Unfortunately the situation is the same
Upgrade 01.00 AM
Accidentally I touched a capacitor with my multimeter and now voltage on PL401 is 0V
I swap them again and I got voltage again but 4,4V without PL401 and around of PL401 zone PCB is warm
So P401 is damaged
Resistance to ground of PL401
Side PU400 = 270kohm
Side system = sometime drops to 42Kohm sometime rise to 42Kohm
Pin401 resistance to ground
1= 2,56 Mohm
3= rise up to 9,5 Mohm
