power cycling killed the HDD/ MC

      I went by last week and indeed, it was the main controller 1 PCB that fixed it.
