If, when the unit is running on battery only, the activity LED is flashing, check the LCD cable.
If the LED is not flashing - you've got other hardware or firmware problems.
Since there are a number of manufacturers of the original Nanovna, and the quality varies, you'll have to go slow and eliminate each area.
Good luck.
