    4020 Cnc88hs Control won't boot

    like the title says it locks up during boot at the Cold start instructions. I was running it this morning, went to lunch came back powered up and no go. Powered it off and on a couple of times hangs at the same startup screen. I've never had a problem....strange. Any ideas?
