Hi,
I'm trying to repair a SkyTronic G-12-030 inverter (300W max), but without the schematics this may be a long shot
One of the Low (12v) Voltage MosFETs (RFP50N06) had blown. I have replaced it but still no joy.
When I apply 12v input, the unit just beeps, the fan is not turning, (I hear) no oscillation (I expect to hear a faint humming)
I noticed that a 556 timer chip did not get power, I also found a 7812 in the circuit. It also does no get any input power.
Any one any tips?
Schematics would be wonderful
Or does anyone know the OEM brand name of this unit?
Any tips are greatly appreciated,
ChrisV
