    Satellite receiver Power supply higher voltages output

    i also have tested the big cap 47uf 400V and it gave me 36uf, is that acceptable? and can it cause such higher voltage in the output ?

    Satellite receiver Power supply higher voltages output

    yes yes yes although it's working and there's an output voltage i need to know the cause of the higher output voltage, cause it cause the receiver to hang up while working or give me "searching for signal" for some channels

    Satellite receiver Power supply higher voltages output

    This power supply output voltages is higher than it should be, what could be the cause Standard voltage actual voltage 23V = 32V 12V = 18.5V 3V = 7 V Next 3V = unstable 0.5 to 1.6 V 5 V = unstable 6.8V to 7V

    Samsung Monitor repair

    first you should have a multimeter, and the after connecting the power supply to power source make sure if there's an output voltage or not

    Help fixing Digital Multimeter Proskit MT1210

    well you can see the colors of the original and find out it's value the same way " that's why they put colors on resistors " and then replace it with the same value resistor

    help fixing satellite receiver power supply circuit

    ok here's the update changed the power IC and still the same issue no output voltage change the Optocoupler and still the same issue no output voltage so what else could be the issue for no output voltage
