Sounds like you may have multiple problems if your game is not playing blind.
As for the G07, if it's dead, check the 2 fuses. If the large pigtail fuse is blown then you have a problem in the power/rectification section (900's). E.g. a shorted diode(s) or other issue. If the small pigtail fuse is blown then 99% of the time your flyback and/or HOT have failed. If neither fuse is blow and you are certain you are getting power to the chassis then your monitor is in HV shutdown which could be a number of issues.
If your small fuse is blown, handle with care. The large filter cap on the chassis will hold a very nasty charge for a very long period of time (months).
If you need it serviced, PM me. I repair these and other raster monitors. I will walk you through the process to safely remove the chassis and discharge that filter cap. I also have several G07's in process of being rebuilt and repaired to sell if you just want a replacement.
