As this machine is pretty new, you will most likely have to be the troubleshooting trailblazer. First thing I would do is a through visual inspection of the insides, specifically all board to board interconnects. Then go over the boards to check for obvious physical or thermal damage. If you have electronics knowledge you can trace the low voltage power supply that powers the control boards. Check voltages at the primary filter caps and before and after the voltage regulators. You should be able to look up the data sheets to see if things are in spec. Probably a 5 volt rail for most of it, but it could be 3.3, as a lot of new micros are going that way. Since the display is dark, that's where I would start.
However, be sure to talk to support to get the OK to proceed. I'm not sure how many of these have been repaired, so they may not have much in the way of statistics on what goes wrong with them, apart from the common shipping damage from being dropped and such. If you are under the gun to finish a bunch of work, it's probably not the right time to try and troubleshoot an unknown machine. Rent or buy a replacement machine. You can always sell it later.
Long arc, short arc, heliarc and in-the-dark!
