•
measure if there is short circuit between GND and J1 Pin#1, if do, change C74, if did not
help, go to next bullet
•
try change J1 power jack, if does not help, board unrepairable.
1.2 check 10 – 28V output on Schottky Diode D1 if ok, go to next chapter, if not, follow
recommendations:
•
try change Schottky Diode D1, if does not help, board unrepairable.
