My 5.5" Crystal Sky won't shut off - even disconnected and with the battery unplugged!!!!! Anyone else had this issue?
Must be able to turn the external battery off as well as the internal battery.if the monitor is on and you need to change the external battery (flat) the internal battery is used to keep the monitor working (but not the screen display) so when you install fresh battery all still works.
Sometimes it takes a couple of tries to turn off. Pressed on/off button ... message appears .. turn off button the monitor fails to turn off so I try again and usually works. Screen turns off ... no fan noise .. monitor is off.
