Insurance tube F101 is normal, the main switch power supply output voltage measurement is 0, that is a switching power supply is not started. Current instantaneous power measurement thick film integrated circuit IC101 (KA29100) {3} feet not starting voltage. The machine USES resistance capacity startup mode, then instantaneous short startup capacitor C103 ends, the switch power supply work, explain C103 failure or open circuit, with 2.2 u F / 400 v capacitance change, troubleshooting.6gVservice manual download site
