Hi all, just got my HCx a few days ago. Mine ALWAYS comes up without the backlight on. I thought this was a "feature" of the software upgrade to 2.5. I just press the light button twice after startup, once brings up the light level bar set at zero and the next quick press sets the light level to its previous level.
I also am experiencing the low contrast problem. Last night I left the unit in the car, it was below 30 degrees out, and it started up in low contrast (after I double clicked the light button). Restarted the unit, double clicked the light button, and it was at full contrast. I'm worried this problem will only get worse and contrast will be lost every time I start it up. Or I may need to make a battery change out in the cold woods and when I restart the unit it is low contrast only and never restarts to full contrast - this could leave a person lost.
Thanks for all the great posts so far.
