      Yeah, call a technician. Sounds like some fuses have popped in the PSU.
      It's 106 miles to Chicago. We've got a full tank of gas, half a pack of cigarettes, it's dark and we're wearing sunglasses.

      Hit it.

          There's an adjustment wheel to the left of the display to adjust the lcd contrast. I know, it can't be that simple.

              As TonerMunkeh says, call a technician. The fuse opened for a reason, replacing it won't fix the problem.

                  Switch the machine off, pull out BOTH sides of tray 1, switch on. if the screen returns its the loom on the underside of the right hand tray rubbing on the tray runners and shorting the 24v line to the panel.

                      Thanks guys. I checked everything as suggested, but everything are in a good conditions. Is it possible because of control units?
