Done it and same resultsTry measuring those voltages again with your black probe on the respective GND pins.
same results as wellPerhaps but it might be different if you use the black probe on the reference "GND" that is adjacent to each 3v3, 5v and 12v etc
yesMeter on dc range..?
yesMeter tests ok..?
yesInput voltage/frequency match input requirements..?
although it's working and there's an output voltageBoard looks to have been pretty warm around the switcher ic and associated bits.
i need to know the cause of the higher output voltage,
although it's working and there's an output voltage
So what to check?Could be a fault somewhere in the feedback section.
noDoes the capacitor next to it have a domed top
at what pic exactly should i do the measurementWhat voltage do you measure at IC1
at what pic exactly should i do the measurement
how to tell if it's?If IC1 is a KA431 or similar,
can you explain to me how can i?You should be able to work out the set voltage.
how to tell if it's?
