I have been searching through the posts but I haven't found a solution to this problem.
Just got a (real) ultra and when I first switched it on, everything looked good, did the calibration and self test which passed without problems.? Switched the unit off and then on a few minutes later and the screen lit up as usual but it has no signal trace as it did originally.
I have tried holding the toggle to one side and switched it on but still no trace.? Tried unplugging the battery and updated the firmware with several versions, some quite a bit older but still no signal trace showing.?
Am I doing something wrong or does this need to be returned for a working unit?
Thanks in advance,
