My superb analyzer stopped working
EXACTLY after one year (i found a print on pcb with 19.02.2015 showing as date) ...
The unit does not do anything anymore
Can not be switched on ... no beep ... no blink
Plug in charger and it does not show the charging sign on display (that round sign showing charge of battery when charger is plugged in)
It does NOTHING
Batteries are well charged (charged externally cause I did not know if internal charger works)
When charger is plugged in then the orange led in the unit is lit (so the fuse is ok and it is just the charger fuse)
Or is there a second fuse somewhere that I did not find yet??
Between batteries and mcu???
Is there anything I can check BEFORE sending the unit back in for repair????
Is there maybe a hidden function somewhere to reset the unit and bring it back to life?? ... maybe a bridge to be set on pcb???
I am fear to send the unit complete around the globe if maybe I can solve it here
Maybe I can test (and change) the switching regulator or a different part??
As you lknow I have built an mchf ... so I know stm32 and I also know surface mounted parts ...
So ... PLEASE help me
Your friend and betatester
ps I am glad that I did not sell my 901h yet ... otherwise I had nothing to measure with up to 3 gig
