question about reading voltage

[mrel]

Hello
Did voltage reading on sonicview 8000hd the power supply got reading of 30 volt should be 22 volt on pin 3 and 4 both pin read 30 volts which is 8 volt more than should be,is that bad or good to have 8 volts more than what is call for.?

A lot more information is needed.
Many power supplies have a higher voltage so that the voltage drops to say 22v when fully loaded.

mrel,
How do you know what should the voltage be?have you got a service manual?
In general it is a bad thing not to have the correct voltage with such a big difference,
but one must be specific to the circuit.

The voltage printed on the circuit board where pins at.

mrel

and is that supposed to be voltage BETWEEN the pins 3 and 4
or from either pin to the 0V rail ?

how about a sharp clear pic of that part of the board, so we know you have interpreted it correctly
