screen won't light up on edge cs
today I left my truck idle for 20 minutes while I loaded a machine and when I got into the truck my edge cs was blank. I pressed the enter and menu button and nothing. I had been driving the truck all day wo any issues. I called edge and they said to check the lighter fuse, lighter works fine, as does the power port. I have not had a problem with the programmer at all and have done the updates as available. I don't need all the high power tunes and like the gauges with this unit. Any advice would help. I was told by edge that the tunes are loaded and the monitor does not need to be hooked up after the tune is loaded to drive the vehicle.
