Re: S1100 PSU

It is very common that high pitch noise occurs because of the display inverter. My unit does the same. You can fix it by replacing the inverter with a S950 inverter. The inverter must be played on the same board as the s1100 inverer, the board of the s950 will not fit the s1100. so it needs a bit of modding.
check the inverter thread at mpc forums, loads of knowledge in there.
