Solu&on step
•
1) detec&on on the main control board impedance between two C55/C67: 13.5K; 80V transformer electric,
measuring voltage is U20 1.46V [1, 7 feet of 4 foot [to] between impedance: 13.5K standby voltage: 1.46V]
•
2) detec&on on the main control board impedance between the ends of 100 C54/C62:?; 80V transformer
electric, measuring voltage 0V
•
3) the main control end of the D8/D11 plate <s, with a mul&meter measuring (block) two diode
resistance: Infinity [nega&ve] does not make a mistake when measuring
Fault detec2on circuit of E14---- current (/CUR_A or /CUR_B signal zero offset
value is too large)
