DSO5072P self calibration issue (SOLVED)
Edited by nbk at 2022-9-30 06:25Hi everyone,
I want to share with you my little experience withHantek DSO5072P
It is a great scope,
But lately it start to have some issue with the cooling fan, so I tried to fix the problem and I did it by lubricating it.
After some days, the signal disappear and there is no response anymore.
I tried self calibraion and it works for some days, then the issue reappears.
there was a thermal issue, and with the help of my thermal camera, I spotted the hot spot, it was obviously the Low Dropout Voltage Regulator KA78R05 which have around 100 degree Celcius.
Fortunately I have a spare piece of it with a different manufacturer.
I replaced it and everything went fine after that
