I purchased the USB Microscope - 5.0 Megapixel / 220x magnification / 8 LEDs in October and it was working great up until this afternoon. Now, the LED light ring won't turn on. Turning the dial to change the illumination level has no effect. The microscope still provides video data to the computer (Win 7) although it is extremely dim with no lighting. Changing USB ports has no effect. I look through the software settings, but didn't see an option for turn the LED light ring on/off.
Has the LED ring died or am I missing a setting somewhere?
