I am looking at purchasing 4 of these from a close friend. He says that on one of them the LED display is not working, and they have not troubleshooted it. I see that these have a feature where the LED display is turned off, if that feature is activated is the display off even when you first power up the device? Thanks for any help on this, if is not the menu, is there a fuse or anything like that, or would this be a send in to have repaired kind of thing.
The light still works fine, everything functions as it should.
