Question about Nikon Coolpix 990 Digital Camera
Posted by Anonymous on
The problem is the part where the flash unit (ES_TOP_PCB). It's a small plate on top. Failure of the "chip" (SMD FET 8 pin ZBOC4), which controls the high voltage capacitor charge (80mF / 310V) and circuit continuously draws current from 250 mA. The problem is in the feedback when a flash capacitor charge circuit should stop charging the capacitor. Chip is located next to the high-voltage capacitors. On this plate are two chips, one control, and the other driver and it was a mistake. Check and diode (R 8) before the capacitor. This failure was in one of the serviced cameras. Another possible defect in the display. The third failure was in transport lenses and there is a malfunction focus electric motor, but this can be heard as the motor constantly running back and forth. This fault and the fault display requires a change modules. Lots of luck ..... ERNESTO from Croatien
