Après avoir débranché puis rebranché la batterie tout a redémarré normalement.
Peut être un reset du programme et des défauts en mémoire?
========================================

Hello I had this problem; an almost identical hair clipper.
After disconnecting and reconnecting the battery, everything restarted normally.
Maybe a program reset and memory faults?

After I today 22 feb 2018 received twenty (KIA)431 smd components and had replaced the old 431 smd component (V1 in schematic) the Hair-clipper was working like a new Clipper again!
The S1 3.7 lithium-ion charging boards I also specially had ordered (But which never arrived!!) won't be needed for this repair afterall. So the Holtek processor was still completely working and no other components were defect!

Hi Anthony, you said it right about logic analyzers being a completely new tool in our equipment. I'm happy the article was new to many readers too. It absolutely is a very promising and exciting new tool in our shack!
