The device turns on, the display lights up and then turns off spontaneously, activating the protection.C30/ c31/ c32, approximate voltage value across the capacitors, c30 15v/ c31 19v/ c32 19v.Check the inverter circuit, in the protection stage, if the capacitors are shorted; c30/ c31 /c32 / 100kpf. To turn off the protection, it short-circuits the collector and emitter of transistor q9, and damages whether the device works normally.xmichaelx
