One of my technicians went to this machine earlier this morning and found the display blank but backlit and sometimes blinking. He said that when power is cycled, display is backlit but blank and none of the components seem to start their boot-up process and normal functions during warm-up cycle (fuser heating, motors turning, LSU spinning, nothing). But,
he can turn machine off, go into a maint. mode (08), and the display works perfectly with no lock-ups or lines or missing info. Seems to me as if it's just not getting through the boot-up so as to let everything continue to come to "Ready". I tried to talk him through entering the "Function Test" menu (holding down 1 and 3 and turning power on). Figured he may be able to try to perform individual tests on components and such to narrow down possible source of problem. When trying to enter the function test, the display reads "ERROR NO. = FF1". This is the only machine of this model I have in the field so I don't really have any warehouse or boneyard part to use on it. We did have some severe weather come through that area day before yesterday and I'm thinking lightning may have gotten to it. I believe it may be a Main Board that's bad but not 100% sure. Anyone ever seen this or have any suggestions? Thanks,
